The CFH is a very hacky effort. It's just a static SHO with clipping diodes and a tone control.

Sounds cool. Would that be a 1590A Grease Gun?

The Sparkplug with all external pots, oh yes!!!!

Also: what's the CFH from the projects page? Your own design or based on something?

(Also, on a side note: how about shrinking your silicon Tonebender to 1590A size?)

Does anyone know if Alpha is discontinuing these regular 9mm pots?

Some of the usual shops here in Europe (Musikding and UK Electronic) haven't had them for months.
I just saw that there will be a lot of new 1590A projects, so I should stock up.

Boss man doesn't seem very demanding, "Big Muff" is enough, so he now has what he wants. Maybe you should build some other fuzz now - it will be a nice surprise and your friend might appreciate that.

Showoff!

Digging up this thread again.

How about a version of the Blackout Effectors Mantra? Especially now that Blackout seems to be out of business.
Never seen a DIY version of this, although it was quite popular some years ago. It's a high gain overdrive with a lot of hair:

"Equally capable of invoking the sacred sounds of a classically refined overdrive AND summoning wickedly raunchy drive, with more crunch on tap than the overdrive moniker usually entails. With such a wide palette of tones and character the MANTRA will feel just as at home at the feet of the stalwart blues crowd as it will the quintessential rock & roll protagonists.
The MANTRA utilizes amp-like circuit architecture, with multiple cascaded MOSFET and JFET gain stages to insure the most natural, touch-sensitive overdrive conditions possible and a seemingly endless range of clean-up with your guitar"s volume knob. We burned a lot of midnight oil to make sure that the MANTRA could get down with vintage-type, low output single coils and hot humbucker pickups alike. From gently fingerpicked melodic phrases to bludgeoning riffs that you"ll want to play over and over and over..."

Schematic etc.: http://revolutiondeux.blogspot.com/2012/07/blackout-effectors-mantra-overdrive.html

There was a version available with a Low Gain Switch which bypassed a gain stage. I can't find a schematic for that though ....

On the Projects page in the top left corner you'll find "Archives".

It's in the "Sunking" zip.

Rej had a few tough spots. Only uphill from here.
Get well!

(LM386 based, though)

looks like the schottky diodes have a Vf between .55 V to .875 V ... you could double those up, go with 2N7000 +bat41 pairs, or  3mm LEDs if you want more volume and less clipping ... of those choices, I think the MOSFET would be smoother and more amp-like
if you want more clipping you could go with 1n400x rectifier diodes, bat41, or germanium ... I think the germanium sound better, even if doubled up for a more reasonable Vf.
now I kinda want to build this thing with mosfet clipping ... damn it, another project

Great, thanks! That's a good starting point.

Build it, it's worth it!

Thanks. Which type of diodes would be a good start?

The Runoffgroove Ginger is intended to be an Ampeg in a Box, primarily for Bass, but this pedal has been on my board for years, I love it, it's perfect for guitar! Thick yet open, dynamic, super effective Tone control.
The one thing though: it could have a bit more gain. I always have to hit it with a booster.

Mine is built on a TH custom board, but you can get them from Fuzzdog, OSH Park, and other places.
http://diy.thcustom.com/shop/rog-ginger-v1-0-pcb/
The TH Custom doc says: "The original circuit features 1N5818 diodes for D6/D7. I have fun listening to it with the same red LEDs in this place."
Mine does, indeed, have 1N5818 in D6/D7. Does this affect gain much?

Question: What could I do to squeeze a bit more drive out of that pedal without it changing its character at all?

Thanks!

I was feeling like it, so I made a 2 layer pcb for this suitable for 1590a. it's available via oshpark here:

if anyone verifies the layout please let me know.

I ordered your board, verified!
