Washburn XB125 Stopgap Wiring Mod

Related Posts

Here's a "Crafted in China" Washburn XB125, the main squeeze of Orkestra JPN Pahang bassist Rizal Efendi. It originally had active electronics, but that died long ago and all that remains is an empty 9V battery compartment. Currently, it is fully passive, with a modified control configuration of master volume, master tone and three-way pickup selector toggle switch. 

Now, the bad news. The toggle switch stubbornly refuses to function, the bass produces no sound, Rizal has an upcoming gig, and none of the local music stores have toggle switches in stock. As the XB125 is his only bass, I need to come up with a solution in double-quick time. 

Here's what I did - I desoldered the faulty toggle switch and wired in a DiMarzio 500K pot that happened to be in my spare parts bin. So, what you are looking at below is an adequately functioning Washburn XB125 with a neck pickup volume control, bridge pickup volume control and DiMarzio 500K master tone control. Necessity is the mother of invention!

  2. That would be an interesting experiment, no doubt. It's the first time in my life that I've across such a nut.
