The Class A Tube Rectifier amplifier marks our first foray into the world of the all-tube guitar amps powered by pure Class A power amp. Known for it’s unbelievably natural, round and rich guitar sound with great 2nd harmonic overtones when cranked-up, but without any usual harshness inevitably accompanying the overdrived Class AB power section, this amp’s Class A power stage follows what was allways considered as a pinnacle of the guitar tone.

The C.A.T.R. amp is powered by the 5AR4 tube rectifier and features a 30 Watts Class A tube power amp, which on the first sight could seem a little low - but make no fools, when cranked up, then - thanks to it’s brilliant tone, spectral balance and dynamics - you would promptly start to consider this beast to be at least 60-70 Watts of ordinary Class AB power.

The preamp of the C.A.T.R. amp is equipped with a modified version of the CLEAN channel you can find in our most popular HG 100/2 MkII and HG 50/2 MkII amps together with carefully reworked, mid-gain OVERDRIVE channel section designed to be the best fit for the amp’s Class A power stage. So, all the sonic qualities of those SERIES 2000 amps have been allways known for has not only been preserved, but even enhanced courtesy of the amp’s unique power stage design.

All features including fully independent channel circuits, dual EQ, tube driven, switchable FX LOOP etc. were also kept intact so this amp is not a cut-down version in any way, but actually a real enhancement of our product line.

If you should try this amp, be prepared to be really surprised!
