Tube sound for training and recording! The CTM-15 head delivers surprisingly wide tones thanks to its dual power stage using EL84 tubes. Its low wattage makes it easy to achieve a natural overdrive by pushing the head to its limits without undermining your sound. Whether you're looking for clean, fat tones or rumbling, saturated bass, the CTM-15 is sure to amaze you! Like all Ashdown heads, this one features the famous analog VU meter. It's not just a gadget that lets you instantly visualize the output level of your power amp, the CTM-15's VU meter lets you quickly find the "sweet spot" - where the magic really happens. Equipped with 4- and 8-ohm speaker outputs, a DI output and a headphone output, the CTM-15 is ready to give your bass the typical tube sound, whether in the studio or at rehearsal.
