Title: scroll bass blueprint / measurements?
Post by: slinkp on May 20, 2015, 09:18:14 PM

Anybody got a tracing or measurements of an ampeg (or Johnson) Scroll bass body?  I'm pondering a project based on that body shape.  Thanks.

Errmm... I don't know the differences  :mrgreen:
Thanks for the offer!  I guess I better do some research before I ask for anything specific.

i will make it easier for you.   

the original AUB and AMB is the ampeg with the bridge off the body and mystery pickup.  i believe it is 34 1/2 scale.

Johnson replica AUB-2 -4 is 35 scale

AMPEG with magbnetic pickup is AMB bass.

Johnson replica is AMB -2 34 inch scale.

ONE ON FAR LEFT IS A KOREAN MADE SERIES TEN SCROLL.  BOLT ON AND MORE MAINSTREAM BODY .  DEEPER ETC.   SPORTING AND EMG J WITH LABELLA FLATS.  ACTUALLY SOUNDS PRETTY GOOD...,.,

Wowie thanks Jim!!

Okay - so NOT the SSB, that one looks really different and not appealing to me.

Is there much difference in body shape between the others?  I can't honestly tell the difference.  They all look similar, and pretty.

I'm not so concerned about pickguard, pickups, bridge type/ placement, or even the scrolls, as I wouldn't be trying to replicate any of that - just the outer shape of the body.

Has anyone attempted a Fender-Peg...?

That's sort of where I'm going with this idea. With at least one thunderbucker in it :)

I quite like that idea... :popcorn:

Yeah I've been wanting to get my hands on one of those.  I'm not generally wild about J pickups though, and certainly not with the bridge pup way back there.

If you could make copies I'd appreciate it, Jim!  I've been looking for an excuse to make a semi hollow body.

Careful Carlo, making semis can be addicting. I know!  :P

Is a scroll bass a semi? I thought it was solid with an f hole routed all the way through as a decorative touch...but what do I know, never touched one.

I think they are different designs depending on the manufacturer.  If I did one, I'd be tempted to do it as a semi-hollow body rather than routed top to back.

Same here.  I like the look but not crazy about the holes.

Hmm from the Johnson site:
"The body is hollowed out with a series of acoustic chambers that add warmth and sustain."
