All-valve tone with classic warmth

At the heart of the CTM-30 Tweed is a full valve signal path designed to deliver organic bass tone. Its 30 watt output may look modest on paper, but the four EL84 power valves provide a full and confident sound that feels dynamic and responsive. Notes bloom naturally, making this head well suited to players who enjoy touch-sensitive response. For recording sessions, this valve character translates into rich harmonic detail without needing excessive volume.

Studio-friendly features built in

This bass head is equipped with a balanced DI output that makes direct recording straightforward. The DI delivers a clean, line-level signal that captures the amp’s tonal character, helping you achieve consistent results in studio environments. With a frequency response spanning 30 Hz to 16 kHz, the CTM-30 Tweed covers the full bass range comfortably. It is a practical choice for players who want reliable valve tone without complex routing or extra equipment.

Interactive EQ for practical tone shaping

The passive Bass, Middle, and Treble controls form an interactive EQ section that encourages hands-on adjustment. Alongside these rotary controls, Bass Shift, Mid Shift, and Bright switches expand the tonal range, making it easier to dial in classic warmth or a more forward, defined sound. The passive circuit responds musically across its range, rewarding careful adjustments and allowing you to shape your tone to suit different basses and playing approaches.

Designed for flexible rig integration

For live use and pedal setups, the CTM-30 Tweed includes a front-mounted valve-driven effects loop. The valve-recovered return helps maintain tonal consistency when using external effects, keeping the signal clear and controlled. Speaker outputs for 4 Ohm and 8 Ohm cabinets offer flexibility when pairing with different enclosures. Combined with its compact size and tweed finish, this head fits comfortably into a range of setups while delivering dependable all-valve performance.
