Roscoe Club

I'm curious about the practice of running a ground up to the bridge. As I recall (seems like I use that phrase more often these days) it was considered a "have to" on passive instruments.

The only Roscoe surgery I've taken part in was an older LG 2005 and the bridge wasn't grounded. Is the importance dependant on the type preamp, or some other factor?

What's the straight skinny ?

Hey JohnnyR! I think that bass was originally equipped with EMG PU's which don't utilize a bridge ground. Whoever installed the Bassline P/U's must have forgotten to run a bridge ground. Although I'm thinking that when I installed the new Bart preamp in that bass there was one ..... or maybe I ran one? At any rate, I don't remember it having ground issues.
 
Probably not MAJOR surgery . . . more like removing the current preamp and installing a 2-band (V,V, B/T stack, T). Same amount of holes. I just don't want to mess with a good thing as it sounds pretty spectacular the way it is. :)

Well, "more major" surgery then. ;)

You could send it back to us for a AGV (master volume/push-pull, blend, passive tone, stacked treble/bass boost control) if you were really wanting to get some good options happening......just sayin'....

And there we go, Joe you keep this up, we may have to put you on the payroll! ;)

EMG's don't need the grounding at all, they're completely isolated electronically, and the 200x series basses were all EMG-equipped, thus no ground wire to the bridge. :)

I've been curious about other pickups (like Big Singles or Dual Coils) in my LG3004 but with the angled pickups, I don't think the pole pieces would line up. Anyone try these?

Fred, it can be done, but you have to custom order them from Nordstrand to work correctly.

I had a pretty long email exchange with the guys at Nordstrand about this and while true for the 5 and 6 strings (custom spacing required for Roscoe as their standard is 19 mm) the angle of the LG pickups is not an issue as far as they are concerned so you should be good with 4 string Big Singles or Big Splits. Dual coils are not going to line up with the angle no matter how you do it - I know at least one TBer has done it, but it's "not recommended" for best results.

Speaking of the AGV option, since he has a 3004 with the soapbar routs, the Aguilar Super Singles would fit and probably sound killer in that implementation. They're not really an option on the 5 strings due to spacing and the fact that Aguilar isn't set up to do custom pickups. I would love to order a Roscoe 4 with Aguilar Super Singles and OBP-1.

I picked one up in the classifieds and it arrived today. Beautiful, light and sounds nice but the B string is a good 1/8 inch off the 12th fret. The B saddle is all the way down. There seems to be a touch too much relief but I don't have a 9/64 hex wrench at home and it didn't come with one. It's about .024 at the 8th fret when pressing down on the 1st and 17th. Not sure that a slight bit less will have a major impact on the action.

So...what does one consider low action to be on a century standard? My cheap ibby btb is 3/32 on the B and I thought that was still a little high. Am I off base here?
 
I'd definitely get a 9/64" wrench and get that neck closer to straight, the string should be lower than you're describing. That said, we do not have a "spec" that it should get to, just "get the neck almost perfectly straight, then lower the strings until they buzz, and go up until it goes away". Someone else may have a "number" to share, but the official setup from the factory is "as low as we can get it without buzzing".
