A reintroduction of a classic, Ashdown's CTM-15-U all-tube bass amp head is a low-wattage powerhouse that has a rich valve tone in a tiny package, now designed with built-in load and headphone output for silent use. With the onboard Line Level D.I., this makes the CTM-15-U a perfect studio companion.

The CTM-15-U delivers deceptively large tones from its dual EL84 power stage, and its low wattage means it’s easier to get red-blooded overdrive by driving it hard—all without shaking the foundations. 

Like all similarly equipped Ashdowns, the CTM-15's analog VU meter isn't just there for show. Giving an instant accurate display of your power amp's output the CTM-15's VU meter lets you quickly find your amp's sweet spot—where the magic really happens.

With 4-ohm and 8-ohm speaker outputs, the CTM-15-U is ready to plug into your bass cab and rock.
