Our first production model... 2 years later.
When we completed our first production run in 2013, we thought we had nailed something really special... and we had, but that didn't mean we would stop there.
We took our 55/75 amplifier and kept the same output transformer and preamp circuit but coupled it with a set of Genalex KT77s and a redesigned power transformer. On top of that we re-voiced the preamp for slightly less gain, but opened up the phase inverter to push the KT77s quicker. The idea being we could increase the overall dynamic response of the amp but also increase the power tube distortion.
The preamp is reminiscent of the famed "V-Series" amplifiers produced in the late 60's, including the toroidal inductor based active midrange circuit, which gives this amps it's extreme versatility on stage or in the studio. Want that classic "blackface" clean sound? Dial back the 1kHz. Want that british mid push? Boost the 3kHz. With up to +/- 12dB of midrange control, at three different frequencies, you can change the entire feel of the amp on one knob. The input sensitivity switch changes the AC gain of the first stage which gives greater control over headroom, but also control over how the amp responds to effects pedals. Bass and treble controls both have a very wide range of function giving you even more control over the tonality of the amp.
Control panel differs from the older model in the photo.
