Martin has a plastic guitar? I have a friend with a few old late 50's - early 60's Maccaferri plastic guitars that were very inexpensive when first made by this classic wooden archtop jazz guitar maker. They still play quite well...and I wonder if that could be said about any inexpensive wooden guitar after over 40 years in an attic. They don't sound like his famous wooden models but they were intended for a beginner market.
A beginner could start playing on one now with just as much success as the day it was built (Great low action and decent intonation). Nothing like plastic for permanance at a low price.
