Aristotelean logic dictated that I at least try out the Xotic BB preamp with the DG30, as I've been searching for something elusive with the amp. So I picked one up, and I agree that it's a really good match for the DG30. I've wanted something transparent enough to clearly hear the tone of the guitar, open sounding, etc. But at the same time, I've wanted a pedal that warms up at various gain levels. Of the pedals I've tried, the BB works best with the DG30 for what I want to accomplish. Thanks for the tip, Aristotle! The most crucial thing I picked up today in accordance with my plan to redo most of the stuff on my board is a Suhr Buffer. I won't get into the whole science of buffers too much, except to say that most of them sound outright bad. Even some of the "good ones" are artificially bright. The meh ones take away the 3 dimensionality of the signal and make it sound a little bit cardboard-y. I've been looking for a high quality buffer to serve as the sonic foundation for my pedalboard. The Suhr simply sounds like the guitar. Except unlike going without a buffer, the high end of the signal is preserved along with every other detail in what's coming out of the guitar, as it travels from your guitar's cable, through the pedals and their cables, and then through the cable from pedalboard to amp. I tested it out against the pretty good sounding buffer in the Peterson tuner (which is also a direct box, designed as such to have a decent buffer compared to most) and switching the Peterson into the chain definitely obscured some of the richness of the tone. So the Suhr buffer is highly recommended. Best one I've found yet, even more natural sounding than my old Axess buffer which was a high quality box in its day. The Peterson is now in a true bypass loop, out of the signal chain, but I can hit a button and put it into the chain for tuning. It's a keeper. Also very beautifully made of machined, anodized heavy aluminum and tiny, so it's out of the way on your board. It even has a parallel output for a tuner, second amp, or what-have-you, and a phase switch so if you run it into a second amp, both amps are in phase with one another. It's first thing on my board, so as much of the signal as possible is preserved. If I trot out a wah, I'll have it second in the chain (wahs like to interact with pickups).
