This is one of the later ones with the 48v phantom power, (I used to use it with the XLR input on my Markbass head, worked great.) This was once used on a pedalboard and has some slight adhesive on the back, (I did my best with a goo be gone pen.) I also put 4 replacement rubber pads on the bottom. $50 shipped CONUS for a decent "set it and forget it" pedal. Paypal is preferred.
