The following information is the definitive guide on Floyd Rose tremolos (and variants) with a special (but not exclusive) emphasis on left-handed guitars - past and present. Nowhere else on the internet will you find all this information in one place.


This article is in five parts:



The "Korean Catalog"


These are Floyd Rose licensed tremolos that have been in regular use for the last 35 years by all major guitar brands with Korean production lines and are sometimes still in use today, even though the genuine Floyd Rose Special is the more common option for entry-level and intermediate-level guitars made in Asia today.


The appeal remains for these, especially now that the Floyd Rose Special is no longer made in Korea. The 1000-Series genuine Floyd Rose tremolos are still made in Korea and are comparable, if not equal, to the quality of the products in the Korean catalog. The original molds were personally authorized by Floyd Rose when OEM production began in the late 1980s.


The "Korean catalog" serves as a universal OEM pool for all Korean trading companies that source for buyers, and Korean factories such as Samick, Cort, Unsung, Saein, and WMIC that build the guitars. Many emerging Chinese factories also drew from this catalog from the mid 2000s and early 2010s before shifting to their own universal OEM pool.


Brands that have used or still use tremolo systems from this OEM pool are B.C. Rich, Jackson, Charvel, Ibanez, ESP, Kramer, Yamaha, Gaskell, Schecter, among others.


Sometimes they are sold in the retail market by guitar parts companies, such as Guitar Fetish, and CH Guitars, usually not left-handed. The catalog has remained unchanged for over 35 years.

Note: While these units are still manufactured with the old ‘Licensed’ stamp, this reflects original tooling and market perception—not an active licensing agreement with Floyd Rose.


FRT-50 : TRS-PRO replacement


The FRT-50 is a Takeuchi TRS-PRO clone. The block has "Licensed Under Floyd Rose Pats." on it, whereas all Takeuchi blocks have "Takeuchi" and "Made in Japan" on them. The Korean version is visually identical to the Takeuchi original but does have slightly different dimensions and sometimes is not interchangeable. New versions do not have the licensing statement on the block.


It is important not to confuse the Korean FRT-50 with late-model Takeuchi JT580LP units. After the Floyd Rose patents expired, Takeuchi baseplates did not have the licensing stamp. Neither does the FRT-50. The only identifier is the block statement.


  • Jackson: In 1995 Jackson introduced the "Performer Series" as an entry-level line which was initially produced in Japan. After 1995, production shifted from Japan to Korea and then back to Japan for the final 1998–1999 run before the series was discontinued. Those made in Japan used the original Takeuchi TRS‑PRO while those made in Korea used the FRT‑50 from the "Korean catalog." Both were designated model code JT580LP and had "Jackson" etched on the upper part of the baseplate. Forums seem to be uniformly critical of the early Korean versions. In addition to the Performer Series, some Japanese Dinky models were fitted with the Korean JT580LP through the 2000s, including this left-handed Dinky DK2L. Left-handed Performer Series guitars made with this unit include this 1999 left handed Jackson PS-4; this 2000 left handed Jackson PS-4, and this lefty Jackson PS-4.



  • ESP : This 1998 lefty ESP LTD MA-200 has the FRT-30. LTD guitars were made in Korea by World Musical Instrument Co., Saein Musical Instrument Co., Cort, and Samick at different times. We know all these factories drew from the same OEM pool.


  • Cort: This left-handed Cort Viva Gold II Series guitar, manufactured ~1998 appears to have a FRT-50. The picture is not very clear. If the owner of that guitar ever reads this, contact me.



FRT-20 : Double-locking Floyd Rose II replacement


The FRT-20 from the "Korean catalog" is a double-locking unbranded Floyd Rose II clone, complete with the hammered metal finish of the Schaller original. It is a die-cast copy complete with the appearance of replaceable knife edges at the pivot points.


Note to left handed guitarists: I have brand new stock of this unit. Complete kit with L2 nut, 36mm block and all accessories to do an immediate swap. These units are better quality than the current Floyd Rose Special. I also modify these units with stainless steel saddles, saddle screws, and saddle lock bolts, and Titanium upgrades. Check the Gaskell Guitars Retail Reverb site.


For a lefty, this is your best upgrade or restoration option for a vintage Kramer, Charvel, or Jackson that either had an original Floyd Rose II, a JT-580, or an earlier version of this same unit. (They are much better built today.) Like the original Schaller, this one has a very thick base plate. New ones still use the original molds authorized by Floyd Rose when OEM production originally began, unlike the degraded Chinese knockoffs found on AliExpress, Amazon, or eBay today.



  • Aria Pro II. Since 2009, Aria Pro II's XX-1 (Flying V) and ZZ-1 (Explorer) reissues have been fitted with the FRT-20. In Ari Pro II catalogs it is listed as "FRT-20."


  • Jackson: The FRT-20 was known by Jackson and Charvel as the Jackson "JT500." It was used from 1995 on some Jackson "Performer Series" guitars. Higher-spec Jackson and Charvel guitars built during the same period were generally built with either the original JT580 (Takeuchi TRS-101) or original JT580LP (Takeuchi TRS-PRO), or the Schaller JT590 (German Floyd Rose OEM.) The JT500 is Jackson Part# 9290650402. 



  • Kramer (by Gibson): When Gibson Guitars bought Kramer Guitars out of bankruptcy in 1997, Gibson resurrected the brand and sold Kramer guitars via U.S. online shop MusicYo from 1998 until 2009. The enduring partnership between Samick and Gibson for the production of Gibson's Epiphone brand led to Epiphone managing Samick's production of the new Gibson Kramers.The FRT-20 was supplied as an OEM product to MusicYo Kramer guitars made in the 2000s. There were some lefty models, such as the Striker FR-424S LH, and the Baretta FR-404S LH. The FRT-20 is the perfect replacement for a tired Kramer-branded FRT-20 from the MusicYo era.



  • Douglas: Rondo Music is a U.S distributor of musical instruments and accessories that has been in business since 1959. They are famous for the huge range of beginner and intermediate-level guitars that they get in from China and Korea, under different brand names, e.g. "Agile", "SX" and "Douglas." As these brands have matured so has their quality and reputation, as well as their price. The FRT-20 found its way on some early Douglas guitars including this mid-2000s left-handed Douglas Hadron 625.



  • Shine guitars are made in Korea by Saein Musical Instrument Co. Left handed guitars were available and some were fitted with the FRT-20 Floyd Rose II clone. The pictures below are possibly from a left handed Shine SIL-602AN or Shine SIL-70 model.



  • Applause GTX Series: Kaman Music Corporation's Applause brand produced the "GTX" Series of Superstrat guitars from 1988-1994. These were aimed at beginners and intermediate players with guitars made in Korea by Samick. Some were built with this tremolo. The baseplate was stamped "GTX." I am not certain of there ever being lefties.


  • ESP: "Grassroots" is one of the entry-level brands of ESP. Some guitars such as this (right-handed) Grassroots Horizon were built with FRT-20



FRT30 : Takeuchi TRS-101 replacement


The FRT-30 from the "Korean catalog" is the Takeuchi TRS-101 clone from the Korean universal OEM pool. This unit has been used by multiple guitar brands for over 20 years, and moreso when the Takeuchi original became unavailable when the company closed down in 2010. Many left-handed guitars have been manufactured with this unit. This is a testament to its quality. I have brand new stock of the FRT-30 Complete kit with L2 nut, 36mm block and all accessories to do an immediate swap. These units are better quality than the current Floyd Rose Special.


Most guitars manufactured in China with some sort of Floyd Rose tremolo do not use this unit. Chinese factories draw from the Chinese univeral OEM pool. The Chinese versions are inferior.


  • B.C Rich: From 1997-2003, some B.C. Rich "N.J Series" guitars made by World Musical Instrument Co. in Korea were built with the FRT-30. It replaced the KKT-3 double-locking tremolo made by Jin Ah. In B.C Rich catalogs it was listed as "Double Locking Floyd Rose licensed tremolo." It was used on the "N.J Neck-Thru Series" and some "N.J Platinum Series" models including left-handed models such as this Platinum Series Warlock, this N.J Warlock, and this N.J Neck-Thru Warlock. This 2005 lefty Platinum Pro Series Warlock is another example. After dabbling with the ill-fated Floyd Rose Speedloader between 2003 and 2004, it appears B.C. Rich returned to this unit in about 2006.



  • Gaskell: My original factory range of left-handed guitars and basses was manufactured from 2008 to 2012. Although my guitars were made in China, all my hardware was Korean. I used Jin Ho tuners and Sung-il hardware, and my Floyd Rose tremolos came from the same universal OEM pool as every other brand in the world at the time. I used the FRT-30 on special-ordered left-handed Explorers that I offered through the Gaskell Pro Series. It was the stock tremolo on my left handed Kelly and left handed Randy Rhoads V models. Authors comment: I have a very banged up early-2010s Gaskell Concord that I have gigged hard with over the years, and still use to this day, that has one of these, and even after all these years it stays in tune and performs 100%.




The "Chinese catalog"


No business using Chinese manufacturing ever deals with the factories themselves. China has a strict system where trading companies are the organizations that deal with buyers and source from multiple factories to produce OEM products. This is why different guitar brands use the same factories and the same hardware, whether they know it or not. The trading companies all use the same catalogs. It could be a hundred different factories in China that make the products that guitar brands source from the universal Chinese catalog.


The Chinese codes are BL + a product number, e.g. the Chinese TRS-101 clone is product number BL001. They all have "Licensed Under Floyd Rose Pats." on the block and often also on the tail.


Some of these products are not actually clones but modified variants of a well-known product; e.g., there never was a Takeuchi string-through TRS-101, but there is one in this OEM pool.

The following are examples of guitars built with Floyd Rose style tremolos from the "Chinese catalog."



  • ESP: ESP's entry-level brand "Grassroots" is made in China. Some Grassroots guitars used the BL-001. An example is this late-2000s left-handed Grassroots Original Series G-FR-62GT. (This model is discontinued.) Note: There was an Edwards version of this same guitar, model Forest E-FR-145GT, which came instead with a Ping Well Floyd Rose tremolo.


  • Rondo Music. Agile, SX, and Douglas are longstanding budget brands marketed by Rondo Music in the United States. This left handed Agile AL-2500 uses the TRS-101 clone from the "Chinese catalog."



Glossary of Terms


  • Batch-produced: Stock products manufactured in limited runs, not custom orders.

  • Custom order: Made-to-order units, often with long lead times or higher cost.

  • Double-Locking: A system where the strings are clamped at two points: the bridge (via saddle blocks) and the nut (via a locking nut). This removes the tuning pegs from the equation during play.

  • Fine Tuners: The small knurled screws on the back of the bridge used for precision tuning after the nut has been locked.

  • Knife Edges: The two sharpened points on the baseplate that pivot against the mounting studs. This is the "friction point" of the system.

  • License stamp: “Licensed Under Floyd Rose Pats.” on a tremolo post-2008 does not indicate an active agreement — it’s legacy tooling or marketing.

  • Licensed Floyd Rose: A tremolo made under official Floyd Rose branding but by a third-party manufacturer.

  • Locking Nut: A nut consisting of three metal pads tightened by hex bolts. Lefty Note: Nut sizes (R2, R3, R4) are mirrored for lefties (L2, L3, L4). A right-handed nut cannot be used on a lefty neck.

  • N.O.S. (New Old Stock): Unused parts from discontinued production runs.

  • OEM (Original Equipment Manufacturer): A third-party company that produces parts for other brands.

  • OFR: Original Floyd Rose. Applies to the modern FRT100 Series currently made in the USA and formerly made in Germany. Historically also refers to the Japanese and German FRT-5.

  • Proprietary: An in-house design, self-branded and used only for the company's own products, usually manufactured by an OEM. For example, the Jackson JT6 tremolo was a property of Jackson-Charvel in the United States, manufactured by OEM Ping Well of Taiwan.

  • Radius: The curvature of the saddles. A Floyd Rose must match the fretboard radius (e.g., 12", 16") to ensure consistent string height.

  • Tremolo: A musical effect where the volume (amplitude) of a note is rapidly modulated, producing a pulsating or shuddering sound. It is distinct from vibrato, which otherwise affects pitch, not volume. For decades, this term has been technically misused to describe pitch-bending effects such as those produced by guitar vibrato systems.​

  • Upcharge / Surcharge: An upcharge is an extra charge for an additional service or option, while a surcharge is an extra charge added to the standard cost, often for specific circumstances.

  • Vibrato: A musical effect where the pitch of a note is varied up and down, usually rapidly, creating a warbling or wavering sound. This expressive technique adds warmth and richness to music, commonly used by singers and instrumentalists.
