Epiphone made valve amps way back in the Sixties, mostly copies of Gibson and Fender tube amps. It quit the market and only re-entered in 2006. Now it has a bunch of valve amps aimed at serious guitar players searching for that tonal warmth that you only get from a great tube amp.
The most recent of these is the Epiphone Blues Custom 30, which the company describes as having “enough power and sound-shaping features to cover virtually any gig you could book, and achieves it all without cluttering the all-tube signal path or sapping the core tonality that shapes the beating heart of any great amp.” Sweet.
