There are a handful of famous tube guitar amplifiers: Fender tweed Deluxe and Bassman; Marshall JTM45; Vox AC30; Fender Deluxe Reverb and Twin Reverb. They’re considered icons, the best of their breed. I don’t build clones of those amps – who needs another tweed Bassman? Modern solid-state amplifiers make use of modeling or digital technology more on that later and can be made for low-cost overseas and offer a wide variety of features, but none have attained the icon status of the great amps of the 1950s and ’60s.
“Hollow-state” technology is non-linear in its response, i.e. how a preamp tube responds- in frequency response, dynamic range, distortion, and amplification -varies depending upon the instantaneous input signal. When you realize that live electric guitar signals are nothing like the waveform-generated signals of a workbench, you also can visualize why creating a musical signal that can replicate this instantaneous harmonic distortion and non-linear response is quite unrealistic, and must depend upon approximations and false assumptions. A modeling amp can sound “sorta” like a vintage amp, at least until you play it side-by-side with a real vintage amp under real live musical situations.
The tube amplifiers that I build are designed to re-introduce these vintage circuit characteristics and combine them with modern quality components, build techniques, grounding techniques, and electrical principles to produce a guitar amplifier that creates a new sound that still seems “vintage” in quality. While I might base my designs around the tweed amps circuits, compared to them I utilize a preamp that operates under higher clean headroom conditions, which both provides a means of highlighting output distortion and makes my amps very pedal friendly, something that wasn’t even considered in the late 1950s or early ’60s. Changes such as voltage and filtering levels, and a low TSR index create a larger input dynamic ranges, reduced third order harmonics and wider input dynamic range at the phase splitter. The resulting sound is what you expect from a hand-built tube guitar amplifier- sweet, dynamic, touch sensitive tones that make your guitar sing.
While my amps are not clones, they’re certainly inspired by those great amps, but with a few good modern touches, all built by hand in Austin, Texas. Maybe that’s why one happy owner recently replaced his famous British amp with a Texas Tone 12.
