I have a 75 4001. I love it. It rips, but it also has that super clear low Rics are known for. I've played Rics since forever - 35 years now. I previously owned a stripped and custom painted 4003. The previous owner was a biker. The neck pickup was removed and a skull was there in it's place. I removed the skull and had the pickup put back in. As a result of all these crazy customizations, it had no pickup cover and it was a dream to play. I've been playing the 4001 since about 2013. It's easily the most dependable, smooth playing bass I've played, and I find I can do anything with it sound wise. But, that pickup cover really gets in my way. I play with both a pick and fingers, and either way, it's IN the way. I tampered with removal at one point and noticed the whole pickup enclosure was starting to come out, so of course I reversed the process. Any ideas on how to remove, should I try it myself and does it affect the sound? Appreciate any feedback. Thanks folks.
Which, in case you're wondering, is exactly the same pickup cover as the one on your 4001...

Personally, I like the covers on mine. My '73 4001 still had it's original cover on it when I bought it. It's beat up, dinged up appearance matches the rest of the bass, so I just left it on. My very rare (and maybe unique) left handed 2001 COY Rick 4003 came to me apparently never played - but without it's pickup cover. A quick trip to the Boutique section of RIC's website fixed that problem...
Does it affect the sound? Well... as a retired Civil Engineer with many years in Materials testing labs, I have to say that -
yes, the pickup cover does affect the sound. Every variable in a test affects the results. The next question you should ask is "How much does it affect the sound?" The answer to that one is... "Not enough for human ears to tell". The reason the cover is there, is - according to the former CEO, John Hall - to shield that single coil pickup from electronic interference. Which seems plausible on it's face; except that it's just a piece of plastic with the thinnest possible coating of copper and chrome plating - and does nothing for the
other single coil pickup. The real reason for that cover, is simply to mimic the appearance of the original "horseshoe" bridge pickups, that were standard on Rick basses until early 1973 (yeah, I just missed that - mine was made in October...

). The current cover most likely provides no more electronic noise protection than it affects the sound. Measurable in a lab - maybe; but undetectable to the human ear. So...
Bottom line? Take it off if you want; other than leaving a big hole that begs to be covered with something, it won't make any real difference. Personally, I always play my Rick's the between the pickups, so the cover is a nice hand rest. And, just to improve the look, I painted a thin, flat black strip down the middle of the cover; looks even more like the original horseshoe pickup...
