Been playing my Roscoe SKB3006? since Haloween 1994 or 5, I think. Anyway approximately 120 gigs a year for 12 or 13 years and this is still by far THE coolest bass or for that matter the coolest thing I have ever owned.
I had it refretted and a new hipshot bridge installed last June.
The tech that did the work for me said he had to fill and glue three fret slots. Also to my shagrin, when we removed the old Wilkinson bridge there was a 1/2 inch diameter x 1 inch deep trough routed around the bridge mounting screw holes. I bit my lip a little and when all the Warwick, G&L and Tobias guys
stopped laughing at me,
I machined and painted a piece of 1/8 brass sheet to cover up the gaping void. Luckily the mounting holes / spacing allowed for the hipshot to be mounted.
Now don't get me wrong, I'm not complaining. When I first got the bass I called Keith to get some finish care tips and offer my accolades. He told me he had routed some body out to save weight, I thought maybe under the top wood but I digress.
I know I have one of Keith's earliest six string creations, it is mahogany body covered in cocobola everywhere. It has Barts with 2 band eq and Sperzel locking tuners (small guitar sized tuning keys). It is a neckthru model with maple, purple heart, maple laminations. The fingerboard is cocobola with oval roscoe inlays. It weighs a ton, which I like because it stays put and is perfectly balanced ( a wide padded strap has saved my C5 & C6 vertebrae).
I'm really not complaining. I love this bass as much today as I did the first five years I spent gauking at it in wonder at how anything could be this cool!!!!
I still think I got the baddest B string in the county.....state.....country................world! !! I've played all kinds of music styles and the Roscoe always fits the groove.
Fun factor 10.
Oh yeah, the laughing guys mentioned earlier were left mouth agape when I plugged in my newly reconditioned machine,
maybe that 8 cubic inches of air under the bridge makes that B string vibrate a little livelier.
Dear readers, my point is I think Keith and his people have by now got this thing down. Now I'm going forward looking into creating a new bass. Can a neckthru still be had? Seven String perhaps?
The heavier the better!
How about the Sperzels?
Sorry if I got long winded. I'll post later with a picture or two and the serial no. (when i can figure out how)
ANALOG guy in a digital world.
Old guy, old Roscoe, still awsome 
As for all those other guys laughing, just remember, a Roscoe player will ALWAYS have the last laugh.
