"Cascade mod in depth Unlike a standard Marshall 1959 Super Lead amplifier the Randy Rhoads model contains a modification that increases gain and therefore extra distortion within the circuit. This modification 'hot rods' the amplifier making it easier to push it into the saturation levels necessary for the sound that Randy needed. The change involves 'cascading' (feeding the output of the first stage into the input of the second stage) the two halves of tube 1. Traditionally each half would serve as input buffer/first gain stage for the two channels i.e. one half for channel 1 and the other for channel 2 from there they would separately feed the respective signals to the next stage which would mix them further amplify them and feed them to the tone stack. Cascading tube 1 results in the guitar signal being increased by around 36dB or 60 times much larger than it would normally be at this point in the circuit. Subsequent stages then try to amplify this larger signal by similar amounts and quickly run out of headroom causing the waveform to distort severely. The two channel volumes still remain functional after the modification but adopt different roles for their affect on the tone allowing control of the extra gain and volume. Plugging into channel 2 routes the guitar signal through the whole cascade circuit while plugging into channel 1 allows you to bypass the cascade and use the amp in its standard format where 'Volume 1' will function as it normally would. Standard Channel 2 format is sacrificed due to the modification."
First channel inputs are same as normal and should (in theory) sound like a 1959 (or appropriate reissue).

It has gain controls in 3 places that gives you a lot of control over how much gain is present and where.
