Like you, I've tried all kinds of amplifiers and have interacted with a great many terrific amp-builders (They all seem to be from the same "good guy" stock, to me, for some reason, especially those in Texas.). I've recently had contact with Doug Sewell & now own a couple of his amps. I think Doug is the best of the best & the Sewell amps, which I've been curious about for a while but never was able to try one, are tremendous! I bought a Texaplex 100 head with a master and a gain boost option that was damaged in shipping due to terrible packing by Guitar Center in Dallas (I know...I know. What did I expect? But I should say that the GC did respond to the problem with a partial refund to my satisfaction). Although Doug wasn't the seller, he contacted me & insisted that he do the repairs at a very low cost (It's with him in Texas now.). He was particularly interested in protecting his reputation, even though he had nothing to do with the damage to the amp. While it's there, he's also doing all his recent upgrades (some developed in collaboration with Paul Reed Smith) & making any changes I might want or that he'd recommend. Before I sent it to him, I was able to make it work in spite of the damage. Even in that state, I was blown away by what a great amp it was and the range of tones. It's the best gain I've heard--smooth & thick yet always articulate--I haven't heard modded-Marshall overdrive tones this good since I started using a Rocca-modded Naylor that has been my "gold standard" for years. This amp does a lot more than the modded Naylor, though, in addition to the gain. I was so impressed that I bought a 25E Texaplex combo, too. Right now, Doug is getting rid of the EF86 circuit (his recommendation), turning it into a 50-watt Texaplex, adding a couple of features I want, changing the speaker and doing all the new upgrades......at extremely reasonable costs. Doug Sewell's amps deserve to become better known and heard from coast-to-coast, I think. Anybody out there had similar experience with Sewell Amps and Doug Sewell?
