Re: Xotic SL Drive add to a already overdriven Marshall
Those xotic pedals are fantastic, but I think they're meant to be used in front of a clean amp. You can totally use it in front of a dirty Marshall, but I think other pedals would do that job better. I've only used the BB Preamp which is a different sounding pedal altogether, so I'm assuming that the SL is similar just voiced like a Super Lead.
