Buffer

What is a guitar buffer pedal for?

In certain situations in which we have many pedals, long cables or there are certain pedals that do not understand each other well, they result in a poorly defined final sound, with a lot of bass and off, regardless of whether the pedals are connected or not.

This is where one of the most underrated pedals comes in: the buffer. Basically, a buffer is a circuit that will replicate exactly to the output what is connected to the input and, more importantly, apply that output unchanged (transparently) to the next guitar pedal in the line. In short, a buffer pedal improves the quality and high-frequency response of your effects chain, eliminating impedances and noise.

There are three basic settings for placing a buffer: just before a very long cable, between pedals that don't sound very good together, or typically between a wah and a fuzz.
