Offset Saddle Bender Mounting Instructions
You have the “new” offset saddle model design. As you can see, the front adapter requires some pretty small, fancy machining, and it operates really smoothly. I've tested it out on the offset tailpiece that I have. You also have the new fully machined handle.
Installation is easy. First you will need to swap out the saddle with the new one in your package that has the one leg with the inside edge trimmed down. You’ll need to use your own height adjustment screws from your saddle and the spring and saddle intonation adjustment screw that you have (hope you still have your tiny Allen wrench that came with your guitar).
Once you have the modified saddle in place you’re ready to put the bender on. With the long wrench I’m sending, you don’t even have to take the handle off. In fact, I suggest leaving it on for installation.
Slip the bender tailpiece slot over the tailpiece lip in the space left by the missing saddle leg and make sure to push it up against the the E string saddle (if you are using the bender on the B … if using the bender on the G, push it up against the B saddle) before you tighten the Mounting Screws. Make sure the roller tip easily goes down in between the legs of saddles so that the front roller aligns with the string path of the bridge saddle. Line it up and get it standing up straight, then hold it down tightly in place and tighten the top Mounting Screw good and tight. Then, making sure it is still straight up and down, tighten the bottom one just snugly. Then carefully retighten the top Mounting screw. Then you can give the bottom one a last quarter of a turn or so. The bottom screw is mainly there to hold the bender straight up and down. Over-tightening it can spread the mounting slot or break the mounting adapter, so do not overtighten the bottom screw.
As you can see, the string runs alongside the bender, over the rear roller, and down under the Pressure roller and back up over the bridge, perfectly lined up now.
Use the shorter “ball end” wrench to tighten the pressure roller. For best results, hold the pressure roller down with your thumb, putting just enough pressure on the string to make good contact with the bridge saddle, then, tighten the screw while holding the roller tip in place.
An occasional drop of lubricant on each roller and the bridge saddle where the string touches is recommended. I’m including some Teflon tubing to slide over the string where it goes under the “Tree Nut” on the headstock of the guitar to reduce any friction there, if needed.
Now it's time to set the pitch of your Bowden Bender. An electronic tuner is helpful in this next step: With the string stretched and in tune, flip the Adjustment Screw Lock out in a clockwise direction (looking down on it from the rear) to adjust the pitch “travel” of the Bender Handle. With the string in tune, turn the Adjustment Screw until the handle, when depressed all the way down, raises the pitch of the string to the desired pitch, usually one whole tone. Alternately release the Bender Handle, adjust the Screw, and depress the Handle to check pitch until you have reached the desired pitch. Holding the Bender Handle down while adjusting the screw will not always get you to the desired pitch. Once you have attained the desired pitch, hold the Adjustment Screw in place and tuck the Adjustment Screw Lock back under the Bender Handle, locking the Adjustment Screw. You are now INSTALLED AND READY TO GO!
Now that you have properly mounted the Bender and adjusted the pitch, you should have trouble free string bending indefinitely. Over 40 years of use by the inventor has proven that the original Bowden B Bender does not break strings. On this new model, if you have a problem with string breakage, make a note of where the string broke and advise www.bowdenbbenders.com or call 903-814-1482 if the break appears to be at the bender. If the break is not at the bender, you may need to look for a burr on the bridge saddle or a bind in the guitar nut or elsewhere and take the proper action to eliminate the bind.
ALSO NOTE: When changing strings, if you use a different gauge than the previous string, you will have to readjust the Adjustment Screw, as different gauges require different “travels” of the Bender Handle.
ADDITIONAL TIPS: An occasional drop of lubricant on the bridge saddle, the Hollow Bore Saddle Screw, the bender’s roller, the nut, and the Hinge Pin at the rear of the Bender Handle should be all the maintenance required to keep the Bender working perfectly. With heavy use, the Mounting Adapter Assembly may loosen a bit and need re-tightening. This doesn’t happen often, but keep these instructions and your Allen wrench handy in case. The mounting screws require a 3/32 Allen wrench should you ever misplace yours.
You will notice a piece of fuzzy material at the rear of the Bender Handle where it comes to rest against the Handle Rest Pin. This serves to dampen any clicking sound when releasing the Bender. If this material should deteriorate or come off, it is simply the “loop side” of self-adhesive Velcro and can be replaced by cutting a small piece to replace it, available at most hardware or fabric stores. A small pad of the same material can also be used to replace the little round “landing pad” where the Adjustment Screw touches down, should it become damaged or come off.
NOTE: There should be a slight sideways movement of the Bender Handle in the body of the Handle Assembly to assure that the Handle is not too tight. Without a string in place the Bender Handle should easily flop down into its “depressed” position. If the Bender Handle is too tight, simply take a small screw driver, ice pick, your Allen wrench or other suitable device to spread the rear of the Handle Assembly slightly apart to allow the Bender Handle to move up and down freely with no binding.
CASE STORAGE: By lightly loosening the string and pulling the handle back out of the Chevron Joint, you can lay the bender over on its side for fitting into tight cases.
