ah sweet success. So here are some pics of the whole thing.
First test, i took the stock Roland 13 pin cable and cut it in half, then spliced all the connections back together with phone splicers. You can see here that the left most wires are the reversed colors, brown to purple, blue to pink, and gray to orange. This cable works and i played a gig with it, with the upside down mounted gk3! woo hoo!
Here are some pics of the guitar itself, its a 2002 or 2003 js1000, look closely to see that i dremeled off part of the pickup ring to make it fit. It's sloppy work, but pick up rings are cheap and i did this while it was still on the guitar with strings on it. The ring is still damn secure in the guitar, so no worries there. Now what it looks like is the GK3 is still extended out a ways on the guitar, what you;re seeing is the small plastic riser i put on the guitar before i mounted the GK3 upside down. the GK3 does not extend past the bridge pick up ring, and is completely out of the way. soooo nice.
What i did for my main cable was order part number 0954 from the link below. Then i went to guitar center, bought a replacement roland 13 pin cable, cut one end off and put this new connector on with the reversed pin order. I was planning on having a pic of this new cable, but i left it at the bar with my rig, as we play there again next friday and saturday night. Poor planning on my part, sorry. heres the link i ordered from, part #0954 http://www.universal-radio.com/CATAL...s/dinconn.html
Now the main reason i bought the synth was for the talkbox. although it's not quite a fitting as some of the keyboards, its definitely will fit the bill with some tweaking. Here is a sample of me practicing with a song that was really easy to pick out. along with sloppy playing. You can hear some of the tracking issues i have with a super light touch on the fast notes. More than likely what i'll end up doing is use midi in and outs to an external synth for a better patch for talkboxing.
