I am playing a small show this weekend and trying to avoid dragging my 4x10 cabinet across town. My PF-350 head has an XLR line out port so my question is can I just use the head without the cabinet, much like a sansamp? I think with that setup I should be able to pick up the sound in the...

possible to get some more pics? thanks

are the tone and volume knobs missing?

Sorry about the mislabeling, I did indeed reverse the tone and volume pots. The capacitor is on pot that was incorrectly labeled volume. Switching the black wire over to the lug with the other ground wires worked beautifully. I've got the J and mixed positions back and they sound great. I...

Thanks for all the help so far! I wanted to have a record of how things are wired up now before I go in and start moving stuff around so here's my rough attempt at a wiring diagram. It may provide some more clues as to what's going on.

Here are pics of the pickup selector wiring. Everything looks solid but I may have misplaced a wire. Also I've totally lost my J (it's no longer audible in the mixed position) and my P pickup has started crackling some. I checked the cables and wiggled the jack but nothing made a difference...

I'll try to get some pics of the wiring this afternoon. Turns out the P pickup is actually still coming through in the mixed position. It's just so quiet I didn't notice it at first. So the problem has to be with the J pickup wiring. Hopefully the pictures will give a clue.

Thanks, it is indeed a passive bass so I got it wired up and the P pickup sounds great. However, somehow I lost my J pickup and the P/J mixed position along the way. I checked the connections on the pickup selector and they look good. Could the new jack have anything to do with losing the J...

I'm trying to install a new jack in a Yamaha BB414. I thought it was a mono jack so that's what I bought but now that I've pulled the bad jack out I see there are two prongs on the existing jack (left) and only one on the new (right). Can I still use this part and just soder the second wire to...

still around?

I don't have a stereo at my apt right now, but I do have my ampeg pf-350 and swr 4x10. I was wondering if it would hurt the amp to run my laptop through it so I can play CDs and such. Obviously I wouldn't be cranking it too loud, I guess I was just wondering more about the effect of the high...
