From the vendor
This one is for the bassists. And the doomy guitarists. And everyone else who likes to get heavy. This is a Jfet bass preamp that sounds good itself but really shines when you engage the boost and drive it into thick, woolly distortion.
DISCLAIMER!!!!!!: Don't let the name mislead you! This has nothing to do with the beloved Sunn 200s. It is designed after a schematic on the internet claiming it is a Jfet version of the preamp of said amp but it is actually a bass preamp that was probably designed by the great and powerful deadastronaut. We learn: Don't believe everything you read on the internet! But I am pretty sure that you Sunn-Lovers will totally enjoy the heavyness that this device is producing.
