I did, and they were helpful. It got resolved, but I'd lost faith in its gig-worthiness. Great sounding amp, and I'd have another if the tubes were more secure, but I had to twiddle the settings whenver i swapped out axes. Right now I'm focused on my two ancient PTP dinosaurs, and lovin' 'em! Sure they need more outboard fx, but I already have oodles of pedals. I'm running every axe eventually through this old Lifco 6V6 rig. So far, the V, Tele, LP, and Strat all shine through it. I love the "set it and forget it" aspect that simple amps allow, and I think my small amp needs are addressed. If I ever need a big rig again, I'll likely look for more features, but for now, I'm good.
Never a DUH! moment! Well, almost never. OK, OK! Sometimes never!
