Good evening ape, Thanks for your appreciation of my XB-120, by the description of your pots and switch, I could say that your XB-400 is surely an introductory year (1994) model. It probably share the same electronics and wiring pathway as for the predecessor Mercury Series MB-4 and I think that psp742 got the same bass as your. He just post not the Washburn Club thread of TB and told me that he will post the picture of his bass internal bay as soon as he gonna fix a problem with Photobucket. He didn't write if he will post on basschat.co.uk or on TalkBass (TB). I keep you in touch if your not also on TB.

You're welcome! As I told write yesterday, psp742 got one and is really a nice guy, he surely help you. Me I don't have an XB-400 because I got and XB-120 that got the same pups and preamp but not the same control knobs setup as the XB-120 got a push and pull active knob that I prefer over the XB-400, so the wiring is surely not the same as on the XB-400. Here is my XB-120:

Hi Ape! There was a Vintage Washburn web site where they put wiring diagram for all the vintage Washburn basses and guitars but it's now closed (since two weeks ago), too bad. It happened in the past and the web site come back in line after a few weeks but I don't know if it will be the same this time. [b][url="http://vintagewashburn.com/index.html"]Here is the link just in case[/url][/b], but I got another solution as there is a [b][url="http://www.talkbass.com/threads/the-official-washburn-club-part-3.1060572/page-262#post-18295402"]Washburn Club[/url][/b] on TalkBass and there is a member who own an XB-400, he's a real nice guy (psp742) and he surely will help you. Good luck!
