Exciting new Touch/Tap technology, which can easiliy be installed in any touch type instrument. This new technology eliminates any need for manual muting and set's the db level at over 120db down, while at the same time increases the high's and low's of your instrument by over 40%.
     Totally off at all times until you either "Touch it" or "Pick it".

     Separate volume control for each string "twice"

     Four separate Modes: Fret only"very dynamic", Six Sense"open and fret sense", Vox "threshold sense" and Garbage"everything on like a normal guitar".
     Full 3-Band EQ, for each pickup.

     Stacked pots, Volume/Pan.and so much more you must go to;
Comments by designer of the Electronic Muting system, Dave Bunker

As many people in the tap/touch world know I've dedicated my life to discovering how to make Touch Play easier and better. On my first patents of the early sixty's I used the manual "felt or other object a few inches up from the nut" to mute the strings. This worked, somewhat but always left lot's of unwanted noise and muddy notes. The Electronic mute eliminates all unwanted sounds such as hums, finger noise, slidding sounds.
     In coming weeks I will add much more to this content regarding the benefits that My Bunker Touch Guitar™ buyers and post some of there dynamic new music and sounds not only on my site but on

Great artist and studio bassist Doug Deforest

Hey Dave,

I don't know if you remember talking with me a few months ago, but you made me a pbc bass a few years back which has to date played on over 200 albums! (well, so has it's owner! LOL) I am asked CONSTANTLY about the history of this bass, and you and I talked about it in detail when I called back then. This is one of the best instruments I have ever owned, and I am now in need of a backup. I would love to be your most fervent endorsement player. You can see the bass at  and hear it on many recordings online. I am very eager to speak with you about the possiblity of even a cost deal, as I was given on the first bass. Dave, you cannot believe the sound this bass puts out on record. All I have to do is take this bass, my sans amp, go direct with no EQ, and the sound is intense. If you need to refence my exposure possiblities, you can call Jon Raney at Raney Recording at 870-668-3222. I am the house bassist there, as well as doing shows live with a host of acts including Leroy Parnell, Radney Foster, Kelly McGuire and many more. Please hit me back with info......I am VERY anxious to have a backup....I NEVER want to play another bass..........period!

Double-Locking Tremolo (Fulcrum/Knife-edge) Tuning Problems
(also applies to many Single-Locking Tremolos)

Tremolos in the past have come and gone, but, for about 25 years the Double-Locking type has dominated the guitar market. Widely considered the best type of Tremolo to have, Double-Locking Tremolos can have quirky habits. The most notorious is coming back flat after a dive-bomb or staying sharp after applying a little vibrato to a nice (or not so nice) chord.

Sound familiar? Well... Here are some things for you to check-

The Knife-edge Pivots.
These two friction points are the first place check. The best time to do this is during a routine string change. When all the strings are off the guitar remove the spring cover on the back of your guitar.  Using needle-nose pliers remove the springs from the bridge (not the “claw”), one spring at a time.

Be careful not to scratch your guitar or chip the paint when the Tremolo is free of its springs, especially be careful when removing the last spring. Now with the Tremolo removed take a very close look at the knife-edges on the body of the Tremolo. Use a magnifying glass (if you have one) and look for debris, dirt and any deformation of the knife-edges.
Most knife-edges will look a little worn, meaning the metal doesn’t appear to form clean, sharp “knife-edge” or “V” shape. That’s OK. If the “V” shape is badly worn it will look very “rounded-over” at the point of contact compared to areas just left and right of the point of contact for each pivot.
Also the (chrome, gold, etc.) plating can wear away leaving frayed bits of metal around the pivot area. Clean this area well, remove any debris with #400 wet/dry sandpaper. Be careful not to sand on the exact point of contact for each pivot, you just need to remove surrounding debris.

Now let’s look at the pivot screws on the body of the guitar. These have the opposite “V” shape machined into them. As before have a good look at them (use your magnifying glass, if you have one) and inspect the area of the “V” shape where the Tremolo made contact. You’ll notice some wear and just as before compare that worn area to adjacent areas of the “V” shape. The wear on these pivot screws should minimal, even hardly noticeable. If the wear appears to be quite noticeable you should replace your pivot screws. If that’s not possible then you can rotate the screws just a bit (about 1\4 of a turn) in either direction as to allow the contact areas of the tremolo to meet up with a lesser worn area of the pivot screw “V” shape (aka- groove).

Also check that the pivot screws are at a “right-angle” (90 degrees) compared to the face (or top) of your guitar. Sometimes the wood around the pivot screws wears out or becomes compressed in the direction that the strings and springs pull on the Tremolo. If the screws are more than slightly leaning (or tilted) you will have tuning problems. Depending on your woodworking abilities it may be best to have an experienced guitar repair tech do this repair for you.

Be sure to reassemble the pivots clean and “dry” meaning no oil or grease. Lubricants may sound like a good idea, but dust, dirt and other contaminants will eventually stick to the lubricant causing more harm than good. These pivots were engineered to operate “dry.”

If the pivots are very worn take care when adjusting your “action” or string height. The rotating of the pivot screws with the strings tuned up to pitch can cause even more severe wear on the “V” shape(s) on the Tremolo (which is much more costly to replace than the pivot screws). If the pivot screws are very worn, loosen-up the strings nearly all the way so that they’re pretty detuned and then adjust the string/action height. This is a lot of work to go through, but you’ll be far better served when your done

TENSION FREE tips and tats;
     Here in Tension Free land you must lay back and have a cool one to start, it will make your understanding far more in focus. In weeks to come we will get into great detail as to why and how Tension Free makes your AX perform the way it does.
     This segment will be called Ask Dave and I will try to answer all of your questions in a timely fashion. 
     Probably the most asked question I get on the Tension Free technology is how to adjust it. The main thing to remember in this is not to ever try to turn or adjust the pin on the down side of the neck at or close to the 17th fret. This can only be removed using a 1/16th inch allen wrench if the neck and the adjustment screw has been removed. The adjustment for the neck is on the back of the guitar or bass between the neck mounting screws. This adjustment requires a 5/32inch allen wrench to adjust. Turn Counter Clockwise for relief and Clockwise for back bow.
     For all of you tech's out there, here are a few tips to help you to perfection on Tension Free necks. If you have removed the adjustment screw and the pin mentioned above you now can pull the headstock out of the neck. It looks like a weapon now but don't get carried away. If you have a neck which has too much relief when the rod is out, bend the bar at the mid point the opposite way(back bow) with about the same bend, usually under 1/16th of an inch works although I've seen necks that required as much as 3/32 inch. Now when you put the rod back in the neck you have probably taken out the relief, if not turn the adjustment screw counter clockwise about 1/2 turn or more if needed. NOTE: when re inserting the 1/16th inch pin make sure it is centered in the neck. The pin is usually 1/2 inch deep inside the neck.
     Another thing to be sure to have in place when you re assemble your Tension Free neck is the felt strip which is between the head stock and the neck. This felt strip is important to make sure there is no vibration between neck and head stock.
