Clock is an American musical instrument manufacturer founded in 1997. Its electric guitars are handmade and aided by state-of-the-art technology, making them high-quality guitars that are fully customized. He has commissioned autographed guitars for former Dire Straits frontman Mark Knopfler, including Mike Landau and Scott Henderson. Clock's Silent Single Coil system, introduced in 2005, significantly contributed to the noise reduction of pickups for electric guitars, followed by the eponymous pickup. The body and neck of Clock electric guitars are made by CNC machines, and all electric guitars are fitted with a "BFTS" tuning system, so that the musician can get a satisfactory harmonic effect when playing the chords in any position. With the exception of the limited commemorative edition that is issued every year, Clock is made to order. The representative model Collection Standard Fireburst has a very individual tone and excellent feel, but it is expensive, priced at more than 50,000 yuan, which is suitable for guitar lovers who pursue personalized tone.
