The Unsung Hero of Your Pedalboard: The Buffer

There’s something mystical about guitar effects pedals. Their eccentric designs, seemingly infinite varieties, and the unique sonic landscapes they provide, capture the imagination of guitarists worldwide. Yet, amidst this array of stompboxes, a silent but significant player often goes unnoticed – the buffer. This article aims to shed light on this unsung hero of your pedalboard, separating myths from reality, and highlighting why the buffer should never be an afterthought.

A buffer is a relatively simple device that converts high impedance signals from your guitar into low impedance signals. This might seem like technical jargon, but in layman’s terms, it means the buffer helps to maintain the integrity and quality of your guitar’s original tone as it travels through your chain of pedals and cables. Buffers become increasingly important as your pedalboard grows, or as the total length of your cable runs increase.

Myth 1: “Buffers change my guitar tone.”

This is a common myth that dissuades many from exploring buffers. The truth is, a high-quality buffer is designed to be sonically transparent – it shouldn’t change your original tone but rather preserve it. The issues often arise from lower quality or improperly designed buffers, which can indeed alter your tone, leading to these misconceptions.

Myth 2: “True bypass is always better.”

While it’s true that ‘true bypass’ pedals allow your signal to pass directly through the pedal when it’s switched off, without going through any extra circuitry, it’s not always the better choice. The more pedals and longer cables you have in your setup, the higher the chances of losing high-frequency content due to the increased capacitance. This is where buffers can save the day by driving your signal with enough strength to reach the amplifier without losing any fidelity.

Myth 3: “More buffers equals better sound.”

While having a buffer in your chain is crucial, it’s a game of balance rather than a matter of ‘more equals better.’ Too many buffers can lead to overloading your signal and, thus, may degrade your tone. The key is to find a balance, often achieved by placing a buffer at the start and end of your signal chain.

Reality 1: Buffer Placement Matters

Knowing where to place your buffer can have a significant impact on your sound. A common practice is to have a buffer at the beginning of your chain to preserve your guitar’s signal from the get-go, and another at the end to ensure that the signal is robust enough to make it to your amplifier with minimal tonal loss.

Reality 2: Not all Buffers are Created Equal

Just as with pedals, not all buffers are created equal. Factors such as the quality of components, circuit design, and manufacturing quality can all influence the performance of a buffer. Therefore, it’s wise to invest in a high-quality buffer that can provide the transparency and signal strength necessary to preserve your tone.

Reality 3: Active Pickups and Buffers

If you use a guitar with active pickups, you might wonder if buffers are necessary. Active pickups already have a buffer built into their circuitry. However, the total length of your cable runs and the number of true bypass pedals can still affect your tone, making an additional buffer at the end of your chain a wise choice.


Buffers are the unsung heroes of your pedalboard. They help maintain the fidelity of your guitar signal throughout your signal chain, ensuring your tone reaches the amplifier as pure and unadulterated as possible. So next time you find yourself diving down the rabbit hole of new effects pedals, spare a thought for the humble buffer. It might just be the missing piece in your pursuit of tonal perfection.

Buffers aren’t the sexiest component of a guitar rig. They don’t provide the wailing sustain of a fuzz, the ethereal sweep of a phaser, or the subtle ambiance of a reverb. They are more like the invisible hand guiding the sonic palette of your guitar from the strings to the amplifier. But understanding their role, dispelling the myths, and appreciating the realities can bring a new level of depth and clarity to your sound. And isn’t that, after all, what we guitarists are always chasing?

If you’ve read this far, I encourage you to go ahead, experiment with buffers. Understand their power and limitations. The quest for your ultimate tone might be a footswitch away. The unsung hero is waiting for its spotlight; give it a chance to shine.
