Hey, bygoneguy - just noticed you were in my home town (actually, I'm in Pointe-Claire). WOW! Where can you find a Ric for a grand in Montreal??? When I pull out my Ric here, people act like they've seen a unicorn, you just don't find Rics around town so if you can get it for $900... well, I'm in tears.
Good luck with the 4001. I actually took a big gamble and bought a 4003 Ric off of ebay for $1500. Very risky, but the seller had a good reputation. And I wasn't disappointed.
It was modded with a Seymour Duncan as the bridge pup. At first I was concerned about not getting the Ric sound, but the S/D pickup roars. So I'm not bothered by the mod because getting it back to stock is very straightforward and I'm having fun with it now.
I use medium to heavy gauge strings, and apparently my 2004 4003 has a neck that can take those easily. I have heard that the 4001's could be fussy when you strayed away from the stock gauge strings.
