The new MK IV version opens up an unprecedented power reduction with a modified „Trainwreck“ Post Phase Inverter Master Volume WITHOUT any tone loss on the back and a real Varic on the front. All tubes are now from the expensive manufacturer Mullard, which make an incredible sound difference. The most significant change is the tone harmonization in single notes (also known as Plexi Ghost Notes). These 4 elementary innovations make the biggest difference in the history of Gladius Amps.

The JTM 67 is based on the Marshall JTM50 from 1967 which started the Rock-Era of Marshall Amps.

It was the first Marshall with EL34 power tubes, but on top of that with a rectifier tube for a „SAG“ response. It comes with a classic ECC83 pre-amp and as standard to all Gladius amps with the unique Variac power reduction! Only absolute state of the art components are used as well as being hand-wired and best possible tubes. An indispensable extra feature is the Channel-Patch, switching both channels (Treble & Normal) together without having to use the conventional patch cable. Also the Rhythm-Lead switch allows you to play the amp real tight, without getting the usual sludgy sound when playing a Humbucker guitar, which is often criticized with Vintage-Amps. The JTM 67 brings enough gain for classic rock however without becoming marshy in too much gain. Despite the EL34 power tubes it keeps on producing a fat sound and makes the guitar come through genuinely unaltered with the world famous charm of the Plexi!

With the Rhythm-Lead function (Clearly visible through different colors from the Pilot-Light) as well as with the two pre-amps you get 4 completely different amps in one unit which can be even be switched!

Rhythm-Channel:

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 harshly. Fat and round similar to the Vintage Version, but mercilessly defined like with Gary Moore or Ritchie Blackmore.

Lead-Channel:

As the name already suggests, in this setting the complete Vintage-Sound up to 1967 is covered. Extremely fat, round and dirty as well as 'smacky' in response as used by AC/DC, Jimmy Page, Bernie Marsden and many others.
