BJF Sparkle Face - Verified

[anders]

Another collabration between Björn Juhl and Moody Sounds, this time a YAFF with NPN germaniums. I did two layouts, one stock and one with the suggested mods by Björn.

*Edit* Stock spec layout is now verified

Info and working theory here

Sphere80 built the stock spec layout and he reported it sounded fantastic. So I had to build it as well and I can only agree. Thick, meaty and high gain with controls maxed. Good OD tones when rolled back.

It's not as insane as the other BJF fuzzes posted lately, but it's very solid and sounds great into a driven amp. Like
Anders says, it cleans up well and works as an OD - even a clean-ish boost!

The "working theory" pdf is a must read, and there's 20 page thread on the development:

Anders, can you describe the mods? I may make another.
