Powered by a pair of EL84 output valves with an ECC83 preamp valve, it offers classic valve warmth and natural overdrive alongside a simple passive Bass, Middle and Treble EQ.
Features include Ashdownâs analogue VU meter, transformer-derived balanced DI, 4Ω and 8Ω speaker outputs, plus a built-in load and headphone output for silent operation.
