Simplified Silicon Tonebender 3-Knob

Doh! Somehow I had forgotten that you had posted a link.

Hm...Does it sound much fatter in person? Regardless, I drew up a vero layout in class the other day, I may put it together later tonight.

it sounds better of course. i do not have a good rec gear at home.
i was about to draw a pcb using photoshop. i was going to include a coupke of extra things to make it customizable, like the possibility of adding a parrallelcap to help the 10uf crappy electro.

Don't like DIY Layout Creator? I was probably going to use that if my drawn vero works and thus verified, to make an easily readable and clean layout.

i've been using photoshop since version 1. i'm too old to change!!!

I added in my gallery a PCB and Layout TIFF file at 288 dpi (2.6mb)
I think it is correct, let me know if you find errors.

Still need to test it, but here's a pic!


I hope it sounds good!

Hey, it looks better than mine! 

Let me know how it sounds.

Haha. It's essentially your PCB on perf. I didn't feel like etching. Voltages seem great! 4.6V on Q2.

[azrael]

Wow, sounds great!
I recorded a clip (complete with shoddy playing) with my iPhone, I'll have to upload it later.

It works really well, very much like the Ge version. Excellent design!

Does anybody have the schematics of a silicon Tonebender mk1.5?

All I could find is this germanium tonebender mk 1.5:

I'd imagine any silicon fuzz face schematic would do just as well

I imagine you're using NPN silicon?

if so, just plug them in with everything the same except:
flip the polarity of the 5uF and 25uf electrolytic capacitors
put a 10K trimpot or potentiometer in the place of the 8.2K collector resistor of Q2 as a bias control (most seem to like 4.5v here but let your ear be the judge)
use a positive power supply with NPN transistors
