Ashdown Engineering - 100w Tube Bass Head

Like it's big brother, the CTM-300, our CTM-100 takes it's sonic cues from the classic valve heads of the past and pairs its 100W all-valve design with modern features, construction and reliability.

Built tough for life on the road
Built tough, the CTM-100 head 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. This is an amplifier that is built to last using only the finest components to ensure years of trouble-free performance night after night.

Classic all-valve tone
With a classic five valve preamp configuration and a fully-loaded power section consisting of 2 x KT88 output valves, the CTM-100 is easily up to the job of delivering its powerful tones at small to medium-sized gigs night after night.

Flexible tone shaping
From mellow '60s bass tone to growling '70s-style bass, straight through to thick and powerful modern tone, the CTM-100 covers a huge range of sonic ground. Hit the Mellow button to engage smooth, warm, clean tones or punch it out to dial-in pure valve overdriven growl.

Standard tone controls give you a wide range of uber-musical sounds, while Deep, Mid Shift, and Bright switches let you fine-tune your tone to the situation. The EQ section is a passive tone circuit - meaning if all controls are at zero, there will be no sound through the amp. All the controls are highly interactive, giving you the possibility to dial in exactly what tone you want. Don't be scared to dial the pots all the way to get the most from the controls.

Valve life preserver
Saving costly and time consuming trips to the Tech and keeping your amp sounding better for longer, the CTM-100 features user adjustable bias for both output valves which can be set by engaging the bias mode of the dual function VU meter on the front panel. Each output valve is individually fused and user replaceable without removing the unit from its case (meter also indicates valve or fuse failure).

Tube-driven DI & Effects Loop
To get your tone direct to the desk in the studio or on stage, the CTM-100 features a valve-driven, transformer-derived DI output with an isolated ground to deliver maximum sonic purity and consistent output night after night.

Similarly, the front-mounted effects loop is also valve-driven for maximum tonal preservation.
