Early '90s Made In England JCM 900 50W Hi Gain Master Volume Mk III 212 combo, aka Model 2502.

This 50W amp is switchable to 25W (half power switch on the back panel) and also has dual footswitchable Master Volumes (shared EQ) which allows you to dial in the second master as a lead boost.

The oft-despised diodes are located in the second preamp control, so with the Gain Sensitivity turned off and the Preamp Volume maxed the fizziness disappears & tones enter JCM 800 territory
