I have a Martin 00018. It weighs about as much as a packet of tissues and has a wonderful tone and action. I got is second hand and had a bags pickup put in it, a refret and I would not part with it. Volume-wise my Maton M325 Knocks the pants off it. The Maton also has a lot more bottom end. I think one of the best guitars I've ever owned apart from the martin was a Kasuga that I bought in the early eighties (when they had their own factory in Japan) That was some guitar. Derek Brimstone has a limited edition Kasuga which has an eagle inlaid on the back in mother of pearl. God knows what it's worth but it's great.bugsy
