Black Horse – Duplex Drive
« on: August 14, 2019, 07:50:12 PM »
Here is a Black Horse Duplex Drive.  It’s a Cornish SS2 G2 clone.  I’m not a muff fan, so, probably not the best judge to weigh in.  I do prefer this (G2 side) to other muffs I have palyed.





Here are the 1N5401 diodes I ordered from Mouser, made me laugh when I took them out of the foil.

Looking good! Your graphics are turning out great!

I haven't tried the SS-2, but I dig the G-2. Did you keep the stock values or play around to brighten up the G-2?

And those diodes are pretty large. Those leads look to be about as thick as a 1n914!

nice work. Have you changed the stock 2.2uf film caps for lower values in the G2?

That is one beefy polarity protection diode. Makes me wonder if it was just a case of Pete Cornish only having some amplifier or PSU circuit diodes around when he was designing the pedal and sticking with it (seriously, why else run a 3A 100V diode in a stompbox...)

Those Cornish pedals are quite possibly my favorite.

Pedal building is like the opposite of sex.  All the fun stuff happens before you get in the box.

Thanks!  I haven't tried any mods, is there a thread somewhere you could point me to?

I haven't looked into the mods, yet but will probably start.  I actually like the harmonics coming out of the G2 side compared to other muffs I've built/played.  Those have mostly been russian spec muffs.


Oh, I thought I made a mistake and got the wrong size.  Didn't realize those were actually used in the original, that is weird.

Thanks BP!  I'll check it out.
