Mine was reasonably loud but lack the punchy bass, tone quality and volume of the GC30A. I believe removing the finish and refinish with a thinner coat will definitely improve it's sound.
I don't have a GC yet but I do have an LL steel string and the finish is so thin. I would have thought that the new GC would be just as thin. The Yamaha store in Toronto didn't have any GCs but they did have one line down and the finish on these were lovely and very fine.

Are the new GC past this finish issue?

This is how purflings look like on my GC30A.

This is the rosette design on my GC30A

The size of the marquetry blocks are probably the smallest and finest I have ever seen. Even the purflings are so fine. I have noticed many luthier avoid adding purflings to the edges of the guitar and just finished off the guitar with simple binding. I know how tough it is to do a good job with such fine purflings as I have finished several purflings on a few guitars.

They are at the top, back and back strip of the guitar.

Can anyone tell me anything about Tiawan built GC 30 with a second sound port? Are these as good as Japanese built GC 30a s?

This pattern was first used on the GC20 series from 1968 to 1973 before the GC30A was produced. The 1974 to 1977 GC30A uses this pattern and also the Yamaha's tuning machine. The 1978 to 1985 GC30A uses the Lyra shaped tuning machine (quite similar to the Gotoh Lyra tuning machine but with different engraved pattern and craved button) together with the rosette and purfling pattern used on my GC30A.

The Taiwan build GC30 was produced between 1990 to 1998. This was the period when the GC70 replaces the GC30A as the top model. It uses Indian Rosewood for its back and sides while the GC30A uses BRW. Yamaha do not use sound port on their guitars.

They are two very different guitars, however you can significantly improve the quality of its sound on the GC30 (viewtopic.php?f=11&t=101737 ).

So what does every one think of the gc22 of today. I thought some sound tracks on YouTube sounded good?

This question came to mind after I ran into a gc30a and its current price tag.

Suddenly I am wondering how good the lower priced GC stack up?

Please search YouTube under "GC30A". The video were recorded in my home with a cheapo HTC mobile phone.

I have played on the GC22, GC32, GC42 and GC82. I would say that the GC22 is comparable with any guitar in that price range. I would rate it in terms of sound to be as good, if not better than the GC41 which I used to own.
