Ceriatone · amplifier
The Ceriatone Overtone Special HRM Bluesmaster 100 is the 100-watt version of Ceriatone's hand-wired Dumble Overdrive Special clone, built with the His Royal Majesty midrange tone stack and the Bluesmaster voicing. The extra power gives a very large, three-dimensional clean channel that stays articulate at high stage volume, while the HRM overdrive produces a forward, vocal midrange with long, singing sustain and strong harmonic detail. Like the rest of the Overtone Special family it is point-to-point wired and highly responsive to pick attack and guitar volume, cleaning up as the guitar is rolled back. Its scale suits players working at band and stage volume, particularly blues, soul and fusion lead work where clean headroom matters alongside the lead voice.

“Chosen for headroom above all: at 100 watts the clean channel stays clear and dimensional where smaller amps compress, which is why it turns up on larger stages”
