The JTM 66 strongly reminds of the Marshall JTM 45 from 1966, its strengths are clearly in blues-rock! Equipped with a classic ECC83 pre-amp and as standard with all Gladius amps the Variac power reduction from 0,01 to 30Watts! Only the world's very best output & power transformers (aged) and state of the art tubes are applied! An indispensable extra feature is the internal Channel-Patch, switching both channels (Treble & Normal). Similar to the JTM 65, the KT 66 is used, albeit with more gain, which of course meets the requirements of blues-rock players. The guitarist who thinks the JTM 65 sounds too nice, or the JTM 67 sounds too rocky, will be very pleased with the ultimate Marshall Sound of the JTM 66!

The Rhythm-Lead function (clearly visible through different colors from the Pilot-Light) together with the two different inputs, creates 4 different sounds in one unit which can easily be switched.


As the name already suggests, in this setting the complete Vintage-Sound up to 1966 is covered. Extreme fat, round and 'smacky' in response with a lot of dynamics in the tone. The perfect Blues or Rock sound! Always defined but inclusive of all Vintage-Elements that are so important to create the right distortion.


With this setting you will get a clean and stable tone, without the - partially lively - Vintage-Character. Explosive quick in response, without sounding aggressively or too harsh. Fat and round like the Allman Brothers or Peter Green.
