The CTM 300 is housed within an 18mm marine-grade birch ply cabinet that features heavy-duty flip-style handles and an internal fan to keep things cool. Built to last, the CTM 300 uses only the finest components to keep it sounding great night after night.

Beginning with high and low inputs, for active or passive instruments, this easy-to-use amp is simple but provides a wealth of tonal options. There's a dual gain stage which means either driven or cleaner tones can be selected using the 'mellow' push button.

The 3 band EQ consists of Bass, Middle and Treble and can be sculpted even further using the 'Deep', 'Mid-Shift' and 'Bright' push buttons. This makes it quick and easy to create your own tone. A tube driven and recovered FX loop, plus a tube driven DI out are complimentary features.

The CTM 300 has a user-adjustable bias for each power tube which can be set by engaging the bias mode of the dual function VU meter on the front panel. This VU meter also monitors overall output level.

The power section of the CTM 300 consists of 6 x KY88 output tubes, providing the huge grunt, warmth and headroom bassists crave.
