An Interesting Flavor
Very interesting preamp - lots of grit of course. Sounds great on guitar as you would expect, but so far I like it most on chorus vocals to get some extra focus and energy.
I tried it on bass, (Low Impedance Break in/out > DI>Padded 5116-B), but I found the curve from clean(ish) to break up to be a little too fast so that the peaks were quite distorted while the body of the notes were not, even at around 10 o'clock with a passive bass. Hind sight, could be that it was hitting the subsequent preamp too hard. This thing adds a LOT of giddyup to the signal. Interested to try it the other way (Bass DI>636-P), but haven't gotten around to it yet.
One of my favorite parts of owning a piece like this is the pleasant surprises you get through experimentation. Sometimes you'll crank out an entire track without even noticing it.
Great work, SoundGas!

Fantastic Preamp from character to grit
I was exdcited when these were released for the 500 series rack, and got even more excited when I started using it. Great for Black Ark-like flavours, giving grit and dimension to electronic instruments, or as a deep and stromg Bass DI.
The signalflow and I/O also makes it easy to use it as a preamp in fromt of a guitar amp. It sounds special as a mic pre on drums and guitars and vocals.
I love having character gear in the rack, to use for very specific sounds or to use for those special occassions. This is all that, but somehow an all around flexible tool at the same time, that will see constant use in all kinds of sessions.
