FEA Photon Fuzz

Thanks for the compliments!!:)

Do we know is this is based on an already existing fuzz circuit?,...or is it Frank's own design?

This is a multi-stage fuzz circuit. The first fuzz stage sounds similar to the hundreds of other hard diode clipping circuits (with the bite control at minimum). The second fuzz stage is an optical-FET clipper that is engaged by the bite control. This FET clipper aggressively flattens the signal peaks further and can add a flavor of square wave fuzz (depending on the drive and bite settings).

Does anyone know if the octave-up/full wave rectifier distortion circuit is the same on the dbd?

The octave up in the Photon sounds different from the octave up in the DBD because of the way they are implemented. The octave in the DBD is before the distortion circuit and in the Photon it is after the fuzz circuit and EQ… so, the Photon’s octave distortion can be much more pronounced.

A large majority of my GAS has been killed since my most recent acquistion, but I'll throw it out there:

I want clips.

Here's the first clip, with a very fuzzy / dry tone mix: Invalid Link Removed

I'll work on putting a few more together over the next few days. Right now there's a lightning storm so all my gear is unplugged, but tomorrow is supposed to be a better day for weather. :)
 
So after playing with it for a couple of days, I thought I'd give a quick review:

It's a very inspiring pedal. Loads of sounds in there.
The main thing is this: almost every control interacts with the others. For example, if you're cutting mids, you have to tweak the drive to compensate, which in turn interacts with the Bite control, etc...
I personally love it, as you need to spend a little time with the unit to get a feel for the particular interactions (and I haven't even fiddled with the internal trim pots).

It came out of the box with a really gnarly fuzz tone, but I have found my personal fave: a lot of dry signal blended in and just a touch of hair added, and as a bonus, when you step on the octave it just gives you extra grit and cut. Fantastic.

As a disclaimer, I should point out that I tap on an 8 string guitar (tuned to low E like a bass), so a bass will definitely be a different experience.
But between the great EQ and the versatile colors of fuzz this thing can coax, I'm sure my low end brothers will dig it too.
