Input gain knob???

[dexisded]

Hello, i have a question regarding input volume as a control on a pedal. As a beginner, im merely brainstorming on why certain sounds can be achieved through the means i detail in this post so hear me out.

There is a pedal known as the acid cat distortion. This features an input control which acts as a gnarly gain control. I was wondering if an input control is a control which can be universally installed on any pedal as a means of driving the amount of signal hitting the circuit which can then be trimmed in volume using an output control? Thank you for your answers.

Quite a few fuzz pedal circuits have an input level pot used as a gain/fuzz/sustain/intensity control (Jordan Bosstone, most Devi ever fuzzes). I've also seen many diy pedal people suggest installing one in the fuzzface circuit as a "better" fuzz control than the standard Q2 emitter/cap potentiometer.

In these circumstances, the fuzz circuit is running at maximum filth, and the input level pot is a simple means of adjusting (but only capable of *reducing*) the filth level.

Some other fuzz circuits have an input buffer, followed immediately by this type of "volume" control pot that acts as a fuzz level pot in the same manner (DOD carcosa fuzz pedal has it labelled as "input"), and the venerable Big Muff has a Q1 boost stage followed by this same volume/level divider pot, this time labelled as "sustain".

Hi & Welcome..

You're talking about "classic" Volume/Master controls..
(which exist in almost every preamp incorporated into power amp..)
