Just added a Creation Audio Labs MK.4.23 Clean Boost to my already excessive pedal board. (actually, beside the board, next to the ISP Deimator) It has 0-24 dB of very clean, quiet boost. Been thinking about adding some sort of boost to the chain, Xotic Bass RC Boost was the front runner, but I found this one for $138, vs. $186 for the Xotic. Gotta say, it does as advertised. Just thought I'd mention it if anyone else was interested in such a device. Also, the 2 pedals that sit next to my board are both shiny chrome, very sexy.
