SGD 2-Band Preamp. New

SGD Preamp

This is our first preamp offering. It's a very musical 2-band preamp based on a '76 Music Man Stingray. It's a faithful recreation using the original LM4250 - Programmable Operational Amplifier IC as on the original. I also use high quality metal film resistors, polyester film and tantalum capacitors, and quality Bourns potentiometers and Neutrik jacks. Pots have 1/4" shafts. Hand assembled, it comes fully wired and tested, ready to drop in to your Music Man or other bass, or even a stomp box case for an external preamp. Please note that preamps are built to order, and are not in stock items. But this also allows customizing. I can do custom configurations. Please note: there are no refunds on custom work.

Preamp operates with a single 9V battery and current consumption is around 250 µA. That's MICRO Amps!

"All I can say is WOW, what an awesome sounding preamp. I A/B'd it with my MM Cutless and dead on it except yours is quieter." - Greg T.
