Rickenbacker Basses / Arnquist bridge mod
« on: May 19, 2008, 08:21:45 AM »
Here's a brilliant new (to me) Mark Arnquist bridge mod. He has kindly agreed to share the pics here.
Arnquist's description:
"As the saddle chassis tilts away from the neck ... by drilling the former screw alignment points all the way though the base.. this makes the base a holder for the screws.
Changing those screws out from 3/4" to one inch hex screws gives you all the adjustment you need.
The hex screws under the bridge in the cavity are used for the saddle chassis feet to sit in.
After the re-assembly of the bridge ..it appears as stock, the chassis remains upright and has plenty of up and down height variation.
By having a good anchor and being held upright you also get better sustain."
1. Post holes drilled through:
2. Bridge feet sit inside hex screws:
3. Feet anchors installed under bridge base:
4. Saddle chassis feet indents drilled out:
5.
6. bridge feet extend through base now:
7. Base becomes support for chassis:
8. Modded bridge re-assembled:
