The RGX 600 range page 3

The remaining 612 range


In error I have omitted the 612J from the early models so I am including it here even though it was launched in 1987. The other two models are the 612 JS and 612V launched 1990 and 1991 respectively. All models are Made in Japan


612JS in Crimson Red

I have been unable to find any pictures of the 612V so if anyone has any I would appreciate you letting me have them

Comparison of the J and JS Headstocks I don't have a picture of the V I do now see headstock picture immediately above and August 2020 update below


Update May 2020
Nathan Mafan has sent me pictures of the 612JS he owned which had the free art pickguard this model doesn't appear in any catalogues so it's difficult to know if this was a standard offering, a one off order or an aftermarket modification but it looks original here it is




Update August 2020
Sergei Bondarenko from Russia has very kindly sent me pictures of his 612V see headstock above and further details below. Thank you Sergei
