Saw the Eugene Oregon band "Rye Wolves" last night. Couldn't help but notice the guitar and bass amps were both obvious custom jobs. No faceplates. Painted chassis (powdercoat?) in a headbox. Blatant glowing valves showing through the grill. I cornered the bassist later on and inquired after the provenance of the heads. Apparently the maker is a company called Thermionic and they are neighbors of Verellen. The owner and Ben of Verellen are actually friends and hang out often. He told me his amp is the prototype of all the other Thermionic bass heads. I tried searching for them, but such a generic name (thermionic describes any kind of tube circuit, its a fancy way of saying, an electrical thingy that heats up to pass electrons) is hard to constrain a search around. Anyone else aware of these amps? They sounded good. Kinda Matampish with a little of the thick low mid beef, but also something else going on.
