The Radiacmeter is the unholy mash-up of a Cold War era military training device and a vintage Japanese guitar pedal. Spanning tones from mild drive to ultra-compressed diode rage, the Radiacmeter works equally well on guitar, bass, synths, and more.
Based on the very first effect that designer Matthew Farrow ever sold, the Radiacmeter is our way of getting back to where it all began.
The year is 1995. Matthew Farrow purchases two unusual looking orange boxes at a flea market because they look a little bit like guitar pedals. A few months later he installs the guts of a semi-broken Japanese distortion pedal in one of the cases and starts gigging with it, until times get tough and he sells it to help make rent. Eventually, other pedals are made but the Radiacmeter remains the one that got away.
Fast-forward seventeen years. Matthew wanders into the store where he sold the Radiacmeter and finds it sitting on the counter in need of some repair. Matthew offers to fix it for the store's owner at no charge but the store closes its doors the following week and the Radiacmeter is home for good.
We hooked up the original Radiacmeter and gave it a good run-through - it's cool but not that great. Matthew and the sonic scientists at Alexander Pedals spent hours redesigning the pedal, adding a two-band tone stack and upping the output level. The new Radiacmeter can sound exactly like the original unit, but it can also do a whole lot more.
- Level: Controls the output level of the pedal.
- Sensitivity: Adjusts the gain and distortion of the pedal.
- H.F. Adjust: Passive treble control
- L.F. Adjust: Passive bass control
Tip: The H.F. Adjust and L.F. Adjust controls are highly interactive and each will respond differently depending on where the other control is set.
The Radiacmeter requires a DC power supply with a 2.1mm pin, center negative 30mA. The Radiacmeter will operate on power supply voltages up to 18V and does not use a battery. The Radiacmeter should work fine on a multi-pedal "daisy chain" connector, but if you encounter excessive noise or hum try a separate power supply.
Tip: The Radiacmeter works great at 9V but try it at 12V or 18V for increased clarity and headroom.
