I'm happy with my clean "always on", and love my lead sound...just missing that dirty/crunch in-between sound. Humbuckers/slit coil PRS Clean: Scott Henderson RC-Boost: Right channel always on, left channel I use for "more". Lead: The Dude. Nails the Blue-line Robben Ford sound that that I go for. Fuzz/thick: Analogman Sunbender. Love it, but needs to be first in line for my ears, so not best option for mid-crunch.. Just missing that mid-crunch dirty sound...think David Grissom. Crunch and overdrive when slammed, but cleans up when volume is rolled off. I have, and not happy with: Xotic AC-boost, Xotic BB for this purpose... Thinking of: Jetter Grissom JHS Andy Timmons or angry Charley Rockett .45 Caliber: Love the Rockett pedals, but just sure if the marshall in a box thing is what I'm after. I don't care much for the BB in my rig, which seems to be similar in aim. I Use a Carr Viceroy....A Fendery Princeton-type boutique that I love..... I've thought about maybe a second RC-boost...has anyone tryed stacking two together? Absolutely love the transparency.....I'm a Grissom freak, but just not sure how the Jetter would response on a Fender style. Let's hear your thoughts?
