Hi, I am new to this awesome wealth of knowledge. Been reading through alot of this stuff and what a great group of people. I have a question that does not seem to be answered anywhere, even in the manuals, and I feel like a total retard for asking this, but - I repaired a broken headstock on a 1974 Series I bass. The neck is repaired, but all 3 of the connection pins in the cavity were unplugged before I got it, and in checking the electronics I am having the most maddening time figuring out the 4 way switch and the pickup connections. One thing would explain the problem to a degree - did this bass originally come with a stereo to mono 1/4 cord? There is not one in the case. The 5 pin is there. The DS-5 is in the case too but does not seem to be operational. When I plug a mono cord into the jack and then into an amp and start trying to figure the correct lead to the correct output on the motherboard, I get the weirdest things happening, like the bridge pickup working ONLY when plugged into the neck pickup, or the volume for the neck pickup controlling everything, and the only thing I can think of from reading all the posts here is that I definitely need a stereo to mono 1/4 jack, but before I go buy one, or make one in my shop, I wanna make sure its not something else. And Alembic is my idol, and I have never owned one, and I feel like an idiot for not knowing this. I sent an email to Mica, but I am sure they are swamped. Can someone help me? I might have follow up questions.
