"Just checked and VTB1's are pretty cheap right now, FWIW
I think it's a real nice preamp for the price
I haven't even begun to experiment with switching the tube, which some say makes it even better."
Ditto on the VTB1. I like to run my Studio Projects T3 through it, which is a tube mic- so I'm running through
two tubes into my interface. You can never have too many tubes.
