‘HOW TO’ INSTRUCTIONS FOR THE NEW ROLLA BASS COMING SOON

To adjust your B4 action at the bridge

Each B4 is set up with low to medium action at the workshop. If you decide to adjust your action at the bridge point, simply follow these steps to dial in your string arch as you wish. Each string has its own independent through the body bridge.

To adjust your bridge action take your supplied 5/64 allen driver.
1. Insert driver into the desired bridge hole
2. To raise the bridge turn counter clock wise
3. To lower the bridge turn clock wise
4. Adjust each one as simultaneously as possible while keeping an eye on the bridge so it is level.
5. After all your heights are set snug up all the screws.

To adjust the truss rod system

Itʼs unlikely you will need to adjust your truss rod, as it is set at the workshop and can stay locked in for years to come. On occasion during global shipping from one climate to another the neck may move on its own due to Mother Nature. If she decides to move the water molecules around in the wood simply follow these simple steps to accommodate her.

1. Take a #3 fat tip Phillips screw driver (not included) and unscrew the center plug. This is just a cover for the hole.
2. DO NOT touch the other 4 screws, they are there to keep the neck on.
3. Place your screws far to the side.

Take your 5/32 allen driver from your supplied tool kit.

4. With some good light take a peak into the hole and you will see an allen head screw about 1 inch deep.
5. Insert your driver into the hole carefully and put a little force on it as you are wiggling the driver so that you can feel it slip into the allen head. You’ll know when it slips it.
6. DO NOT turn the driver more than 1 full turn from its natural position.
7. Forward bow turn clock wise
8. Backward bow turn counter clock wise
9. Neck adjustments MUST be done while the instrument is under string tension and in tune.
10. You may have to wiggle the drive a little when pulling it out of the hole.
11. Re insert your #3 phillips screw plug and only tighten snug. DO NOT over tighten to prevent cracking the paint around the countersink hole.

REMOVING THE ROLLA BASS BRIDGE COVER (”ASHTRAY”)
(***NOTE: APPLIES TO ORIGINAL B4 BASS ONLY)

As part of our design that we love so much, we have our own custom bridge covers machined from a solid block of 6061 aluminum. They are designed to fit tightly onto the two end bridges. The two reasons you would have to remove your ashtray are: To change the strings, or you choose not to have it on at all. Generally, most players that “palm rest” their right hand while playing decide to remove the cover. Those that “thumb rest” their right hand, leave it in place. To remove it, please follow these step by step instructions very carefully to prevent any damage to the finish of your ROLLA.

A personal note from the builder—“the procedure is a little tricky the first time around.”

The cover fits over the bridges very snugly to prevent unwanted vibrations. Feel free to call for guidance if you’re having any trouble. 760-277-8781.
