Yes, Yes, Yes!!!
As a full time working musician, and a part time guitar/voice instructor, I fully endorse the quality and value of JamPlay. As Per says, give it a try, for free. If you like 'em ,buy 'em , if you don't, don't. It's as simple as that. The least we can do is give 'em a chance, right? The lessons are personal and help in areas where help is needed.
As Per mentioned, the money these fine folks at Jam Play spend here on Chordie are partially essential in keeping this wonderful site up and running. There are lots of folks looking for instruction for virgin guitar players. In my humble opinion, it would serve all of those who care about the continued existance of Chordie to recommend JamPlay instead of the justin whats' him name, in the future. Ya'll dig? Many people have asked how they can help to keep Chordie alive. This is a pretty good sign and an absolute solid source to answer the survival question. Those who can play, keep on keepin' on, ( until you get stuck, then call upon JamPlay) those who know others that wish to learn, refer them to JamPlay.
Mmmmmmmkay? Mmmmmmmkay.
