Great Spector haz clone in a small package. Now both of my Spector's have one (full size and mini). I put this in a Rebop with passive Aguilar DCBs. The Rebop control cavity is very small and this fit easy. You also have the benefit of using this with active or passive, volume volume or volume blend. I don't know how he crammed this into such a small circuit. It sounds great. This is the 4th preamp I have had in this bass and the one I easily like the best.
I have seen Duff talk about how he is not really running a business, just a guy in his garage I believe he has said. I find that surprising as it was some of the best customer service I have ever seen. He is very friendly and helpful, has contacted me following up to make sure it arrived ok and if I had any questions. More of the same I have seen from him on open threads on talkbass. Thanks Duff!
