D'Addario 9V DC Adaptor for Pedals, etc.

This adaptor is brand new, never used. It is DC 9V 800mA, with filtered output for low noise. It is tip (inside) negative, sleeve (outside) positive, as are pedals. For use with all kinds of pedals for guitar, bass, synth (not just D'Addario). Bought for $17.99 a couple of years ago, selling for $10.
