Professional vs Hybrid vs X-Trem, what's the difference? Why is one so much more expensive than the other? The answer is very simple actually...
2xxx = Professional models always start with the number 2 are the most costly models in the Kahler inventory because they are 100% handcrafted in Los Angeles using union machinists and are sold only through the custom shop at Kahler International Inc. With the Pro models, you can choose different materials for different tones.
4xxx = X- Trems are built at Kahlers China facility under exact American SAE specs and exclusively for imported OEM models only. You wont be buying any of these ala cart unless its already on a guitar. They are not sold separately. Beware of anyone who sells these as new. They are never new as they are always installed first at a factory.
7xxx = The Hybrid series is the USA factory version built in the Southern California by Kahler USA, sold only through music retailers. The specs are exactly the same as the above models. The method of manufacturing is less costly due to factory labor versus hand machining.
The quality across all models is the same. Only the method and place of manufacture dictate the different costs.
I don't get the Kahler numbering system. I see names and numbers like 2200, 7300, X-Trem, Hybrid, Cam, Fulcrum...What's up? Please spell it out for me.
What's a cam? If your not sure ...Click here. The first of 4 numbers in the family hierarchy represent the location of manufacture and manner of distribution. A "2" or "3" means it is hand milled through the USA custom shop. Sold only through Kahler International Inc., it is stamped Kahler "Made in USA". It is known as the "Professional" version. A "4" means it was factory made in China under exact SAE specs for Kahler and is primarily a lower price point trem for a guitar manufacturer to use. Stamped the "X-Trem", they are not sold thru retailers. A "7" means it was factory made in the USA and is the retail version most players will see. It is stamped Kahler "USA Hybrid"... Hybrid because it incorporates a locking screw to lock it into a fixed bridge. It's a full trem and a fixed bridge in one.
The second number represents the type. Stud mounts are "2", Flat mounts are "3" and Bass bridges have a "4".
The third and fourth number can represent metal configurations or number of saddles....
For fixed bass: The third number followed by a 0, represents the number of saddles. For example, a five string fixed bass bridge is 7450. A four string would be 7440 ect. There are 2 Cam/Saddle combinations for the 7 and 8 string guitar models. The third number in those models represent the metal combination Brass/Steel "1" or Brass/Brass "2".
For 6 string guitars starting with "2", the third number in combination with the fourth, represents the Cam/Saddle metal configuration. There are 4 Cam/Roller configurations possible on 6 string handmade guitar tremolos starting with a "2". They are: Steel/Steel "00", Aluminum/Brass "10", Brass/Steel "15", Brass/Brass "20", The fixed guitar bridges (3300 and 7330) use a uni-body with brass rollers "00" & "30". Hybrids and X-Trems have a "00" for end numbers only. They come with wide spec cams and brass rollers.
Generally, The fourth number refers to the number of strings on the trem. "0" for six strings on the guitar, "5" - "6" for five and six string bass models, "7" - "8" for seven and eight string bass and guitar models. There are 2 Cam/Saddle combinations for the 7 and 8 string models, the fourth number dictates the number of strings.
Regarding the Kahler made, Floyd Rose Iic. Fulcrums...
All start with a 2. The "Traditional" line was a 2 followed by a 5. It had 2 versions, a steel roller "00" and a brass roller "20"), hence the 2 models 2500 and 2520. The next was the 27xx series made up of 3 models with no brass or steel choices. The "2700 Series" was the first of the series. It was stamped "2700 Series" but was really called the 2710 "Killer". The next was the 2720 "Spyder" followed by the 2760 "Steeler". Some optional saddle choices for the Spyder created a couple of sub-series like the 2722 and the 2750 but these were rare.
