Yamaha BB1100s Repair Help

[sbrag]

I've just managed to bugger my yamaha bb110d that has been my go to bass for over 30 years. I've somehow snapped off the active/passive switch and am now getting no sound. Does anyone know if this is an easy enought fix or can recommend someone good with electrics/preamps in the Bristol area.  Thanks

Simple-ish...

Got a pic of the inside the control cavity?

2 Position Switch, Couple of Quid...

Thanks Paul. That's what I was hoping. I've just put it away but will take a pick in the morning. Just had a look. Lots of wires as PJ with 3 band active EQ with passive volume and tone with an active/passive switch and 3 way pickup selector.

Steve at Hawker Repairs has done some really good work for me before, including a really complicated repair on my Dingwall after the strap button screw sheared off insite the top horn. Give him a call and see what he says.

But yes, if you're ok with soldering, it shouldn't be a big job. Take the switch out, and put a picture up here and someone will be able advise what you need to buy.

Thanks. Was thinking of Steve Hawker. Will drop him a line.

Looks like it's mounted on some kind of small circuit board.  This will either make it extra easy, or extra difficult.  Hopefully on the easy side - you just need to get the right switch, remove the old one from the board, solder in the new one, job's a good 'un.  No fiddly wires to wire directly to the switch.

 

In times like these, I make a circuit diagram before I start (just the area I'm working on, not the whole thing!) - noting wire colours and tracing where they're connected to, lest I break one off during the removal process.

Thanks all for your help. I've realised it's more than want to take on myself so hopefully Steve Hawker will be able to sort it next week.
