I am considering options for my Epi Tbird Pro IV (4 knob active). I think it has a Seymour Duncan 2 band pre and overall the output seems pretty polite to me. There's no trim pot to set the preamp output level either. I've tried raising the pups a little and this doesn't really help much, it still sounds a bit meh. I have no idea what the pups are in the thing. Am I looking at new pickups? New pickups and electronics? Are there after market pickups which will drop straight in? The existing pups are 37.5mm x 90mm with quite rounded corners... I'm not overly concerned with the (minimal) resale value of the instrument and I do really love the plank - no neck dive, beautiful playing neck and it looks like rock'n'roll.
