I bought one years ago and never really tried it out. Been stored away since. Maybe I have to dust it off and see if it will give my RC a run.
I was amazed that a large # of people who owned the pedal were unaware it was a dual function Boost/OD. The gain knob is actually a blend control for the OD and when its full CCW the OD is out of the circuit and its literally a straight up clean boost with bass and treble. This is different than using a TS as a boost because you are ALWAYS running through the drive circuit even with the gain on 0 and you are therefore subject to the built in EQ response (midhump).
Here's another little tidbit:
The RC boost is essentially the Fulldrive in comp cut mode. That's right people...the RC is a TS based pedal. Do a search on the DIY pedal forum and you will learn all.

The AC and RC and BB are basicly plain TS-808 copies with an added active baxandall tonestack. The AC and RC are absolute idenditical, except the no. of cliping diodes in the FB-loop (to me it's a joke to sell 2 pedals, a simple switch for the diodes arrangement and 1 pedal would have been the better solution for the user).
The BB's front end is more similar to the reverend divetrain, except the tonestack, on the train it's passive. Common to all Xotic drives pedals is "bad filtered" Bias-divider (BTW: the OCD use the same divider and values) and a soft sounding I-buffer, so the sound is slightly more compressed on the AC and BB w less highs and a somewhat flabby bass when played on low volume. Played on it's own the sound is not so good, but they come alive as a low gain drives in front of a BF amp when played on stage levels. The RC has nearly zero compression due to the amount of diodes in the FB-loop.
Wow. Are you sure about this? Amazing.
Yep, sure! The white RC has 6 Diodes (>+>+>) in parallel w (<+<+<), the yellow AC has the stock TS-clipper, diodes are 914, 1S15888 or sim. The I-buffer work with 3V BIAS on the resistor, the rest w 4,5V, for a bit more headroom switch the 470k BIAS-R in the buffer to the normal 4,5V VREF. The AC/RC is nothing but a downsized BB, basicly they are all TS...
This schematic shows the same 4k7/47n network associated with the clipping feedback loop as a regular TS, but the BB (I use one) does not have a pronounced midrange at all - in fact, I typically use an EQ bumping 400 and 800 Hz to give me some 'cut' in a live setting.I haven't torn the goop off of my BB's board to see what's what. Any thoughts?
The 4k7k/47n will not produce any mid hump at all, only a bass cut with rolloff frequency about 720kHz. The overall tone of the BB is the result of the Baxandall-tonestack, the 4k7 connected to the basspot and the 10uF is mainly responsible for the mid shaping, increasing it will increase the mids in the BB, decreasing it will decrease the mids.
