A 400W hybrid head with enough range for any application.

Combining straightforward rotary tone controls with two pairs of additional EQ sliders for the more sonically sophisticated, Ashdown’s ABM preamp became an instant classic when it hit the bass world over a decade ago.

The BTA 400 (Big Tube Head) partners a third-generation ABM preamp with a 400-Watt, 8 x KT88 tube output stage for ABM sophistication with bone-crushing tube power. All the ABM features are there – EQ In/Out footswitching, variable Tube/Solid-State input stages, on-board compressor and Sub Harmonic Generator, balanced DI Output with Pre/Post EQ switching, FX loop, Tuner output and more. The BTA 400 partners perfectly with a range of Ashdown US Series cabinets.
