well after i discovered the klon eats batteries as fast as a digital delay unit... i was going,.. well no more 9V there!! but now i was just wondering. i don't like to try to solder the tip he included with the klon to solder to a boss adapter. but i have a ehx adapter i used some time ago laying around. its jack fits into the klon and it is 9V. but i am not sure about that positive and negative thing on this thing!! could you help me out? i was quite risky and just tried it out and it worked perfectly. but before i will do any harm to this unit i wanna hear your thoughts!
