I bought this tool for my new-to-me JEM 7DBK, having previous experience with the same tool being included with my Prestige RG.
If you own an Ibanez, this tool is invaluable - it fits right in your case or gig bag, and has everything you need to completely work on your guitar or bass, no matter the bridge it's equipped with. The multitool has great build quality - very nice wrenches, the ruler is easy to read, and nothing is stiff or loose. Just very very nice quality in general.
