well to get technical if you are using it as a "clean boost" it IS gain, you are talking about using the gain / drive / distortion knob, which clips the signal not nessisarily in respect to the gain, clean boost is fine to boost the signal, but if you are pushing the randall's input into clip with the clean boost from the pedal, it is going to NOT sound like a tube amp being pushed it is going to sound like a bad fuzz pedal, which i suppose could be a usable sound if you like that bees in a can sound, which is purely subjective. i guess it depends on what kind of a sound you are going for, it's deffinatly not the route you are looking to take to get classic sounds, i'd even say it'd sound more industrial than metal even, i know sandman personally, and i am certain if he tries to push the randall with a bad monkey, it'll be on ebay in 2 days
