The Ashdown Klystron C115-500 575W 15" Bass Combo Amplifier features a single input switchable for passive and active instruments. The Klystron C115-500 also has a blend of solid state and dual triode tube preamps stages. The 3 straightforward rotary tone controls provide 20dB of cut and boost at 60Hz, 660Hz and 5kHz. 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 Klystron into a bass tone powerhouses.
The inclusion of a 4-way footswitch as standard makes the Ashdown Klystron among the most versatile live performance bass amps in the business. You have control over the compressor, sub-harmonic generator, tube grind and EQ pre-shape. Central to this bass combo amp's performance is a custom developed Neodymium speaker which incorporates a number of advanced features including: a cast aluminum chassis with thin brackets to avoid sound wave reflections, a magnet circuit with heat sink rims to ensure rapid heat dissipation and decompression holes in the cone. The result is an ultra-lightweight bass driver that just keeps getting louder as the level is increased, delivering a powerful, consistent bass tone at all volume levels and with no power loss over long performances.
