The "Easy B-Bender" system by Dietrich Parts

      Replacement tailpiece for electric guitars


Assembly and operating instructions for the EASY B-BENDER system

Remove all the strings from your guitar

Remove the existing stop tailpiece

Position the Easy B-Bender ( EBB) at the position of the original tailpiece

When the EBB is plugged in, all guitar strings are inserted from behind through the holes in the EBB tailpiece and, for the B string, insert through the hole in the rocker of the lever. Tune your Strings up to pitch. As with all new guitar strings, it takes a while for the string material to stretch and become tunable.

To adjust the interval of the B-bender,

Note : The bender is preset to a narrow tone interval (B bend to C #). If the interval is not exactly right (use a chromatic tuner for this!). You can adjust using the fine tuning screw. To decrease the tuning pitch, turn the screw a little clockwise. To increase the tuning pitch, turn the screw just a little counter-clockwise. Do not remove the washers as by removing the washers it will prevent EBB to achieve desired interval bends of ½ or whole tone. It will take a while until the interval is set exactly and the tuning remains stable. Once the EBB has been optimally fixed, there is little need for readjustment.

If you do not have a chromatic tuner then follow this method

tune the guitar as usual to the preferred tuning (standard tuning: E/A/D/G/B/E )

TUNING TIP: If you desire for a whole tone bend. Tune all strings in standard pitch. Fret the D note on B string 3rd fret. Sound this note then depress the Easy B-Bender trem ( Lever ) arm all the way down then sound the high E string. Both notes should sound in unison. If not then repeat the process and adjust the fine tuning screw of the B string. If you desire half step bends repeat the process above but start from the Eb note on the B string 4th fret.

If the EBB tailpiece moves a little when bending, the tailpiece can be fixed more stably by screwing one of the tailpiece screws in towards the body and unscrewing the other screw out of the body.

If you want to play with the guitar without using the EBB, you can simply place the lever counterclockwise over the tailpiece. So you can play the guitar without the EBB getting in the way.

If the lever of the EBB is used very frequently, the lever may loosen a little. To tighten the lever, please use the small open-end wrench and screwdriver from the tool set. The screw on which the lever can be moved should be screwed in tight as far as it will go. You can use the open-end wrench to tighten the lock nut and counter the screw with the screwdriver.

For a more comfortable feeling on the palm of your hand that is used for depressing the lever, you should attach the strip of foam rubber to the tip of the lever. Simply peel the film off the underside of the foam rubber and stick it on the lever.

There are still some spare parts such as felt pads and washers included should they ever wear out you can replace. The washers are color coded for easy reference. If parts of the EBB are lost or further replacement is necessary, please contact Dietrich Parts or the distributor in your region.


Have fun with the Easy B-Bender and the new possibilities on guitars with tailpiece hardware!

Hey Sven, I have the String Butler installed and I love it. There is a vast improvement to the tuning when I use my trem system. I will spread the word to my fellow musicians. I also run a guitar repair shop so I will recommend this to anyone with tuning issues. Thanks
