What This Bar Actually Does
I have been using a Dan Electro S Guitar Bar on three different Strats over the last two years, switching between hardtail bridges and Fender-style synchronized tremolo systems. It is a replacement vibrato arm assembly, not a full bridge. The main point of it is the mounting system and the damping block design. Most players who buy this are looking to replace a worn-out original arm or add a shorter break angle to their tremolo setup. The Dan Electro S Guitar Bar itself uses a 10mm threaded post with a standard Fender hex nut on the back. The pivot point is slightly wider than stock, which matters more than you might think for tuning stability during aggressive dive bombs. I went through three different brands before trying this one, and the difference came down to the knurling on the grip and the smoothness of the pivot action.
Getting a Dan Electro S Guitar Bar to Work Right
The installation is straightforward but there is one detail most people miss. The spring tension on the back side needs to be adjusted after mounting, not before. If you tension the springs first and then install the bar, you will either overtighten the post or leave it too loose. Remove the old arm, note how many springs are engaged, clean the cavity of any debris, insert the new post through the bridge plate, and thread the nut on the back with a thin washer between the nut and the plate. Finger tight first, then use a spanner. Do not overtighten the nut. I learned this the hard way when the brass threads on my bridge plate stripped on a 1982 reissue. The arm angle is adjustable via a set screw on the pivot collar. Start with the arm pointing straight down at a ninety degree angle from the body, then tighten the set screw just enough to hold it in place without crushing the aluminum collar. A quarter turn past finger tight is usually enough. If you over-torque this, the arm will stick when you try to push or pull it, which defeats the whole purpose. Tuning stability with this bar depends heavily on your nut condition. If your nut slots are worn or improperly cut, no bar upgrade will fix your tuning issues. I had a situation where my guitar would go sharp after every tremolo use, and it turned out the nut was the problem, not the bar. Replacing the nut with a TUSQ unit solved it completely. The bar itself does not cause tuning drift if installed correctly.
Real-World Issues I Have Encountered
The pivot mechanism on the Dan Electro S Guitar Bar uses a small brass bushing that can develop play over time, especially if you use the bar frequently. After about eight months of regular use, I noticed a slight rattle when the bar was not in contact with the strings. The fix was simpler than expected. A tiny drop of light machine oil on the bushing surface eliminated the play entirely. Do not use WD-40. It evaporates and attracts dust, which makes the problem worse within a few weeks. Another issue is string height interference. If your bridge saddles are set very low, the bar arm can contact the strings when you push the tremolo down past a certain point. I solved this by raising the bridge plate by two turns on the spring posts, which gave me about three millimeters of additional clearance. You lose a small amount of pull-up range, but you gain the ability to dive without hitting the strings. The knurling on the grip is adequate but not exceptional. If you play with sweaty hands or in hot conditions, the arm can slip during use. I replaced the stock grip with a silicone sleeve, which cost about four dollars and made a noticeable difference. It is not required, but it helps.

Compatibility Notes
The Dan Electro S Guitar Bar is designed for standard Fender S-type tremolo systems. It fits most Stratocaster-style bridges from the major manufacturers. It will not work on a Wilkinson or a Floyd Rose without modification, and attempting to force it will damage the bridge plate. If you have a non-Fender tremolo, check the thread diameter and post length before ordering. The standard specification is M10 x 28mm post length with a 10mm head diameter, but some aftermarket bridges use slightly different dimensions. For Telecaster bridge conversions, the bar requires an additional mounting bracket. This is not included with the Dan Electro S Guitar Bar, so factor that into your order if you are doing a swap. The bracket is relatively inexpensive and easy to install with basic tools.
When Not to Use It
If you primarily play clean or light compression tones and rarely use the tremolo arm, upgrading to this bar is unnecessary. The stock Fender arm performs adequately for occasional use. The Dan Electro S Guitar Bar shines when you are using heavier tremolo techniques, such as full dive bombs or rapid pitch modulation. If your playing style does not involve those techniques, you are spending money on something you will rarely use. Similarly, if your guitar has a locking nut or a high-end aftermarket tremolo system like a Bigsby or a Gotoh GE1996, the Dan Electro S Guitar Bar is not the right upgrade path. Stick with manufacturer-recommended parts for those systems. Mixing components from different manufacturers can introduce alignment and stability problems that are difficult to diagnose.
Price and Availability
The bar typically retails between thirty and fifty dollars depending on the finish and vendor. Third-party sellers on eBay and Amazon sometimes list it at higher prices, so check multiple sources before purchasing. The direct manufacturer channels tend to have the most consistent quality control, though delivery times can vary. Replacement parts are available separately, including the pivot bushing, the set screw, and the grip sleeve. Having a spare bushing on hand is useful if you plan to use the bar extensively, since it is a wear item. The set screw is also a good spare, as stripping it is a common failure point if you overtighten during installation. I have not encountered any significant manufacturing defects in the bars I have owned, but I have seen reports of inconsistent thread pitch on cheaper copies. Make sure you are purchasing from a reputable source and avoid the lowest-priced options, as the machining quality directly affects the smoothness of the pivot action.
