So, I had an 89 (this thread refers only to Korean models) and liked it, but a few things really bothered me to the point of selling it. The first was lots of clicking and popping while finger picking. I rarely use a pick and play aggressively at times. I don't have particularly light right hand most of the time. (and I'm not really ok with changing how I play) The second thing was the 89 neck profile never felt comfortable to me. That's just preference thing and I understand there are 59's and 69's that could solve that easily.
When ever I read this board and people are having problems they seem to occur most often with 89's and 59's. Pre 89F I would attribute this to the wrap around bridge/peizo configuration. I don't know enough about the 89F or the type of player that would prefer it to make a judgement but I still see less complaints about the 69. Is it just me imagining it or are 69 owners generally experiencing less artifacts and more satisfying performances from their instruments? It does have a different bridge so maybe that accounts for some of it. This is just speculation but I'm curious because I'm considering getting a 69 as I enjoyed a lot of what variax had to offer.
