Ultra-Phonix HRM recreates the much sought after Dumble™ HRM overdrive tone that pushed the tweaked Overdrive Special Amplifier into stardom. Amongst the limited amount of ODS amplifiers produced by the legendary amp maker, a handful were armed with EL-34 power amp tubes rather than the 6L6 tubes found in most ODS amps.  This gives the HRM edition of the Ultraphonix a quintessentially British voicing and EQ shift compared to the original version. The “Master” control determines the total output of the pedal. The “Volume” control adjusts how hard the pedal’s preamp is working, giving you more control over the amount of gain coming from the preamp. Turn up the “Accent” control to increase presence and slowly introduce more saturation into your signal. The “Ratio” control allows you to blend your distorted and clean signal, and the “Tone” knob allows you to accentuate different upper-mid frequencies, ranging from 800-1.6k Hz.

Another winner! Just got this baby from Vertex and had a gig the same day! So put it to work right away, and she's inspired me at first try. This was in a small jazz club with volume restriction, but even at low volume into a clean amp, this pedal has all the sustain, tone and great touch sensitivity. I now own the Steel String, the Ultra Phonix and the HRM and they cover the whole territory!
