I picked up a beat up old Laney Pro Tube 50 combo for guitar. It has a nice tone and plenty of drive and pwr. It lacks in the low end and definition, no matter what PUs, or guitar I use. I play hard to heavy with runs and sweep picking. It has a generic eminence in there with 2 jj el 34s and 3 fender 12ax7s that i think are new. Any speaker suggestions? Weber, Celestian, Reverend maybe.
