The thing that got me hooked on Yamaha Grand Concert guitars is the iconic headstock. I prefer spruce. So because of this I have not considered owning the GC82S.
I am not sure I understand your point. You prefer the headstock on the GC70 to the headstock on the GC71 and GC82S, as these are more the traditional Torres style? Thus your only present choice in spruce is a GC70?

Right...got it! You should notice better bass depth and sustain with the GC70. That was one of Toshio Kato's expressed design goals when he developed the GC70.

I agree. However the 30A is more balance and have very clear treble. It does not have an over powering bass like my S.Yairi 950. I am looking into owning a GC70 next year after shifting home. I am just looking at the options now.

Hello!
I need some help with this Yamaha guitar, model GC40.
Can anyone tell me the specifications and possibly estimate the price?

Also, Andres777 could you send me the yamaha catalog via private message or just write out the specifications for this model?

Thank you for the time, energy and patience.

Esteemed HNLim, thank you for the initial information.

Jacaranda is brasilian rosewood? Also, is the bracing inside Torres- style? And is the luthier who made it someone of a good reputation?
And since I'm interested in buying the guitar, what would be the price?

Thank you for the time, energy and patience.

I think Jacaranda is a catch-all for non-Indian rosewoods. My "Jacaranda" GC50 was Honduran RW.

Yamaha uses the term Jacaranda to refer to Brazilian Rosewood. From a post by a Brazilian from the acousticguitarforum:

"Beeing a Brazilian and living in Brazil, maybe I can add some info.

Jacaranda (in here it is writen Jacarandá) is indeed a very common denomination of the tonewoods here in Brazil, even among the most respected builders.
BUT, it is usualy followed by the kind of jacarandá it is.
As an exemple, Dalbergia Nigra (Brazilian Rosewood) is Jacarandá da Bahia (Bahia is a Brazilian state). Indian Rosewood is Jarandá Indiano, Machaerium villosum (Santos Rosewood) is Jacarandá Paulista (because it is found in São Paulo state) and so on...


So, even not Jacaranda beeing a scientific name, it is the most common designation of the rosewoods used in Brazil. So this is probably why all the confusion spreaded.
We have lots os trouble translating the international wood names to portuguese, because the resulting name, if strictly translated, is already known as another kind of local wood. For exemple, Rosewood would end like "Pau Rosa", wich is a completely diferent wood (Aniba rosaeodora Ducke). Red Cedar would end up like Cedro Vermelho, but we have a wood called Cdro Rosa (Pink Cedar), wich is not even realted to the North american wood..."

Depending on the condition I should put it at between USD 1,200 & USD1,500.

So if someone wants 2000euros for it and had it repaired (the bridge was raised as the guitar was stored in a dry space I am told, but I don't get the explanation) I shouldn't even consider it unless the price is about 1200euros?

May I ask what is your estimate based on (do you have experience with the sale of such models) ?
I ask because the person is actually telling me that he is being kind in selling the guitar for that price (that he can sell it for more, 2200euros).

Honestly, I will never understand people who try to get more than their guitar is worth. I always feel like I'm being deceived by hoping to obtain a new instrument. : (

Right or wrong, here's a very rough way I figure the value of 10+ year or older used guitars in fully working condition.

In descending value:
Famous luthier ($5000 up depending on condition, maker and materials)
Popular luthier ($2500 - $4500, same as above)
Small Workshop, little known luthier ($300 - $2500, same as above) more for rare or desirable like Ramirez 1a etc
Factory ($50 - $1500, same as above)

Within these ranges in descending value:
Solid BRW back and sides
Solid exotic
Solid other RW
Solid Mahogany
Lam BRW
Lam exotic
Lam other RW
Lam Mahogany
Lam instead of solid top

Add for ebony fingerboard, fan frets, elevated fingerboard, double top, multistring etc. Double plate vs lam would also add but unfortunately not a lot do to US biases against non-solid woods.

For example a Yamaha GC signed would be a high end small workshop guitar, figure out place in the line-up, materials, condition etc. Eg Yamaha top of line guitars with solid brw and in very good condition may bring $2000+. A middle of the line GC would probably bring $1000 or less.

Thank you for the advice on estimating the price. It seems like a good starting point.
The guitar in question is Taiwan made, but is signed and is stated to be made of brasilian rosewood. It is, I guess, upper line model. Playability is something which I will find out/test later in the week (I hope).
