Holy crap has this thread grown since I saw it last! Let's talk some more about Ricks!
Lot's to mention. My Rickenbacker is a black, or I should say Jetglow, '79 4001. The original white pickguard was smashed into pieces when the bass fell over one day (I know it hurts to think about it. It was my stupid guitarist. I made the mistake of leaving it at his house. On my way with him to his house to go jam, "Uh...Brian. Did I mention your bass? Uh...") but all is well now with its custom black-white-black pickguard in its place. So it's all black on the body except for the white body binding and the thin white outline of the pickguard. It looks awesome. I still haven't replaced the original white nameplate though. It would look better with a black one, but a new one wouldn't say "Model 4001 - Made in USA" on it!
First regarding the Rick-O-Sound stereo output. I built myself a great cable for it using two mono cables and a big fat stereo jack. One cable was strait and the other was coiled so I fed the strait one through the center of the coiled one and taped them together every couple feet. Both cables fit into the stereo jack and the other end terminated in two mono 1/4" jacks. Sweet.
The original bridge pickup on mine eventually developed a broken winding in it somewhere and we couldn't fix it without rewinding the pickup. So... I took that opportunity to have a pair of Bartolini Rick replacement pickups installed. World Of Difference! It still sounds like a Rick, only a lot nicer. The black Barts look really cool in my black bass too. I'd definitely recomend them.
Regarding the cap-bypass mod, I'm really not sure if that was done along with the pickup change or not. I don't remember. So I'm going to have to open it up and check it out. If that cap is still in there, out it comes!
Some were saying they always had the tone controls decked. I always found that I got a better tone with both controls backed off some. I have mine set with the bass tone set back about 4 numbers and the treble tone about two. Warmer sound.
I've always used roundwound strings on my Rick. Rotosounds were the only strings on it ever until just recently when I started using DRs. But they have taken their toll on the frets big time. The frets on my Rick are so badly beaten, bruised, and just plain worn out, it sucks. The intonation is flawed as a result, which is why I don't use it as much anymore. I know I can and should get a refret job done, but that is major surgery for a Rick with its bound neck and laquered fretboard. So I've been hesitant to get that done. I know I guy who did the job on another Rick. I watched its progress. It took a very long time putting coat after coat of clear on the fretboard to get it back to original shape.
I had often considered replacing the bridge and doing a Geddy Lee job on it, but could never bring myself to hack it like that. The rubber mute on mine is so rotted out it's nearly useless now. I'm sure it could sound better with a new bridge but then it just wouldn't be the same bass anymore.
Speaking of that mute, did you know that Bartolini makes a special stacked humbucker pickup that can be installed in place of the string mute!? That means you'll have a third pickup that can be used to dial in just the right amount of high-end twang. Being that close to the bridge it's got to sound wicked. I've thought about getting that installed on mine.
The next step in the evolution of my Rick is to install a Bartolini active preamp. The output of my Rick, even with the new Bart pickups, is still pretty low. With the preamp in it, I could get its output up high enough to compete with my Zon. At the same time I'd probably install a completely new wiring harness with new pots and jacks. I've heard that makes a big difference for old Ricks.
That Rickenbacker has been with me for 15 years. It'll be mine for life!

P.S. Can you tell I like talking about my Rickenbacker?
