The JTM 68 MKII borrows its features from the 50 watt Plexi Marshall with diode rectification from 1968. It comes with a classic ECC83 preamp and as is standard on all Gladius amps, the unique Variac power reduction. Of course, it is hand-wired and equipped only with the best components. An indispensable extra feature is the channel-patch, through which both inputs (treble & normal) can be interconnected without having to use a conventional patch cable (input normal hi). With an AB switch however, all other inputs can be applied separately. The Rhythm & Lead can be switched by a foot pedal which, in rhythm mode keeps even the fattest Les Paul clean and generates in lead mode the original singing heavy rock tone. By switching from lead to rhythm (hence the foot switch connection) the amplification is reduced to such an extent that the amp turns 'clean' without the slightest loss of volume or even definition. In rhythm mode you can play the amp real tight, without getting the usual sludgy sound when playing a Humbucker-guitar, (an often criticized aspect of vintage amps). In combination with the Gladius cabinets, the amp can be played clean even at a level of 1 watt without loss of sound (also at high gain level).
With the rhythm-lead function (clearly visible through different colors on the pilot light) as well as with the two different inputs, you get 4 completely different sounds!
As the name already suggests, in this setting the complete vintage sound up to 1968 is covered. It is extremely fat, round and smacky in response with heavy distortion as used by Billy Gibbons, Jimmy Hendrix and Jeff Beck.
With this setting you will get a clean and very stable tone similar to a Plexi 100, open however, without the vintage character. This channel is explosively quick in response, without sounding harsh; fat and round but mercilessly defined, like with Eddie van Halen, or Joe Bonamassa, Slash and many others.
