Rat clean boost mod

[destro]

Anyone know how the clean boost is implemented a la the deucetone rat? I am assuming that it is no clipping diodes....

[somnif]

Yeah if you look at the board, the clipping diodes are soldered to the switch itself, and the clean side is just a jumper.

[DGWVI]

Yup, no diodes. It'll still be dirty, and able to fuzz out but the lower end of the distortion pot will have just a bit more range

[destro]

Yeah, when I read clean boost, I was trying to wrap my mind around how simply removing the diodes would remove the distortion. Thanks for the clarification, DGWVI and somnif

[DGWVI]

It definitely doesn't remove the distortion, just takes away the compression the diodes add, but the opamp is already being driven into distortion. It's a cool sound, though. A little harsher than a Turbo Rat, a little louder, and up to about 9o'clock on the distortion pot will give you a cleanish boost.
It may just be a placebo thing, but I also feel it stays a bit more dynamic through higher gain settings

Repeating what's  already been said, this reminded me of a recent TGP thread where a Pro Co rep responded:
"On the Deucetone we also have a no diode setting which we call the clean rat, although it's not anywhere close to clean."
