    It also probably won't work until there's a pin from a cable plugged in the jack there.
    +10 for the bits of guitar still screwed to it

      Well, there are two wires plus the ground coming from the jack - I didn't have a battery so I hooked up to a wall wart with a 9v adapter and tempo'ed a saddle with the rod on a CBG and gave it a go - real bad hum so I guess I'm not out of the woods yet.

        Did you get any sound from the piezo or just hum? The wall wart may be introducing the hum - a battery wouldn't have this problem.

          Might have flipped the phase on the power too, remember this is direct current. Because the (-) side is sent thru the ground side of the jack for switching it off, I imagine putting the battery in backwards (which you cannot normally do because of the keyed form factor) would create howls for sure....

            Yeah, I'm hoping it is because of the wall wart - but I don't have a battery right now - when I switch polarity it doesn't work (no led).

            It seems to work, just very loud hum along with the amplification - I'll search around for a battery.

            Thanx all.

              try flipping the phase from this wall wart if you can, maybe a huge improvement ;)

                Do you mean that I should turn the wall wart around ??  It has a polarity switch that when I switch the polarity the EQ doesn't work at all. I'm not sure I'm understanding the terminology.

                  Well I wouldn't turn it around in the wall socket, that's dangerous..
                  But maybe clip the low voltage wires coming out and flip em yeah...

                  A lot of the ones I have interchangable connectors for the end, and they can be connected up to the adaptor in Either phase just by turning that connector over..

                    I think the unit works fine - most of my problems were self inflicted - crappy amp, bare spots on the piezo rod, too close to the amp - all that "just testing" stuff.

                    Thanx for all the help - when left to my own devises I always think I'm getting somewhere ... then the smoke and sparks ...

                    Isn't that what the little switch on the wall wart that changes polarity does ??
