Hi Dave:

Yes, that's the one. I used one between my guitar to bass synthesizer. It was MUCH

more satisfying to find the cause of the ground loop (a silly designer used the
hardware of a rotary switch to carry GROUND from one side of a PCB to the other...
This ALSO carried the ground to the chassis via the shaft touching the edge of the
front panel... sort of a "part-time" ground.).

When I removed the Ebtech I noticed that the bass had improved a lot. So I guess I
agree with your review.

Well... except the part about "preferring the hummmm...."

Bullshit. The hum must DIE !!!!!     ;^P
