Fender boner p plus?
 

I have fender p bass with a p/j pickup config but I recently saw a fender boner p bass ( I need one!!) does any one have a wiring diagram or could anyone help me put one together, it's a master vol, pbx tone, 3 way sel switch and a series/parallel switch. Thanks in advance

Here is you diagram.

You mean TBX?
You can't use a normal tone pot for this - but you can buy the Fender TBX control in / via a music store.

Instead of the p/p you can also use a DPDT switch and a 3 way lever instead of the On/Z/On switch ...

The PDF is in German - but you will surely understand!
It's very easy ...

Thanks, much appreciated
