DC Power Polarity ?

[cpcohen]

I've lost the power supply for my Wavedrum.

The Wavedrum manual specifies 9-volt DC input, but doesn't say whether the center pin is +, or -.

I have several Korg 9-volt wallwarts, but I dare not experiment.

. . . . HELP !!!!

Thanks --

Sorry, already answered in this Forum:

9 volts DC, center pin +

which matches the Korg Volca, which I have.
