Smart… horrible people over there in Chino. You want to talk about incredible customer service???? Zesto. Not only is it great sounding gear the service is second to none. Full disclaimer, my preamp had a bad tube socket from getting whacked laterally nothing to do with Zesto reliability
Not only was the repair super reasonable, I decided to get the ESP Power supply update while it was there.
I feel your pain, my first tube amp was VTL and it was almost my last. Lule Manley is the most arrogant person I’ve ever had the displeasure of dealing with. That amp sounded great when it worked…..I switched back to SS after that POS for a while
I have had several tube amps since and none have needed repair aside from a bad tube or blown fuse . Quicksilver builds super reliable gear , check out their new KT Mono amps
