Sonically, this single channel gem caters for those guitarists pursuing pure and unadulterated tonal refinement. Switching between 30 Watts Class A and 50 Watts Class A/B output alters the amp’s feel and response, with a wonderfully sensitive chime in Class A mode. In the Class A/B setting, the mids open up, for a more aggressive, full-bodied kick. The EQ section is highly responsive, and interacts brilliantly with the Gain control, going from round and smooth, to bold and snarly. The unique HF Drive control allows for fine tuning of the upper harmonics. As the HF Drive reaches 3 o’clock on the dial, it adds negative feedback at the output stage for a rich, thick overdrive which sails through any mix. A footswitchable EQ lift provides an awe-inspiring canvas for lead work, adding fullness and singing sustain. For classic British tone, it doesn’t get any better than the Custom Shop 50.
