Voiced like a ribbon mic Never harsh, never too bright Purpose-built for electric guitar Captures your tone with minimal effort Origin Story David Grissom and Tim Pierce had been testing the RM8 mic on cab. Both loved the tone. Neither needed the RM8's internal pattern circuitry. I commented to David that I could design a simpler, purpose-built mic for guitar cab, to recreate the tone he loved in the RM8, but make it easier to use and more accessible for guitarists. He liked the idea. (That's why I put his initials on the circuit board.) Guitar cabs represent a fairly unique application. They can be loud, so the mic would need huge amounts of headroom. The mic should have a soft top end, to eliminate harshness. The mic should work well on its own, so that artists need not manage comb filtering (phase cancellations) invariably created when two or more mics are put on the speaker. We designed a low-distortion circuit and a large-diaphragm capsule with a unique tuning. We implemented the circuit with fantastic components. The combination has beaten numerous popular mics on guitar cab, including dynamics, condensers, and ribbons.
