With the CTM-15 15-watt EL84 Tube Bass Head, Ashdown reintroduces a favorite back into the bass head ecosystem. From growling, overdriven bass to big, fat clean tones, the CTM-15 will cover all your basses. The secret ingredient? Two EL84 tube amps that sing with a beautifully rich tone. You can quickly push this low-wattage powerhouse into a state of overdrive without destroying the venue’s structural integrity. Unlike the CTM-15 that graced the world before, this CTM-15 features an onboard line-level DI that makes it great for the studio and a headphone output for silent use. At only 15 watts, this tube bass head sounds deceptively massive in the best way imaginable.

The heart of your tone





A squadron of topflight bassists has long favored the Ashdown CTM (Classic Tube Magnifier) series of bass amplifiers. And despite its small footprint, the CTM-15 sounds like a much bigger beast. Packed with two EL84 tube amps, the CTM-15 exudes that sought-after Ashdown tone. From authoritative lows to glorious overdriven break-ups, these tubes are all power.





4- and 8-ohm speaker outputs





Two rear-panel speaker output jacks ? 4 ohms and 8 ohms ? are provided on the Ashdown CTM-15 (only one can be used at a given time), the jack being chosen to match the impedance of the cabinet combination in use.





Where the magic happens





Chances are you’re familiar with Ashdown’s VU meters. These helpful output visualizations are beloved by bassists around Sweetwater. A quick glance at the VU meter takes the guesswork out of driving your amp to the sweet spot. Instead, you’ll have an accurate display of your current level so you can rock the stage and studio like never before.
