I will try to find out later. I have a guitar magazine from 94 where J is featured. I´ll check there. Not sure though about what acoustic guitar they talk about there. The interview is from london where he is shopping records, Deep Purple and Cinderella, and playing an acoustic gig. Hmm….Now I suddenly remember what guitar they talked about. It was a Martin NewYorker. Not sure if he even had the Gibson acoustic guitar at that time…
