Title: MindBender
Post by: Mich P on February 02, 2015, 09:17:47 PM
Hello all, my latest pedal, a Phillip BRYANT mindbender (NPN Ge tonebender with some tweaks). The box is from Mac Walker (DIYstompboxes). A huge Thanks to Jon Stomptown
who is design the PCB with his traditional Maestria (he normally should post the project here for the community).
I use quite low gain transistors ('round 60 for all spots) with low leakage (around 0.030mA) as well.
I also play with the imput cap to ground reduce to 3,3nF to recovery some highs at low gain setting. Same for the output cap bump it to 470nF (!) again it keeps some lows when you rolling back your volume pot and really help to get a good crunch for example.
I kept the others originals values for the Fuzz Central project, except for the fuzz pot where i highly recommand a 1KC.
So i really happy with the sound of the circuit, i can get greats differents sounds by playing volume and fuzz pots.
I'm sure some of you have NPN Ge trannys in stock waiting a great project,
You have one !
Mich P.

Amazing Mitch!  I love the graphics and the wiring is perfect.  Now I need to build one myself!  Are these enclosures still available?  Link?

I will add this to the member projects forum and to my website tonight.  I will also share this on osh for those who would rather have a fabbed version.

Super cool artwork and enclosure. Straight up badass. This is something I would buy.

A wedgified Hammond 1590J is very similar in size.

This is printable sticker covering with transparent sticker to protect.
Advantage when you are boring with the artwork you can easely change it.
Jon, Davent were fastier than me.

I think this looks great! That is a build to hang onto, for sure.

Jon, that would be awesome if you could share the project. I'd love it if there was a simple, fabbed MkII layout with board mounted pots. I've resisted boxing the Supa Fuzz I did on vero as I know it's going to come out with the wiring not looking that good. I'm assuming I would just need to reverse the electros and the diode for a straight PNP build?
