+1 to Kwesi's bass skills.
I find that I pick up instruments fairly quickly. I know how to play a bunch of different instruments. Nothing virtuoso status, but I can definitely play in a band and play out with most of it and hold my own in most musical settings. I'm not that great on theory but I'm slowly working to rectify that.
I play bass, guitar, lapsteel, banjo, mandolin, violin, cello, and upright with varying levels of proficiency. I also play harmonica and okarina (however you spell it) from time to time but not exactly serious about it. I learned how to play uke in an evening at a friend's house. By the time the beers after dinner had opened I was already taking requests. But it was a uke...
Read on if you feel like reading my musical history. I'm bored and sick which means lot of time to post on TB.
Bass is my main instrument simply because I enjoy it the most. I've been playing 11 years now, most of it live. I don't slap, tap, or do anything really fancy but I got great feel and rhythm. I mean, I suspect I do because I've been playing out for about 9 years now and have never been turned away from a gig. I usually get a call back to play again and play around 100 shows a year with various bands. I went to the International G2G last year and everyone there was leagues above me playing wise, but I probably play out more than most of them.
Mandolin is my second most played instrument. I'm a pretty proficient mandolin player. Not that there are many mandolin players in my neck of the woods to compare me too!

I learned it last year in a month to do a St. Patty's band. We did pretty well and packed out the dozen or so shows we played. We doing it again this year too and I've only gotten better.
I picked up banjo a few months ago. I can jam with people comfortably but not enough were I'd want to play out live. I consider "live" status the ability to play drunk and have it not turn into a train wreck. It didn't take me long to figure out, but the frailing clawhammer style I decided to do has taken some getting used to. Now its just adjusting myself to G tuning and the tiny string spacing.
Recently picked up guitar and lap steel at the same time. I tune the lapsteel to open D so I can do one finger chords so I guess I'm not "really" learning how to play. Guitar is a bit of a process simply being I never really pick it up and the finger picking pattern is weird compared to bass and banjo.
Picked up upright a few years ago. I got onboard with that relatively quickly and felt I got around better on that than electric. Totally different feel and vibe that I connected to a lot more.
Violin I picked up 3 years ago. I started messing around on it for a few months and suddenly I realized I was playing songs by ear. Switched to cello when I felt I outgrew it and was having trouble getting around the fretboard with my sausage fingers. I can still pick it up and play fiddle tunes.
The only thing I haven't been able to pick up is percussion. Why?
