Yeah. I first tested it at the builder's house, through a Ibanez practice bass amp, with a Squier Bullet.
It was goddamn awful but the builder insisted I had to try it where it's meant to be; in front of some tubes.
It rocks that way. But I'm quite sure it doesn't just boost the volume, the SHO.
It's not a LPB-1 and it's not a Boss GE-7 with the volume slider up.
It does something funky to the dynamics, it does something with the electricity itself. It's not just a bass push or a mid hump or whatever.
It's something else, and it's goddamn brilliant.
