The Ibanez JEM505 is a JEM series electric guitar model and signature model of American guitarist Steve Vai, introduced in 2010. Like the JEM555, it is an affordable JEM model, but from a different point of view. Unlike the JEM555, the JEM505 is produced in Japan and has "Japanese made" features like a Prestige neck and A class tremolo, but it does not feature US made DiMarzio pickups like the JEM555 does.
