After recently discovering what an active parametric mid control on an old PV Session 500 did for my tele, a sad memory came back..that of my old Gibson Lab Series amp, which had(IMHO)the absolute best active mid control ever to land on a control panel. I'm looking for one now again..in particular, the 2-12 L-5. I would also consider the 4-10 L-7, and the 1-15 L-9. I'm also willing to swap an early(82') Randall RG-80 112SC combo in excellent condition, including original footswitch, for a comparable Lab Series. Let me know guys. Thanks!
