It's in the title. Here's a quick sample of the BD-2 pedal straight into a clean sound from a JMP-1 preamp.
Guitar is a Lag Roxanne Floyd, using the bridge pick-up (Seymour Duncan JB) from start to finish.
As I said, the preamp is a clean Marshall JMP-1.
Power amp is a Marshall 8008 valvestate.
Cabs are two stock Marshall 2X12.
Some blackmore sounds (well, it's more my idea of a Blackmore sound) on the CP60 strat, straight into a Boss blues driver then into a clean sounding Marshall JMP-1.
All the variations in the sound come from the guitar.
Here's what a Boss GE-7 equalizer can do when put in front of an already (lightly) distorted preamp.
Signal chain is : Lag Roxanne Floyd (Seymour Duncan JB pick-up used through the whole video) into Boss GE-7 into Marshall JMP-1 preamp into Marshall 8008 valvestate poweramp and tow Marshall 2X12 (stock ones).
First sound is GE-7 off, then I kick it in.
