Really nice graphics and very clean wiring! Where do you buy those small electrolytics?

An italian wooden wine box full of 1590A pedals. In order from right to left:
1) The Good, Tube Screamer 808 with Fat and Bright toggle switches;
2) The Ugly, Plexitone with boost pot and clipping toggle switch;
3) The Bad, Crunch Box with external Presence pot and clipping toggle switch;
4) Mephisto, Stone Grey, no mods added;
6) Tube Llama, Red Llama specs with Full Madness toggle switch (10M resistor);
7) Tone Reaper, Tone Bender MK II with AC128 and voltage inverter;
8 ) Black Goat, Triangle Big Muff with increased gain factor, Mid pot and Cut (input cap), Clipping and Feedback toggle switches;
9) Raven, Rat with Character pot (ruetz mod), Clipping and Cut (input cap) toggle switches;
10) Tarantula, Super Hard On, no mods added.

Same problem, the led blinks right but the repeats are out of synch. I've tried 2 different taptation kits, 2 different sea urchin boards and 2 different pt2399 chips: delay totally out of synch (or useless tap tempo, if you wish).

Hi guys!
I'd like to add a Send/Return to a great bass pedal and DI, the Tech 21 Bass Driver.
Can I put it between SW3 and C21?
I want the bass driver distortion and the other send/return pedals to go in the DI section of the pedal . Is this the right way?

I've done this one! Verified! You can choose what to put inside your 1590A

Is the tube llama just a switching of the one resistor on the toggle switch to give it more gain, or is it more than that?

Yep, it's the R7 mod, 10M

Thank you!
My Mephisto is based on the Rainy Day Schematics, that I supposed is based on the Stone Grey schematics, there are no mods on my version.

If there's someone interested in the Mephisto and Red Llama layouts I can upload 'em on the project board.

Red Llama/Tube Sound Fuzz Hybrid



Stone Grey/Rainy Day



Two Crushers/Crunch Boxes with toggle switch for clipping leds or silicon diodes and Medusa/TS808 with Fat switch and Bright Switch, no footswitches but direct IN & OUT for every pcb.

Have you ever heard this pedal?http://youtu.be/SqijZmqKUQM

I can't find anything 'bout it, no layouts, no schematics, nothing!

OK nice. I want to build a small amp to lay down on my bench to test the circuits... Maybe this is a good option

I uploaded the layout!

Sweet jobs Man
What can you tell us about the ruby amp? Loud?

Inside there's a LM386N4, at 9volt it should be a 1watt amp, maybe something more.
Well, it's loud! I use it as a headphones amplifier and with the volume pot around 10 o'clock it's loud enough to tear my ears apart!
I've used it with a 150 Watt speaker and it sounded good too.

1590A Tone Bender mk II with onboard voltage inverter



Tone Bender mk II without voltage inverter and a strange vintage box!


Plexitone/Boneyard with two Level pots (one for the crunch, one for the Higain)


Zero Point Micro with modulation switch & pots


Sea Urchin with 3 presets + Rub-a-Dub reverb with boost pot and (inside) tone pot



Noisy Cricket/Ruby Amp with several mods




My wine box guitar tuned GDAD (sometimes GDAE) + Hot Red Head + Clean Amp Cabinet (in a chinese box)

4 transistors as usual!  
I've drawn this pcb layout to fit easily inside a 1590A (leaving space for the jacks too)...
so in a 125A there's plenty of room!
You can find my etchable layout in the link, if you wanna build a little (really little) monster... I suggest you to do the Feedback mod... it's crazy but really playable!

Mammoth build using the Madbean's Sabretooth etchable pcb
Really nice sound fuzz, tested both with guitar and bass

Trinity Feedbacker build using my personal layout (here's the thread: http://www.madbeanpedals.com/forum/index.php?topic=8392.0 )
I've found that the Tone pot wiring is inverted (1, 2, 3 in place of 3, 2, 1...)
I've jumpered the 39k resistor and used a 10K B pot for the Mids... it seems much more usable!
