1966 Rickenbacker 4005

Nice Bass & a great deal! My ’65 still has the cap & I think about bypassing it now & again I really need to get the electronics cleaned I’ll try it then I guess I really think I should also try some Flats on it as well,
Enjoy your '05!!
 
I guess my question earlier in the thread has gotten over looked... so I'll try again...
Can anyone please tell me what the small knob on the control plate does?
Thanks,

Fishheadjoe

As mentioned above, it is a "blend" knob, but what it really does is act as a second volume control for the neck pickup but it does not cut off the pickup fully when fully CC (it works in reverse to a "normal" volume control) as the third lug that would usually be grounded is not connected to anything.

My former 4005WB had a Rick-O-Sound jack in place of the 5th [DEL]element[/DEL] knob. And, the .0047µF cap was already replaced with a piece of wire when I got the bass in 1973. I'd recommend anyone with a 4005 to do the same. :cool:
