About This Listing

RockScience Custom Shop Upgraded and Modified MXL 550 (and 551)
The MXL550 in this "ensemble" has been totally gutted and rebuilt.  The Small Diaphragm MXL Capsule has been replaced with a k-47 style LDC capsule and our own Schoeps Style Circuit. This is not just an upgrade service. This price includes the mic! Not only that, but the 551 (SDC) comes along for the ride with a case and mic clips!

The K47 style capsule in the 550 gives this mic a beautiful smooth midrange and clean top-end without being hyped or harsh. With our low noise custom transformerless circuitry, It's fantastic on close up male or female vocals, guitar amps and acoustic instruments. It's got a very full low end as well if you would like to try the "U47 on the Kickdrum" thing. The pattern is fixed Cardioid. Our circuit is designed to work perfectly over a wide range of Phantom Power Voltages. We use ultra-low noise resistors and high quality WIMA Polypropylene Capacitors in the audio path. It all adds up to a very sweet sounding mic for an amazing price.

The 551 SDC mic is stock and unmodified. 

Both mics are in Mint condition with no dings in the finish or dents in the headbasket.

The original "Ensemble" carrying case is included as well as the stock MXL mic clips for both mics. 

If you have a low cost (or broken) MXL or other mic you would like modified, I have several options available depending on the mic. Contact me for more info and a quote.
