Well, here's the life and times of Zwengel amps in a nutshell.<P>I started out as Summit Amp Repair in 1993. It was mostly an outgrowth of doing a lot<BR>of repairs, retubing, and hotrodding of amplifiers for guys while I was in college. I started out doing it part time while I was working as industrial coltrols engineer at an injection molded plastics company. In '96 I finally got on "the net" and began doing mods and repairs nationally. At that point I renamed myself Summit Amplifiers.<P>This is where The Banshee comes it. I started getting a LOT of requests for high gain sleeper mods for Fender Bassman and Showman amps which were dirt cheap at the time. We're not talking about a heavy crunch, but great big, hairy balled, massive, saturated, infinite sustain kinda gain! as well as some miscellaneous wake up tweaks to the JCM800 MV's. Then it occured to me that while tweeds and plexi's are killer amps in their own right the musicians coming up now don't have these amps as a personal reference tone. Players in their late 20's to early 30's grew up on Metallica, Nirvana, Pearl Jam, etc. Dropped tunings and 7 strings started coming into the picture so the amps had to be able to support and pass a HUGE amount of low end along with the gain, and nobody, but NOBODY was building hand wired circuits that could hang on this level.<P>So, I went about designing a circuit that could virtually do it all in a single package without loading an amp down with controls and switches. In early '97 I had open sourced the design process on my website with regular posts on the Ampage BBS and low and behold, a certain hand wired boutique amp mfg pops up with an all new "Vintage/Modern" switching option. Coincidence? So, with a new understanding of why Dumble gooped his amps, I squelched the design but quick. The big guys will rip off the innovators and screw you but quick and won't even kiss you afterward!<P>Somwhere around '99 GP magazine started publishing reviews of an Allesandro as well as some other clone/handwired amps and the first thing I said to myself was this is a joke right?! I can build a higher quality amp on my worst day. So, now we're off to the perverbial races. I stated designing custom transformers, custom chassis, enclosures, etc. All my chassis are 16g powder coated cold rolled steel. I had Jeff Suites who does many of the cabs for Victoria Amplifiers do my enclosures, and Schumacher Electric did the winding of my transformers, which is a story in it's own right! They've moved ALL production south of the border, and are already having QC problems. I refuse to farm out any parts that aren't built with American labor, even if it costs a few extra bucks! So, I'm shopping for a new company to do my trannies. I'll probably wind up with either Lenco or TMI<P>By mid-'01 I was pretty much ready for production. I became a member of NAMM and had my first show this time last year. Well, there's another company in existence called Summit Audio and they had a **** fit. I was blessed with a cease and desist order and was forced to rename my company and completely reorganize. There went 6 months right down the toilet. So now I'm Zwengel Amplifiers. I dare somebody to trademark that mess!<P>So, here are a few of Zwengel Amplifiers firsts;<BR>First to open source a design on the net<BR>First ultra gain point to point amp<BR>First use of vintage/modern remote channel switching<BR>First to use a new circuit topology not based on a vintage amp.<P>There's a few others but it's splitting hairs so I won't even go there.
