About Blumentritt Amps
A friend had an AA764 Champ-style kit that someone had built and it didn't work, so he gave it to me, just the raw chassis without a cabinet or speaker. After looking at the schematic, the build instructions, and the amp itself, I was able to determine serveral mechanical and electical issues, and was able to make the amp work correctly, and it sounds the way a silver faced Champ should sound. My appetite was whet.
After studying various schematics and circuits, I drew up what was to become the Texas Tone 12. It has some of the essence of tweed style amps, although it's not a copy of any historic or actual amp. For those of you who study amps, it has high and low gain inputs, two gain stages separated by a gain control, a split-load phase inverter, a post phase inverter volume control, a low frequency oscillator for a tremolo circuit, and two cathode-biased 6V6 power tubes in a class AB push-pull operation.Not being an existing design, sourcing parts was a small issue along with creating a chassis layout and build order from scratch. There are reasons that people purchase kits, and not having to look for parts and invent a layout and build instructions are decent reasons. Also, with a kit, you know what the end result should look and sound like.
When it was all put together, tested, and played for the first time, I was pleasantly surprised. It not only sounded great, but it had that dynamic touch sensitivity that guitarists long for in a tube amp. It has a very nice "sweet spot". However, I may be not be unbiased in my assesment of my own amp, so I called a better guitarist than me, who gigs regularly, and who has played through several different boutique, production, and modified production amps. His assessment may be found on the comments page.
I call it the Texas Tone for a couple of reasons. It has that Texas blues kind of tone that only seems to come from a good tweed style amp, and it has Tremolo, an essential ingredient for certain blues, Gospel, twang, and swamp sounds. That tremolo circuit took quite a bit of tweaking, but the result is worth it. One builder calls it a hypnotic slam effect, and that's a pretty good description.
That's how I got started building amps. My effects pedal and pedal board building came about first, because I wanted to build my own stuff, having been disappointed with expensive mass-produced pedals and boards that seemed more about marketing than substance. My first pedal was the Swamp Box tremolo pedal, and I gigged with that for several years before building the Texas Tone 12.
The line is expanding. Current models include the Kick Box clean boost, the Armadillo Tone tube preamp/boost, three sizes of wooden pedal boards, and the Texas Tone 12. Up next, the TexTone 20, another take on tweed tone, and the Big D, a modern take on the venerable 5E3 Deluxe, but again, not a copy. It's not that I have anything against copies or kits, it's just that there are so many out there, and it's kind of a 'been there, done that' kind of thing... what, another 5E3?
