1 Q: Can I use rechargeable 9-volt batteries for my guitar?

A: We do not recommend rechargeable batteries for replacement for 2 reasons: 1. they do not put out enough voltage (at least 8.4 volts) to properly run the instruments. NiCad and NiMh "9-volt" batteries, even when fully charged put out a maximum of 7.2 volts.2. Even if they did work, rechargeable batteries only hold a charge for 1-3 months. Alkaline batteries, when fresh, can go 6 months or longer. We recommend Duracell for a good fit.

2 Q: Could you tell me string height, and pickup height?

A: string height for our basses is 3/32" or 2.4mm between the bottom of the string to the top of the fret on both the E and G strings at the 12th fret. The G string can be slightly lower due to the fact that it is the smallest string. Of course, tightening or loosening the trussrod affects the bow of the neck, which is how desired action is generally best achieved.
The factory specifications for the pickup height are 6/32" or 4.76mm from the top of the plastic between the pickup covers to the bottom of the G string. The angle of the pickup is set fairly level, so the larger strings are naturally a bit closer. If you haven't already adjusted the pickup or changed to a very heavy gauge string set, you shouldn't have to do any adjustments on the pickup.

3 Q: Do I need a truss rod tool for my guitar?

A: The truss rod wheel design was designed so any musician can easily make minor adjustments to the neck. Any tool such as an allen wrench, nail, small screw driver, etc. that will fit into the wheel hole will work. Turn the wheel a quarter turn at a time then check by playing your bass. Clockwise will raise the fingerboard.

4 Q: Do I need to loosen all of the strings before making a neck relief adjustment?

A: You should make all adjustments with the strings where you would normally play them. Do not loosen the strings to adjust the truss rod.

5 Q: How do I maintain the neck on my new guitar?

A: For everyday cleaning, use a small dose of high-grade lemon oil. For the fretboard, use Ernie Ball Wonder Wipes Fretboard Conditioner。
An infrequent dose of gunstock oil will help to keep the neck maintained; we recommend and use Birchwood-Casey Tru-Oil, but any good quality gunstock oil will work. Clean neck first. Use a small amount of Tru-oil, leave it on for 5 minutes, then wipe it off with a paper towel. Then apply Birchwood-Casey Gunstock Wax. Be sure to douse the paper towel with water before disposing of it! Read the wax and oil manufacturer's instructions regarding disposal of these used paper towels.
Rosewood fingerboards should not be treated with gunstock oil; instead they should be treated with a high grade of lemon oil.
For cleaning, try using the same high grade of lemon oil to clean the entire neck, both maple and rosewood fretboards. Keep in mind that if the dirt or grease has been worked into the wood, it cannot be removed except by sanding it down, which we do not recommend unless exercised with extremely fine sandpaper (1200-1600 grit), and even then very sparingly. It is better to keep it clean in the first place. Washing your hands first helps!

6 Q: How do I set up my guitar?

A: First check relief in the neck by holding the lowest string down on the 2nd fret with your fretting (left) hand. Then, hold the same string down on the 12th fret with your plucking thumb and tap on the string in the middle to see how straight the neck is. There should be no more than the thickness of a business card between the string and the frets. If there is no relief in the neck, a little pressure in the middle of the neck (after adjusting the trussrod wheel) should help.

7 Q: How long does the battery last, and how do you know when it needs to be replaced?

A: Average battery life is 6 months. We recommend Duracell batteries as replacements mostly due to size inconsistencies between battery manufacturers. Do not leave your bass plugged in when you have finished playing, as this will drain your battery faster. Battery life of course depends on how often and how long you play. When the sound of your bass becomes distorted, it's ready for a new battery.

8 Q: If my fretless fingerboard became grooved and worn out can it be replanted or should it be replaced?

A: It can be resurfaced by sanding, and could be replaced by a professional luthier. Resurfacing the board should only be done when the wear is sufficient to cause the sound or playability of the instrument to suffer. Resurfacing too frequently will greatly reduce the useable life of the fingerboard. Usually, replacement is only necessary after several resurfacings and years of heavy use.

9 Q: Is there any coating that can be applied to protect the wood such as polyurethane, and how would this affect the sound?

A: Various epoxy and Cyanoacrylate (super glue) finishes have been used on fretless fingerboards. This tends to yield a brighter tone and may wear longer than bare wood, depending on the material used. Some such finishes do not adhere well to oily woods such as rosewood or pau ferro. Have an experienced guitar tech do the work.

10 Q: What are the differences between the StingRay and the Sterling?

A: The StingRay is more of a traditional bass with active electronics that gives players a great all-around feel and sound. It is great for any style of music.
The Sterling is a sleeker, lighter bass than the StingRay. It has a thinner neck and smaller body. The 3-way switch offers more tonal varieties, and the phantom coil offers a single-coil sound without noise.
Now both are available in dual-pickup versions. On those models, the 5-way switch functions are the same, but the main properties of each bass, including the electronics, remain different from each other.

11 Q: What happens if my instrument gets too hot, like if I forget to take it out of the car on a hot day?

A: Get the instrument into a normal temperature environment, and allow it to cool off. Don't put it in front of an air conditioner, or anywhere that will cause a drastic temperature or humidity change. DO NOT make any radical adjustments to the instrument until it cools down!
Once it has normalized, check it over. If there is no apparent damage, you're probably fine, and there is no need to worry. Just don't let it happen again.

12 Q: How does the Piezo Bridge function on the guitar?

A: The basses with the new piezo bridge option are in addition to the original pickups and electronics. The piezo may be used in conjunction with, or completely separate from, the standard configuration.
The piezo/magnetic blend is controlled by a knob that has a center d? tente position. Turn the knob all the way clockwise and there is magnetic signal only. Turn the knob all the way counter-clockwise to obtain piezo signal only. With the knob in the center detente position, there is an exact 50/50 blend of piezo and magnetic signal, and any other setting will be blended according to where the knob is set.
The piezo bridges are not available as a retrofit for earlier basses.
