What's the diff with the OM-28JM and the OMJM? Also, you can get the regular production OM28V which is essentially the same guitar (better bracing in my opinion) than the OMJM for probably a few $$ less.
i can't get use to the V neck. the JM signature has a slim neck which worked perfect for me.
but yea, i tried the OMJM and it was an excellent piece of instrument. the sound was sweet and action played like butter.
hence i am now looking for a OM-28JM
Amazing guitar! I am satisfied with both of my OMJM and OM28JM. You really can't go wrong with the OMJM--price wise...It will be really hard to find a used OM28JM for under $4000. I should mention to you that there is one used at Ebay for $4800(model#118). If you have the$$$$ go for it!--they will continue to go up in price because of the limited run and simply because it's JM's main acoustic gear. Good luck!
