RM-5 is a purely hand-crafted ribbon microphone, featuring hand-made and individually tuned ribbon motor with a 2" ribbon made of highest quality Japanese 2.5 micron thick aluminum foil.

US-made output transformer with Q80 nickel core is used for minimum distortion and premium signal clarity. Signal level to output impedance balance is optimal to allow using the microphone with most of reasonable quality budget preamps.

Body is locally machined of fine grade stainless steel tubing with attention to all the details and mechanically matt-polished for its signature appearance. The final assembly is performed by well trained technician, each microphone is individually tested in both laboratory and studio environments.

Good Sub-$500 Ribbon Mic For Electric Guitar?

Always liked the samples from the NoHype Audio LRM-2 (or LRM-1) with or without Lundahl upgrades and the Cascade Vin-Jet (with or without Lundahl upgrade). Also heard great things about the SE X1r and thee DIYRE (Bumblebee) RM-5.
