Can I 'twist' this thread slightly and ask for advice on 12 string models - size, manufacturer and whether all mahogany. The problem is I will probably have to buy 'blind' on a quick trip thru the US (I'm based in the UK)so probably won't get the luxury of trying out various options. I've done some groundwork and have narrowed down to these half dozen 'possibles': MArtin J12-15, J12-16GT,D12-1, DM12 Gibson J-185 (pricey?) and Guild JF30-12 Maybe I have missed some? I presently play a Yamaha FG412 and want to upgrade. I sing/play in an acoustic group, mostly pubs, some clubs and with NO amplification (!) so volume does count! Any suggestions/guidance?
