    In my new place I am getting quite a bit of 60 cycle hum through my baby blue. Anyone tried the Ebtech Hum X? how well did it work?

    I keep one in my gig bag, and it helps some of the time in some noisy rooms. If the hum stops when you disconnect the cable, the HumX probably won't help; it can't prevent hum that is induced into the amp through the cable and bass.

    I used the Ebtech "Hum eliminator" to eliminate a ground-loop I had when I split my signal using a DigiTech Bass Squeeze to my amp and the PA. Worked great, but since it is designed for line-level (+4dB), it cut the volume a bit.

    If you're just pluggin' in to your amp, I don't suppose you've got a "reverse polarity" (or ground-lift?) switch on the back? Some amps do, and that solves the problem.

    there is a ground lift on the back. Doesn't seem to make any difference. Hmm, the hum can be heard without an instrument or cable attached. Maybe this won't work? who knows...

    I'd stop by Radio Shack or Home Depot and get one of those little $5 outlet testers - the 3-prong kind you plug-in with LEDs to tell you if your outlet is OK.

    I'm assuming you looked around for proximity to floresent lighting and large electric sources (transformers) already.

    I'll try yo snag the tester today. No transformers that I see around, and no suspect lighting. Funny thing my Eden wt800 doesn't seem to be doing this. Could the furman power strip be stopping it? hmm.
