Many thanks for that - I had no idea. It will give me a good point to start from and to experiment. Yes, it was great being able to handle (if not play) some beautiful guitars. Macari's used to be London's pre-eminent Gibson dealer but, for whatever reason, I believe they parted company. They used to have 2 shops (one on Denmark St and the other on Charing Cross Road) but now just have the Charing Cross Road shop. It's always busy in there and the owners / staff are a really helpful and nice bunch. Always worth a quick look-see if you're in the area.
