Thanks Loch!!

Cable modified, sent, tested, and working!
 
Another option is to replace the end of any standard cable with a stereo plug and mixing resistors. Very simple change.

Loch, thanks so much for your help in solving this issue.  You too, Dave.  Works just fine.  I guess I need to bring some extra batteries to the gig but this is much more convenient.

Great!!  Glad it's working for you!  And thanks again Loch!

Hi Jack,
 
I have the file for your bass pulled and can confirm all the details in your original post. I would insure for replacement value, and make certain your insurance provider is actually providing replacement value insurance. Sometimes an insurance company will use the price list on the website, but if you need a statement from me regarding the value, please email me your current mailing address and I will send you a document.
