The Ultraphonix 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.
The change in tubes resulted in a meatier, more
aggressive overdrive sound that resembled the
sounds of a British high-gain amplifier. We
revamped the Ultraphonix HRM’s controls, giving
you access to EL-34 gain on top of a myriad of
other tones. 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. Unlike its stock
counterpart, the Ultraphonix HRM is all bite; if you
want that cranked EL-34 Dumble™ sound, look
no further than the Ultraphonix HRM.
