Based on the hugely successful MAG range but with a little more bang for your buck, the Toneman range by Ashdown Engineering is exclusively available via our friends at Thomann…

Powerful EQ

At the heart of the TM 600H head lies a feature-packed bass preamp with rotary bass, middle and treble controls, along with supplementary rotary controls providing 15dB of cut and boost at 220Hz and 1.6kHz.

Tone shaping

Additionally, front panel push switches for Bright and Deep settings provide instant access to attacking and warm, rounded sounds respectively and, on the subject of low-end response, the trademark Ashdown sub-harmonic generator is ready and able to deliver truck loads of earth moving tone if called upon.

Kick it in

With the Toneman also includes a built-in compressor with precision sonic control. Along with tube emulated drive control for that extra bit of grind with your tone.

Powerhouse performance

Fueled by a potent 600W power section, TM 600H head features inputs for active and passive instruments, along with an effects send and return, a tuner/line output and a balanced DI output for direct connection to a mixing console.
