I suspect you may still have a problem.
To quote from the BYOC Scrambled Octave into bumpf -
In addition to being an extremely rare and expensive vintage effect, the Ampeg Scrambler is also an
extremely cool octave up fuzz. The actual fuzz itself is very unique. Like most octave fuzzes, it's a very rude,
nasty, ripping-velco sort of fuzz. But unlike most other octave fuzzes, it's not overly saturated or gated. It's
surprisingly open, articulate, and responsive to pick attack. And the actual octave up part of its sound is very
Which doesn't seem to be what you get with your build.
On the other hand although I could not find any You Tube demos of the BYOC Scrambled Octave there are quite a few of the Ampeg Scrambler and various clones and self builds. Listening to some of those may give you a better idea of how it should sound. I have to say I found some of the demos put my teeth on edge. This one is pretty good - http://www.youtube.com/watch?v=XfzP7ubrYlM&feature=related
I prefer the sound of my JOYO Voodoo Octave (post my fixing all its reversed electolytics) which is a clone of the fOXX Tone Machine as cloned by Fulltone in their Ultimate Octave. I use it followed by the BYOC Envelope Filter which takes a lot of the nasty edges off the sound. As already pointed out the cleanest octave sounds are achieved with a neck pickup with the tone rolled off.
Ouch!! just checked the price of the Fulltone - £154.40 ... glad I paid about £25 for the JOYO.
