The JAMP plug-in appears to be a guitar pedal effect due to its GUI style, but it is actually a recreation of the Marshall JTM45 guitar amp. Because this design lacks cabinet emulation, it’s best to pair it with your favorite IR or cabinet emulator.
You have controls for the tone control of this guitar amplifier (equalizer), as well as ‘High’ (stage of optimized gain and section of drive), ‘Normal’ (full-range optimized gain stage and section of drive), and ‘Out’ output control to compensate for excess level, to control all the power of the JAMP plugin.
