Custom/home made overdrive/distortion pedal.

This is a custom distortion/overdrive pedal I built. The design is sorta like a super simplified tubescreamer crossed with an od250. Here's a schematic I drew in LTspice so you can build your own or if you just want to see the design.

Dude, i made this pedal a few weeks ago according to your design, it sounds amazing, great and cheap, cool guitar pedal. Do you have more sucesful designs?

[jaywalker512]

@JDCguitarFan I'm glad you like the pedal. Unfortunately I haven't made any other designs :/

hi dude got some questions before i create my own kind of this:

for power supply: what do u mean by V+ and V+/2?

can you redraw this schematic? i dunno where to put my switch, pots, and that SINE (0 100mV 80). im totally confused now. please make another schematic with clearer symbols. i really want this tone compared to other DIY's but ur schematic is more harder to read for me i guess..

sorry for my english dude. hope u can help me.

@bhorj24 V+ is the main power supply (9v), V+/2 is half of that. The SINE marker is just used for the simulator, but that's where your guitar input goes.

i have one question, what'd the difference between the fat and skinny settings? is it treble vs. base or something? or high vs. low gain? or what?

[jaywalker512]

@ARMYStrongHOOAH17 The fat position allows more bass through the clipping circuit, giving a "fatter" sound.

[ARMYStrongHOOAH17]

@jaywalker512 ah, okay...thanks.

@thesaloniandevil

volume/level pots are usually, if not always, logarithmic...because supposedly the human ear interprets the intensity of a sound wave differently than a distorted sound wave....or something like that.

wow your schematic is pretty simple and sounds great! i built a clone of the wooly mammoth.

@jaywalker512 and where exactly do i put the pedal in the circuit and the gain and level pots like before the resistance or after the resistance
