Posted January 22nd, 2016 by Tom Wiltshire & filed under Distortion, Overdrive, and Fuzz, Stompbox stuff. You need a very high input impedance/low noise op-amp (discrete or IC) and some seriously good noise management techniques (they're claiming -100db noise floors). In addition, I really mellowed out the pedal by putting a . Craig Anderton's "Electronic Projects for Musicians" book has a good schematic for this, and I'm sure there are lots of other sources also. Nothing special here. The rest of the schematic is the same as the one you reported. It features the legendary 4558 integrated circuit and provides multiple EQ settings with four DIP switches accessible from the outside of the pedal housing (High, High Mid,  A tiny buffer circuit to use as part of another circuit or by itself. The signal leaves op-amp 1 and goes through the resistor end of the vactrol, encountering some resistance.

If there is a reference voltage already established in a circuit to which you are planning to add a buffered input, the existing Vr can be tapped and used for the buffer's reference. Buffers are used EVERYWHERE in audio where a signal is driven with a power source. Handmade in the USA. The first portion of the circuit is the input Op Amp Buffer Schematic Guitar Beyond that, I dare them to explain what will change in an opamp, cable or PCB By using a buffer with a very high input impedance, you are giving the guitar. A pedal like a tube screamer cuts the lows, boosts the mids, and compresses the signal so that a loose mushy amp (like a mesa rectifier on neutral settings) becomes really tight and cutting. What surprise me is the IC2 of TL072 used for LED purpose. What is a buffer? A buffer is an active electronic circuit that keeps your guitar signal strong and preserves the frequencies of your guitar sound. The pedal is apart slightly so you can see the board.
