Waz's MMB-4

[ozzbike]

Caught up with Ozzie earlier today and had a good time having a chat, playing guitars, and also got around to digging out some timber in the control cavity of this build to help make the pre-amp and all it's wires fit down low enough for boomerang control plate to sit flush with body....

Thanks for helping me out yet again and loved how your MMB-5 build looks and it is coming along real good.

Cheers, Waz

You are most welcome. Thanks for bringing the coffee and pies.

I really enjoyed your five string that came along for the ride. Gave me a great insight as to what my mmb-5 will do. Thanks.

Just a query, and maybe weirdy or Simon may correct me...Your nylon bushes are keeping the pots from contacting the metal control cavity cover....and I cannot see a ground link wire running from the back of each pot to the next and then to the ground connector on your socket. Could this cause some of the issues you are having? Consider earthing everything...and it may also give you that noticeable difference between switch positions.

You are always welcome in my workshop. 🎸🎶🎼

In addition to what Waz has said above, the threaded shaft of the pot is in contact with the metal control cover, also via the nut and washer keeping the pot on tight, the pot casings themselves will all be connected together and as it looks that Waz has got at least one ground connection to the back of a pot from the photos, so all should be well. But if you haven't done it yet, then it never does any harm though to double check the ground continuity with a multi-meter, just in case.
