hey casper, i have been getting into circuit bending recently and have found your site to be very informative. i was just wondering what type of jacks you used on this mod. i am in the process of building something similar to this and was looking into using dc power jacks but it can get quite expensive. i was also wondering about the pitch mod on the sk1.. do i have to unscrew the board and solder the points from the other side? i have found the pitch base but i havent hooked it to the + and - power supply out of fear of destroying my sk1 which i have spent much time on recently. if you could answer any of these questions id really appreciate it thanks again man! 

also if you could point me in the right direction to finding some cheap jacks that would be awesome. i looked through the sites you recommend but i am not sure of what to order lol thanks
