Looking to get a tone that is best described as 'raw' and 'dry.' Similar to the 'brown' sound, but something more edgy. Been fooling around with my Boss GT-Pro and can't quite seem to dial it in. Perhaps the guitar's pickups and the amp you play through as just as important, but with the pre-amps and amp simulators in this unit, along with all the effects, there must be setting out there that come close. Any help appreciated.
