I'm waiting to hear back from Mark Karan to see what he's doing with it lately. I only got his initial report where he had A/B'd it with and without and he liked what he was hearing. He also commented on the sweet top end that he could dial in with the vari-z knob. He said he had to really check it out cranked up, but his first reports were very positive. I'll chime back in when I learn more.
I've been a fan of the SIB stuff. I had an Echodrive for a while and really liked it. The Fatdrive is a real nice tube booster/EQ pedal. It's really flexible and very musical. The SGBB is unity gain, very quiet, and has no EQ or voicing in it. It's pretty much flat from about 8Hz to over 200kHz. The Echodrive is kind of a different animal, but surely offers that nice tubey mojo.
I'm still waiting to hear back from the Weir camp to learn more exactly how his rig is all wired up and exactly where the SGBB is wired in to the chain. I'll also report back with that info.
And Pete, man you're an original Black Box guy from the very early days of its inception as a pedal steel buffer. Thanks for trusting it so early on.
