PEDULLA OWNER’S MANUAL

This version of the Pedulla Owners Manual was updated in 2012 and refers to electronics and other materials used at this time.

Trussrod adjustments explained herein apply to all basses made in late 1989 and after. Pedulla guitars that were made between 1975 and mid-1989 have a truss rod that requires a 5/16” nut driver to adjust. It adjusts the opposite direction of the newer models explained within. (If your bass was made in 1989 and you are unsure if your bass has the older or newer truss rod, contact us with the model and serial number of your bass for information.)

Basic care and much of the other information contained herein applies to all Pedulla bass guitars, regardless of when they were made.

We take great care in the making of our instruments and have pride in our work. If, after reviewing the information contained herein, you have any questions, comments, or concerns, please feel free to contact us.

PICKUPS AND ELECTRONICS
 

Standard Active Electronics - MVP/Buzz and Nuance:
The control panel consists of a volume, pickup pan, treble +/-15 db, and bass +/-15db, plus midrange control. The system offers maximum versatility with minimum clutter.

The midrange is controlled by a boost/cut mini-toggle switch with a variable output, adjustable from within the electronics cavity.

The pickup pan control acts as a pickup blend selector. Turn the pan fully clockwise for fingerboard p/u only, to the center position (where you feel the “notch” or detent) for both on equally, and fully counterclockwise for bridge p/u only. The space between these positions is used to blend the p/u’s in any combination. The volume knob will adjust the overall output of the blend.

Clockwise from center will boost treble or bass up to 15 db and counterclockwise will cut up to 15db. The center position is flat.

Note: setting treble and bass controls at maximum boost could result in excessive noise or distortion from overdriving the amplifier.
Also: cutting too much midrange from the tone at the amplifier may reduce growl.

 

 

 

 

Standard Active Electronics - Thunderbass and Thunderbolt and Rapture
The control panel consists of volume, p/u blend, treble +/-15 db, and bass +/-15db. The active tone system also features two low noise buffers. Clockwise from center will boost treble or bass up to 15db and counterclockwise will cut up to 15db. The center position is flat. The Thunderbass and Thunderbolt include two proprietary “Thundersound” modules. The “Thunderguts” circuit is controlled by a mini-toggle and accesses a thicker character with a tight, articulate low end and midrange.                                    

 

The Rapture RBJ2 and RBPJ controls consist of volume, p/u blend, treble and bass +/- 15db. The single pickup Rapture (RB) comes has an added low mid boost switch.

 

Battery
All our active systems are powered by one 9V battery which is turned on when the plug is inserted into the output jack. When the bass is not in use, disconnect the plug for longer battery life. A 9V alkaline battery will last for 1 month of continuous use (more like 6 months to a year in real-life use). A weak or dying battery will result in a distorted output.
The Rapture and Nuance have a quick-access battery compartment. To change the battery in any of the other models, remove the four screws holding the back plate, and replace. When reinstalling the back plate do not over tighten screws.

ADJUSTMENTS
Your “action”, or the way your bass plays and sounds, is dependent upon the strings, neck “bow”, bridge height, pickup height, and intonation. Understanding their interaction is important in maintaining the performance of your Pedulla instrument. Once your instrument is properly set up, the only adjustments needed will be the truss rod and intonation. Always start the tune-up by checking and adjusting the neck first See “Neck Adjustment” below.

STRINGS
Your fretted bass came equipped with stainless round wound strings. Our fretless basses have round wound nickel gauges. Do not attempt to use steel strings on the fretless models, as they are too harsh on the fingerboard and won’t sound so great. Your Pedulla bass was made with and for Pedulla Bass Strings (which can be ordered directly from this website) Original Factory Gauges are as follows:

30B

E.45

65A

80D

100

128

.C128

.100G

.0D80

.0A65

.0E45

.02B8

Different gauges and types of string vary in the amount of tension they exert on the neck. Changing gauges or brands may require neck adjustment.


NECK ADJUSTMENT
Although the fingerboard is sealed, it is still subject to changes in temperature and humidity. As humidity increase, the fingerboard absorbs moisture and expands, forcing the neck to bow away from the pull of the strings. This is most common going from winter to summer. When humidity decreases, the fingerboard releases moisture and contracts, forcing the neck towards the pull of the strings. These changes in moisture content affect only the surface cells of the fingerboard. They are small and easily adjustable either by you or a qualified repair tech. 
Your bass is equipped with a special dual action truss rod which differs from conventional systems in that it engages in either direction, and will adjust the neck in both directions, independent of string tension. We have enclosed a special
trussrod wrench with your instrument. Be sure to keep it with your instrument as you or your repair tech will need it to make adjustments. Attempting adjustment without the proper tool (or using the tool improperly) may result in damage to the truss rod.

Ideally, your neck should be adjusted perfectly straight with only the slightest relief. If you hold down an outer string at both the first and 22nd fret, the distance from the top of the 7th fret to the bottom of the string you are holding should be no more than the thickness of a thin pick. Too much relief in the neck will make for very mushy action in the intermediate region of the neck. A back bow in the neck will cause the lower frets (toward the head) to buzz. Besides affecting playability, neck adjustment has a profound effect on the tone, especially with the BUZZ basses.
Note: all neck adjustments should be done with the strings tuned to pitch.

To obtain the best growl from BUZZ basses, the neck should be adjusted very straight (no forward bow) and the pickups should be adjusted as close to the strings as possible without getting hit when played. Also on BUZZ basses: the most accurate intonation is achieved by fingering the note so that the fleshy part (or leading edge) of the finger is directly on the fretline; the “bulk” of your finger will be behind the line. The fretless growl comes primarily from the bridge pickup.

If the neck is bowed backward (away from the pull of the strings), turn the truss rod clockwise and this will force the neck forward. See diagram below.
manual_diag102

If the neck is bowed forward (with the pull of the strings), turn the truss-rod counterclockwise and it will pull the neck back. See diagram below.
manual_diag202

After the neck is adjusted to the desired line, the action should be adjusted at the bridge.
manual_diag302

Please note: Regular truss rod adjustment is required to maintain the optimal performance and longevity of your Pedulla bass.

 


BRIDGE ADJUSTMENT AND INTONATION
After your neck has been adjusted, set the action (bridge saddle height) at the bridge using the wrench provided with the instrument. This will vary according to your playing style and personal preference. An average action will have the treble strings about 1/16” from the 21st fret and the bass side 3/32” from the 21st fret (measured from top of fret to bottom of string), and should generally follow the radius of the fingerboard.

Once the neck and bridge adjustments are set, intonation should be checked. This is best done with a tuner. Tune the harmonic on the 12th fret. Then fret the string at the 12th fret (just behind the fret with normal playing pressure). If the fretted note is sharp to the harmonic, adjust the bridge saddle towards the back of the bridge. If it is flat, the saddle will need to move towards the pickups.

Fretless intonation is set in the same fashion. After harmonic is tuned, use a thin, stiff edge (such as a credit card) and push the string to the fingerboard with the card edge, directly over the 12th fret marker. The lines in your fingerboard are exactly where the frets would be.

PICKUP ADJUSTMENT
PJ and JJ: Push the outer strings down on the 24th fret and adjust the pickups as close to the string as possible, without contacting the string. If they are too close, the string will clunk when you play, if they are too far away the resulting sound will be weak and thin.
 

SB: The soapbar pickups needs to be a bit further from the string and should be adjusted about 1/8”from the string.

 

These measurements are approximate and should be measured from the top of the pickup to the bottom of the string.

FINGERBOARD CARE
The coating on a Buzz fretless ebony fingerboard is polyester. We suggest using a nickel wound string as it is less abrasive on the finish. After playing, clean it by wiping it down with a soft, clean, dry, cloth. You will find that the finish will scratch or mark. This is normal and will not affect the playability of the bass. With normal
wear and tear, this finish will usually last 2 to 6 yrs or more, at which time it will simply need recoating. It is time to re-coat when the finish actually wears through to the fingerboard or stray rattles occur.

If you have a Rapture or Thunderbolt with a maple fingerboard, it is coated. To clean, simply wipe down with a soft, clean, dry cloth after each playing.
 
For all other models, with uncoated fingerboards: Each time you change your strings you should clean and oil the fingerboard with products and instructions supplied with the
Pedulla Fingerboard Care Kit. This helps maintain the stability of the neck by slowing moisture travel to and from the surface of the fingerboard.

GENERAL CARE & TIPS
Keep your bass in adjustment! You’ll play better, sound better, and maintain the performance edge and longevity of your bass.

To realize the full potential of your Pedulla bass, use the best bass amp and cabinet possible. Our pickups and electronics are amongst the finest in the world and are made to respond in frequencies that are not reproduced by many middle and lower end amps and cabs. We highly recommend using Pedulla Bass Strings, which were specifically designed to bring out the best in your Pedulla bass guitar. 
 

For basses with polyester finish (excludes ET Thunderbass & ETB Thunderbolt & Nuance that does not have the optional gloss finish): Cleaning and polishing can be done with the products supplied with the Pedulla Polish Care Kit. This will remove all grime and glaze any small scratches. Do not use any “guitar polishes” that contain wax or polymers. These only build up on top of the finish and are not as durable or lustrous as the polyester itself.

For basses without polyester finish
(such as the ET Thunderbass & ETB Thunderbolt & Nuance that have standard satin finish): Cleaning and waxing can be done products supplied with the
Pedulla ET Care Kit.

You can substantially increase the life of your strings by wiping them down after each playing.

When changing string gauge, you may need to readjust the truss rod for lost or gained tension.

It is best to replace your battery every six months. Always keep a spare battery and screwdriver in your case for emergency battery replacement.

When not in use, your Pedulla bass should be kept in the case, and stored away from heat supplies, air conditioners or humid basements. Any extreme changes in temperature and humidity can adversely affect the instrument. These changes can be made more gradual by leaving the bass in the case.
