Paul Reed Smith’s first run of amplifiers was in the early 90s when he introduced the solid state HG70 Harmonic Generator amp. Offered in a head cabinet or 2x12 version. This is a 2x12 in excellent to mint cosmetic condition, including the original cover. It has spent its entire life sitting in a studio. Played on occasion but more often used for mood lighting-it really looks cool when turned in and lit up. I won’t comment on the virtues of a solid state amp because this is just a piece of PRS history. Only about 250 of these amp were ever built before scrapping the project and later bringing Doug Sewell on board to build proper tube amps. Includes original pedal

In the late 1980's, vacuum tubes used in guitar amps became scarce as more and more tube manufacturers ceased production. Paul Reed Smith set out to design a top-flight guitar amp using
transistor technology, and the PRS HG-70 Harmonic Generator was the result, without doubt one of the sweetest, warmest solid-state guitar amps ever made.
The Harmonic Generator's circuitry was designed primarily by Eric Pritchard, currently of Pritchard Amps, and was innovative in two key ways. First was the use of a harmonic generator that was used to add additional harmonics to the amp's basic tone to create a lively, more tube-like sound and response to playing touch. Secondly, the PRS HG-70 was one of the very few transformer output-coupled transistor amps ever designed. In essence, it actually utilizes an output transformer, much like a tube amp.
The PRS HG-70 sports two channels. "Rhythm" produces fat, rich sounding clean tones, while "Solo" yields overdriven crunch and lead tones. While the Solo channel is ideal for punchy blues leads
and fat classic rock riffing, it stops short of delivering over-the-top, max-gain metal or thrash tones.
The HG-70 is definitely geared more toward lush, vintage-flavored clean and overdrive sounds.
