This is the second version of the Bass-Drive (not the MOSTFET version). I am the original owner and the unit is in great working condition (minor wear and missing the two front rubber feet). I have modded it for 18V (put another 9V battery in series as there is enough room, see pix). I will also include the 18V Dunlop adapter too! Running the Bass Drive on 18V gives it more headroom as stated in the Tech, Tips and Answers section of the Fulltone web site (
http://www.fulltone.com/qaframe.html). I found this to be a great overdrive for bass especially when run on 18V. I'll take $110, price includes shipping to the lower 48. Paypal preferred
