I just tried this out and it sounds killer. I plug into my amp as usual and then run the preamp out from the amp into a boss blues driver and into another bass amp running an SWR 8X8. The first amp is powering a 410 and a 15. This sounds absolutely freakin' amazing. What's really nice is that when distortion is off it's really beefy and while it's on you still have the 410 and 15 pumping out quite a bit of bottom end. TRY IT OUT!!! It's really fun.
