Proudly built in the UK, the Classic Series is Ashdown's flagship bass amp range. This Klystron 500 Bass Head, like the rest of the Classics are about doing everything better ” more volume, more dynamics, an extended frequency range, and greater versatility.

The 575-Watt Klystron 500 head features a single input that is switchable for passive and active instruments with a blend of solid state and dual triode tube preamp stages. 3 straightforward rotary tone controls provide 20dB of cut and boost at 60Hz, 660Hz and 5kHz, and are supplemented by 2 pairs of additional sliders giving 15dB cut and boost at 180Hz, 340Hz, 1.3kHz and 2.6kHz. A built-in dual band compressor acts separately on the high and low frequency components of the signal to provide precise control, while the on-board sub-harmonic generator turns the Classic head into a powerhouse of tone.

The inclusion of a 4-way footswitch as standard makes every Ashdown Classic bass amplifier head among the most versatile live performance bass amps in the business, providing control over the compressor, sub-harmonic generator, tube grind and EQ pre-shape.
