I had a Rickenbacker 4001 back in the 80s; it was a '76 Azureglo that I bought in NYC on the street in Manhattan that had all the big music shops (47th?). Anyway, I played it in a cover band for a few years, but eventually tired of it and sold it. It had fret buzz on the 5th fret and I could never get the neck adjusted right to get rid of it. Plus the neck had a narrow jazz nut width which I don't prefer and it was a very thin neck front to back, which I also don't like. The finish seemed rather flimsy to me, it would flake off in places without being hit or dinged. Also the tone, while good for some music, seem to lack bottom end.
Anyway, fast forward to 2014. I just got a 2014 Ric 4003! Granted it is the honeymoon period, but it seems like a much better bass to me. Nut with is 1 11/16" which is just right for me and the neck is thicker front to back. The tone in the regular mode, while characteristically Ric, seems full and bassy while retaining the top end. That is, until you pull out the knob to get the vintage tone - that's the thin tone I remember. I won't be using that feature, but I dig it with the switch in. The pickups soloed give really usable distinct tones. I generally like the neck pickup on 2 pickup basses, but on the 4003 the bridge pickup soloed is trebly and funky without being too clangy.
I wonder if any of you have experience like this? Do you think the 4003 is better than the 4001? Anyway, here are a few pics from the dealer:
The dealer (Island Music Co. in Maryland - selling on ebay as imc direct) had the lefty 4003s in Jetglo, Fireglo, and Mapleglo. I thought about Fireglo, but I am a natural wood guy, and the one I got has really nice wood. It weights 9.5 lbs, which is ok with me and I think decent for a solid maple bass. One thing I will probably change is to take off the pickup cover - it looks cool but is in the way.
