hi guys ive just done my first two gigs using my laney R5 and Epiphone T-bird. im not shy to say that all the knobs on my amp have me scratching my head. can anyone suggest some good settings for me? i have the bass's pickups set to "max volume" sound........both right up, and as i play ramones, sabbath, whitestripes and priest so im after that classic rock "crunch" sound. thanks for reading.
