Have been playing with a new 89F since Christmas and used it for first rehearsal yesterday. Goes into an H&K Grandmeister head and cab. No issues so far and I like it very much, especially the neck. Band members thought it was a better sound than my previous guitar which goes to show a $4K PRS doesn't necessarily make the sound you want for a live band - we play fairly standard rock and pop covers. I bought it for gigging not recording and so far the ability to switch tunings and use different sounds including acoustics has made a big difference to several of the songs and saved messing about mid-gig with capos and re-tuning. I added a Tremolo-No and set it to dive only to prevent strings going out of tune if 1 should break during a gig - took about 30 mins to do.
Generally I find posts on forums are from the hopefully relatively few people who are having problems rather than the many who are more than happy - which can give a negative impression of any product. So far I find it is a great guitar, actually better than I expected, even just on the mag pups which sound almost identical to the Lester models. Will probably post a more extensive review after a few more weeks and a couple of gigs.
