I've owned several Ricks over the years. Each one has played and sounded very different to the last. RIC's quality control is disgraceful.
I've owned my current 4003 for coming up to 2 years and it's the nicest one I've had - no dodgy QC issues, consistent tone, defined E string.
Outside of a custom job, there is NOTHING that sounds like them. People will say a Fender Jazz or Peavey T40 do but they don't really. The thing with a Rick is they are very fussy with regard to what amp you use. I've seen people in guitar shops excitedly asking to try out a 4003, getting plugged into the nearest TC Electronic combo and scratching their heads at the tone. If you're expecting that Roger Glover sound, that won't happen without either a big old valve head or an effect of some sort. I use various Tech 21 preamps and it loves them all.
I don't particulary like the ergonomics, and replaced the original bridge with a Hipshot so setups aren't a pain now.
In spite of all that, I am thinking of selling it as the neck has a very 'unique' (odd) profile and is starting to feel like a bit of a lump to me now and it's always on my mind when I'm playing.
