Studio Projects C1 Circuit Upgrade Kit

This circuit mod kit will give your Studio Projects C1 the same frequency response curve as a $3300 Neumann U87 -- although with fuller bass! Better still, the high-frequency response of the circuit is adjustable, so you can dial in as much filtering/attenuation as you like. This DIY electronics kit requires soldering (and desoldering). If you lack the patience, time, tools, or confidence to modify your microphone, see the "C1 Mod Service" section at the bottom of this page. Because this mic upgrade requires de-soldering components from a Chinese-sourced PCB, we recommend using solder wick rather than a vacuum pump. We sell small spools of solder wick. Features & Benefits Makes your C1 sound very close to a U87... ...but with better low-frequency response. Reduce microphonics. Raise output level and sensitivity. Reduce self-noise.
