Guitar Buffer PCB: The Ultimate FAQ Guide


I know you’re looking for high quality guitar buffer PCB.

Or, you would like to learn more about guitar buffer PCB.

A reason this guide will answer all your questions on guitar buffer printed circuit boards – keep reading to learn more.

What Is A Guitar Buffer PCB?

Guitar buffer PCB

Guitar buffer PCB

A guitar buffer PCB is a device that will provide transformation for electrical impedance from one circuit to the next.

Besides, it aims at preventing the source signals from the effects of whichever current or voltage that loads may be formulated with.

The guitar signals are buffered from load currents.

How Does A Voltage Guitar Buffer PCB And Current Guitar Buffer PCB Compare?

Here is how these two compare:

Voltage Guitar Buffer PCB

This buffer will transfer voltage from the first circuit having high output impedance to the second circuit having low input impedance.

The interposed circuit will inhibit the second circuit from loading the first circuit which may interfere with its functionality.

The voltage of the second circuit is influenced by the first circuit output impedance when there is no voltage.

This is because it is larger than the second circuits’ input impedance.

Current Guitar Buffer PCB

This buffer functions by transferring current from the first circuit with low output impedance to the second circuit with high input impedance.

Interposed buffer will inhibit the second circuit from loading the circuit of the first current unacceptably.

Also, when it transfers unchanged current, the amplifier becomes a unity gain buffer or current follower.

This is because the output current will follow the input current.

What Are The Examples Of Voltage Guitar Buffer PCB?

Buffer PCB

 Buffer PCB

These include:

Op-amp Implementation

Unity gain buffers may apply negative feedback to op-amp by connecting the output to inverting input.

Besides, unity gain means voltage gain of a single but you expect a high current gain.

Single-transistor Circuits

Some unity gain buffers may include the following:

  1. Bipolar junction transistor
  2. Field-effect transistor
  3. Vacuum tubes

What Are The Examples Of Current Guitar Buffer PCB?

Common unity gain entails bipolar junction transistor in a common-base setup or MOSFET in a common-gate setup.

A Single-transistor circuit is an example of a current guitar buffer PCB.

What Are Some Examples Of Single-Transistor Circuits In Guitar Buffer PCB?

Guitar PCB

 Guitar PCB

There are various configurations of single-transistor circuits within guitar buffer PCB.

They operate as a buffer to isolate the load from the driver.

In most applications, NMOS voltage follower is the accepted setup since they have high input impedance causing digital systems to require minimal current.

Under single-transistor circuits, we have the following:

Common Base

This will offer low input impedance and high output impedance.

A common base will buffer the current.

Besides the voltage is high, the current gain is minimal and the overall power gain is minimal than other single-transistor configurations.

The common base is rarely used but offers benefits since the input and output base is grounded hence, reduces unwanted feedback.

This is because the base provides a barrier between the emitter and collector.

Common Collector

This is also known as the emitter follower since emitter voltage will follow that of the base.

Here, the voltage gain and unity are close, hence used to buffer voltage.

Also, voltage gain is unity besides the gain being high.

The common collector provides a high input impedance and low output impedance.

Common collectors is a buffer circuit offering high input impedance to inhibit loading and low output impedance to operate the following stages.

Common Emitter

This is a popular kind of configuration as it offers medium input and output impedance.

Besides, you can describe the current and voltage as medium, however, the output is an inverse of the input.

This will offer suitable performance making it a popular choice.

What Is The Relevance Of Guitar Buffer PCB?

Guitar buffer PCBs will isolate the incoming high input impedance levels from the guitar into unity levels.

Put simply, it will maintain the strength of the signals that run via the guitar buffer PCB configuration.

Guitar buffer PCBs are vital in maintaining the tone of the guitar that you have mastered as it assists in enhancing the tone of the guitar considerably.

Besides, the cables you use in guitar buffer PCBs are not a suitable technique for transferring signals.

This is because every foot of cable impacts the signals since it adds capacitance.

Most impedance imperfections that arise mean you will lose most high-end guitar frequencies if you have a longer cable.

Guitar buffer PCBs are vital in the configuration and should be in a location before the strength of the guitar signals dip.

This terminology is also known as tone sucking since the guitar will lose power to finish the circuit, hence the brightness and clarity of the tone fades.

How Do You Use A Guitar Buffer PCB?

The best way to figure out where to place your guitar buffer PCB is with some experimentation.

A general rule is to place the guitar buffer PCB between guitars and the first pedal, and no further inwards than the endmost overdrive pedal.

When you use many true bypass pedals, the ensuing signals will be weaker since they will not affect any incoming signal.

The fuzz effect sounds bad when it follows the guitar buffer PCB, so maintain these in the earlier parts within the chain.

Signals from guitars will have full strength if it instantly follows the guitar buffer PCB.

Once you have the guitar buffer PCB in place, the length of the cables coming before the buffer and any pedal will degrade the tone.

Besides, even if you fail to use guitar pedals, guitar buffer PCBs are important.

Most guitar buffer PCBs have a power socket, input, and output jacks with no controls, just simple plug-and-play capabilities.

Other guitar buffer PCBs have extra features such as stereo output or in-built boost or tone shaping controls to assist in shaping your signals.

Having several guitar buffer PCBs require you to have some volume boost.

What Kinds Of Signal Loss Can A Guitar Buffer PCB Improve?

Guitar buffer PCB

Guitar buffer PCB

There main causes of signal loss that guitar buffer PCB can improve include the following:

  • Tone sucking pedals
  • Long guitar cables of 15 feet or more
  • Pedals with a low input impedance
  • Long signal chains containing several true bypass pedals

Besides, if your setup has few or no pedals, odds are that you will not require a guitar buffer PCB.

If you apply few effects pedals or long guitar cables, you need to find out if the guitar buffer PCB will have an impact on your tone.

Here is a test that can guide you on how to understand how important a guitar buffer PCB will be to your setup.

Begin by playing the guitar normally and pay close attention to the high frequencies.

Proceed by plugging your guitar into your amp directly using the shortest guitar cable and play the same tune.

If you notice the tone of the guitar is clearer and brighter when you plug it into your guitar amplifier directly, consider a guitar buffer PCB.

Do Pedalboards Have A Preinstalled Guitar Buffer PCB?

If you have a DIY guitar effects pedal, you will know if the pedalboard has a guitar buffer PCB or not.

However, when you purchase a pre-built pedalboard, it may be difficult to know if it has a guitar buffer PCB.

Some manufacturers ensure they place guitar buffer PCBs within their pedalboards.

This means if you purchase from them, you are certain that it has preinstalled guitar buffer PCB.

Besides, make sure you check with the product description to know if the pedalboard contains the guitar buffer PCB.

Where Will You Place A Guitar Buffer PCB Within The Signal Chain?

Placing a guitar buffer PCB within your signal chain is more of a personal preference.

Depending on the size of your configuration, you may require several guitar buffer PCBs to restore the signals to the correct format.

Here are areas you may place your guitar buffer PCB:

Beginning Of The Chain

Placing a guitar buffer PCB at the beginning of the signal chain nullifies the long cable capacitance effect on the guitar signals.

Middle Of The Chain

Placing a guitar buffer PCB in the middle of your signal chain is a suitable way to push the guitar signals through larger pedalboards.

Besides, this is a configuration to try out if you have 8 or more True Bypass pedals.

End Of The Chain

Placing a guitar buffer PCB at the end of the signal chain will clean up and restore the high-end frequencies.

This is particularly suitable before the signals hit the front part of the guitar amp.

How Do Transistor And Op-Amp Guitar Buffer PCBs Compare?

When it comes to guitar buffer PCBs, two types exist, that is, transistor and Op-Amp guitar buffer PCB.

Besides, there is no specific and correct version of guitar buffer PCB to use on your pedalboards as it boils down to your personal preference.

Here is how these two compare:

OPAMP Buffer Kit

OPAMP Buffer Kit

Transistor Guitar Buffer PCB

This type of guitar buffer PCB needs minimal power to function than Op-Amp guitar buffer PCBs.

Besides, they can handle up to 90% of your buffering requirements.

Transistor guitar buffer PCBs are more compact than Op-Amp guitar buffer PCBs.

This feature allows you to easily fit the transistor guitar buffer PCB within your pedal enclosure.

While Op-Amp guitar buffer PCBs need fewer components to construct, it is much easier to build transistor buffer PCBs.

All you need is a single transistor, two capacitors, and two resistors to build it.

Op-Amp Guitar Buffer PCB

This type of guitar buffer PCB is more of an overkill when they operate as stand-alone systems.

Besides, Op-Amp guitar buffer PCBs are suitable when you are manufacturing drive pedals.

This is because it offers spare gain that you can use with your circuit.

Besides, transistor guitar buffer PCB contains no extra features to use.

However, Op-Amp guitar buffer PCBs produce a hi-fi sound for some people’s taste than the natural transistor guitar buffer PCBs.

Also, Op-Amp guitar buffer PCBs are easy to build.

When Should You Not Use A Guitar Buffer PCB?

Besides the benefits of using a guitar buffer PCB, there are instances that it may not be necessary to use.

If your guitar applies active pickups or in-built preamps, a guitar buffer PCB at the start of your signal chain is not necessary.

This is because these guitars have lower output impedance meaning they maintain the high-end frequencies using the onboard electronics.

If your guitar takes 9-volt batteries, chances are they have active electronics.

This means you require no guitar buffer PCBs at the start of the signal path.

Besides, if you have several guitar buffer PCBs, some level volume will be lost thus requiring the need to include boosters.

What Are The Benefits Of Using Surface Mount Components On A Guitar Buffer PCB?

Also known as Surface Mount Devices [SMD], these are parts that you will directly mount on the surface of the guitar buffer PCB.

Here are the benefits of using SMDs in guitar buffer PCBs:

Tight Tolerance

The parts of surface-mounted components have a higher tolerance than thru-hole guitar buffer PCBs.

For instance, the tolerance for carbon-film resistors and metal-film in thru-hole guitar buffer PCB is 5% and 1% respectively.

However, surface mount resistors have a tolerance level as low as 0.001%.

This means that if you purchase 4K7 resistors, you are getting 4K7 ohm resistors.


Tighter tolerance and availability of parts enable you to reform the same guitar buffer PCB several times with no issues.

Besides, there are some parts that you cannot find in thru-hole guitar buffer PCBs.

What Are The Benefits Of Using Thru-Hole Devices On A Guitar Buffer PCB?

Here, you will mount the parts on the guitar buffer PCB by threading leads in pre-drilled holes, then solder them on specific solder pads.

Besides, this was the first method of mounting components on the guitar buffer PCB before SMD.

The benefits of applying thru-hole devices include:

Easy To Apply

It is easy to work with thru-hole components since they are larger than SMD thus easy to solder on the guitar buffer PCB.

Working with SMDs requires you to think of the various soldering methodologies.

Also, with SMDs, you need magnifying glasses and tweezers to place the components accurately.

Strong Connections

The connection of thru-hole components in guitar buffer PCBs attach on the board via holes, then are soldered.

This assures you as you will be using the guitar buffer PCBs daily.

What Are The Limitations Of Using Surface Mount Components On A Guitar Buffer PCB?

It is difficult to work with surface mount components on guitar buffer PCBs due to their smaller sizes.

For instance, you need magnifying glasses and tweezers to line these components with solder pads on the guitar buffer PCB.

What Are The Cons Of Using Thru-Hole Components On A Guitar Buffer PCB?

The drawbacks of using thru-hole components include:

Component Availability

Some thru-hole components are becoming scarce as fewer industries are manufacturing them since they are moving to surface mount devices.

Large Components

Besides being easy to work with, the large parts need more space on the guitar buffer PCBs.

This means you need larger guitar buffer PCBs to mount them.

What Are The Parts On A Guitar Buffer PCB?

Guitar buffer PCBs contain several parts such as:

  • Capacitors
  • Potentiometers
  • Resistors
  • Integrated circuits
  • LEDs

How Will You Test The Quality Of A Guitar Buffer PCB?

The methods include:

Automated Optical Inspection [AOI]

This test will use built-in schematics of the guitar buffer PCB and compare it to the final product to check for any issues.

Functional Testing

This test will ensure the guitar buffer PCB is operational and conforms to quality standards.

Visual Testing

This involves employing experts to inspect the external components of the guitar buffer PCB.

X-ray Inspection

This entails inspecting the densely populated components on the boars since heavy metals absorb some X-ray thus making the inspection easy.

In-circuit Testing

This involves inspecting the position and fitment of parts using electric probes.

How Does  A Single-Layer Guitar Buffer PCB And Multi-Layer Guitar Buffer PCB Compare?

Single-layer guitar buffer PCB has one layer while multi-layer guitar buffer PCBs have more than two layers.

Also, single-layer guitar buffer PCBs are affordable than multi-layer guitar buffer PCBs.

Multilayer guitar buffer PCBs have a higher assembly density than single layer guitar buffer PCBs.

Also, multilayer guitar buffer PCBs are smaller and lightweight than an equivalent single-layer buffer PCB.

There is more functionality in multilayer guitar buffer PCBs than single layer buffer PCBs such as controlled impedance, more EMI shielding, etc.

What Should You Consider When Deciding On The Number Of Layers In A Multilayer Guitar Buffer PCB?

These factors include:

  • Application
  • Operation frequency
  • Budget
  • Turnaround time
