just been messing round with it again today and thought id try it in my amps effects loop. It sounds great there too, gain on tap appears to be much lower, but its great for real low gain stuff, and when cranked will still sound like the gain at instrument level at bout 12-o-clock. im struggling to decide where to put it now! think im gunna stick with the crunch tone i got when it was first in chain on my board, but it works brillaintly as a valve preamp as well the eq is even more responsive (or feels it) when in the amps effect loop
