That tremolo's rad! Great design.

Just a boring JFET Buffer and 9V regulated power supply in one box

gena_p1 that is a sweet-ass looking pedal. Love the graphic!

Nice! Kinda makes me wanna re-house my Uglyface into a better plastic container

Is that an amp?


Oh and here are two build tips for other plastic users:

-Only use sturdy enclosures
-Use stranded wire... the plastic bends when you stomp on and plug things

[nexekho]

It's two parts - a project kit preamp from Maplin years ago (a 5532 stereo op-amp with power stuff) right after the input jack and right before the output with some experimental passive filters inbetween.  Works as a headphone preamp or a gritty as heck distortion.

The plastic does bend a little, but I'm using stranded wire, with no stomp switches and while it does flex a little it's VERY thick plastic and would probably shatter if you stamped on it.

Passive filters:
(bypassable) two diodes fed to the outer lugs of a potentiometer.  Works as a strong noise gate and makes a gritty sound.  Tilt it one way and the increased resistance removes the crest of the wave, tilt it the other and it removes the trough.
Diode clipping - switchable asymmetry and a bypass potentiometer which doesn't work as well as I'd hoped but shapes the tone so eh!  Combined with the noise gate you can get very Gameboy sounds because the wave is clamped to three positions.
A filter I found for converting a square wave into an approximate triangle - some kind of modded low pass.  Combine it with the crest/trough removal and you get an approximate sawtooth wave.
Finally, an adjustable low pass filter.  Get a square wave going up to here and with it at about 95% you can have it chopping away the tail end of the square wave for a very edgy sound.

Was fun!

No RF interference problems? Radio signals?

I use quite a lot of plastic bodied or open bodied pedals right next to a fairly powerful computer.  Only interference I get is when someone turns something hungry on like a kettle or a lightswitch or a vacuum cleaner which is a short pop.

I'm guessing this would only be an issue on anything that can't be breadboarded without obscene noise. Probably not the best idea for a Dr Boogie or something! Wouldn't the worst case scenario be adding a 47pF from input to ground?

470R linear pot WTF? did you have to buy 1000 to get those made?

Yeah, we seem to get 47% instead of 50% pots here, not sure why.  Also applies to capacitors?  You can get a 47nf polybox here but not a 50nf.

yep!..just the way it is in the UK/USA....

[egasimus]

Same thing in Bulgaria. Maybe it's because 47 is in the E6 series, and 51 appears only in E24...

Another Echobase, thanks Taylor for the pcb

Always love a good dose of Shortscalemike in the morning!

Just out of interest, what is that Star Wars themed pedal?  Looks like some kind of dual-stage distortion or maybe an octaver, I dunno

[EATyourGuitar]

everytime I see the starwars rebel flag on a pedal I think of feisty little one pedals. he puts them on every pedal. especially with no writing on it, that might confuse people. BTW they look good.
