You have a Rickenbacker - how does it compare? What are the similarities? What are the differences? Does it sound similar?
Good question! The only way they are at all similar is in looks, IMO.
First of all... sound... It doesn't sound anything like a Ric. It's got more of a scooped sound. When you dig in it can sound a bit Wal-ish clicky-twangy (don't read too much into that) and can sound more like a Jazz bass than a P-Bass. I don't know exactly how it sits in a live mix yet as it'll be a few days until I rehearse with it. I'll try to post a video at some point after I get more comfortable with it and not too shy to do so.
I do NOT play at all like this ridiculously skilled person but here's a good video of what the tone sounds like in more of a flat setting.
This guy's model is fan-fretted and it has Aguilar pickups as opposed to the Bartolinis that mine came with. Still, from my experience so far, I think it's still a good representation of the overall sound, even with the Barts. I do find that I can get a nice classic rock tone as well when I put it through my Darkglass Vintage Microtubes pedal... that really thickens it up... so I do think it's pretty versatile if you get intimate with the onboard preamp settings and put it through a pedal or two.
As for playability....
It feels completely different from a Ric. It has 24 frets and a VERY flat radius, which I like. The action is ridiculously low. There's a touch of fret buzz but very little. The neck is thin and not a glossy finish so it's very smooth and quick to move around on. No neck dive. (Though my Ric doesn't have any neck dive either). The pickup locations provide a really comfortable thumb resting place.
It's really just a completely different beast than a Ric. I have an attachment to my 4003S as well, but I've always felt like a Ric is its own instrument. There's a bass guitar. Then there's a Ric. Know what I mean?
