Ashdown BTA 400 with 2×15 Cab – Black: With six KT88 output tubes and a combination of ECC83, ECC82, and ECC99 preamp tubes for a rich, dynamic tone, the Ashdown BTA 400 is a powerful 400-watt all-tube bass amplifier head. It has a sub-harmonic generator, a variable valve drive for heavy overdrive to subtle warmth, a one-knob compressor, and Ashdown’s adaptable ABM preamp with a comprehensive EQ (rotary controls plus sliders). This all-black setup is a true powerhouse for any stage, delivering massive, earth-shattering low-end and powerful, classic valve tone when paired with a 2×15″ cabinet (such as the Ashdown ABM 215, rated at 800W, 4 ohms).
