Handmade 400 W valve bass amp head for tonal connoisseurs who crave the traditional punch of valve amplification with the added flexibility of a modern preamp. The head features an EQ In/Out footswitching, variable Tube/Solid-State input stages, on-board one-knob compressor, Sub-Harmonic Generator, balanced DI Output, FX loop, Tuner output and more. The variabile valve drive enables you to set it on zero for a pristine solid state preamp tone, or wind it up to increase the level of true valve overdrive. The ABM EQ features familiar Bass, Middle and Treble rotary controls and two pairs of additional sliders. The head also features a flexible footswitching via the FS-4 footswitch (not included), sub-Bass output and a Line Input for the connection of an external sampler or sound source. The dimensions of the amp are 362 x 610 x 300 mm and the weight 35 kg.
