The Plus versions have had very big changes: 3 position bright cap switch w/2 different caps which influence the sound immensely, Red Base Power Tubes which currently build by far the best EL34 power amps, new capacitors in the signal path, NOS pre amp tubes and much more.

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.

3-way Bright Switch

The Gladius story began with further developments of Plexi Style Marshall amps from the late 60's. It was quickly recognized that a power reduction is absolutely necessary for today's customers. In order to be able to do without the unloved master volume, Gladius specialized in the development of a self-developed VARIAC system, which comes close to the sound of a voltage-reduced amp. The Mark II was born. The Mark III then got a rhythm and lead switch, which simulates the characteristics of a 50 watt and a 100 watt Plexis (Except the JTM 65). However, this was too much of the organic crunch for many customers and they also wanted a lossless master volume. Here Gladius decided on the PPIMV modified by Ken Fisher (Trainwreck), which enables the sound to be played at room volume without the loss of dynamics and without loss of gain. The development continued, however, because many customers wanted a more mid-oriented tone that could assert itself better than the Plexi tone even in the most fragile mixes. By changing many little things, the Mark IV was brought to life, which is also clearly more rocky in the JTM 67 and JTM 68. As the last big challenge, Gladius has dedicated himself to the topic "Bright Cap". The internet is full of comments on this topic, what one loves, another hates. One thing is certain, the topic of bright caps is very sensitive, because the sound characteristics change fundamentally. So Gladius has integrated a 3 Way Bright Switch into their now available MKIV PLUS models. This means that the middle position has the previously low Bright Cap, while position 2 has an extremely high value that sounds very, very rocky. Position 1 has the most treble and has a medium value, which can be described very nicely with the sound of AC/DC. Bone dry, very tight and very cranky in attack. Why the name Plus was chosen is obvious. The amp has received more updates than ever before in the history of Gladius JTM's. In addition to the bright caps, there were completely new capacitors in the signal path. Thanks also to the people at Tube Amp Doctor who developed the new Red Base Pre- and Power-tubes, which come very, very close to the sound of old tubes. So now a JTM's over the wide range from classic Plexi tone late 60's to modern JCM 800. There are no amps on the market that are as flexible as the Gladius JTM's without the well-known signal losses. That's Rock'n'Roll Ladies & Gent's.
