    I've found that the Comp-Cut mode of my FD2 with the boost on has THE tone for me. Thru my /13 its the tone I've always wanted. I really don't use the other 2 modes of the FD2 at all because I dont really like the distortion sound. Now I see people saying the FD2 is a Tubescreamer, but I think the Comp-Cut must be something totally different. Can someone explain what this side of the pedal is doing? Or even maybe have a diagram of the comp-cut mode?

    The Fulldrive II is based upon the Tubescreamer circuit. It's a popular and good-sounding variation on that theme.

    The Comp-cut feature is quite simple: it removed the clipping diodes from the circuit.

    How does it make it so much louder than the other settings?

    oh, and thanks for your reply :)

    Diodes restrict the flow through a circuit... kinda like a uni-directional resistor. Now considering some clipping sections of TS808 clone have as many as 3 diodes, lifting those diodes out will increase the flow through the circuit and hence create a boost in volume.

    I think that is the reason... probably want someone to verify.

    Pretty persistent in your quest to build a FullDrive, eh? Good luck and have fun... I believe you also have an answer over at the BYOC forum!

    I only use the comp setting too. Love it.

    haha, yeah. I want to do a sorta frankenstein project. I guess I have too much time on my hands.

    It's never a waste of time to create something and learn new things. I'd rather be in the garage building pedals than watching TV or playing video games.

    FDII in comp cut into a maxed out FatBoost running at under 9v makes a pretty good imitation of a Boogie Mark IV's Lead channel (for a while, the FDII-FB1 was my backup in case my Boogie broke down).

    Does that mean that the comp-cut mode is only a "Boost" mode, not an "OD mode ??? no clipping at all ?

    No. Other parts of the circuit can will clip with enough signal being pushed through. In fact, you can get a cool medium-gain overdrive tone by maxing out the gain knob and selecting the "Boost" mode (footswitch). The tone is not super-saturated, but is very "old-school" rock, with better picking dynamics than when not using "comp-cut". Some guys use the FDII only in this manner. (You do need to finesse the output volume knob however; it's holding back an extremely hot signal. Iif you bump it up even just a little, your guitar will sound louder than heck.)

    Yeah, be careful with comp cut, I almost blew out my eardrums the first time I tried it. Without the compression, you can get a huge volume boost.

    i just bought a FDII mosfet, and that's exactly how i use it, except i implement a Timmy for a crisper sound...I use the Comp Cut for low gain, then add the Timmy with gain at 1030 for mid gain OD, then hit the boost for High Gain!

    i win:) lol
