Hi there... Luna guitars tend not to be very good-sounding instruments anyway; they tend to be prettier than they are toneful, except for when they are plugged in and EQed very heavily, IMHO.

You should seriously look at FirstAct 3/4 guitars; I bought one for a student of mine because it was of decent build quality and had good enough tone that I would definitely grab it if I had to find a spare in a hurry. I'm funny that way, anyhow... I can't play well on instruments that sound bad.

Otherwise, check out Rondo Music for some decent-quality 3/4 guitars. They used to be a brick-and-mortar store in New Jersey, USA; now they're strictly mail-order, but their prices are super and for not-too-shabby gear.

Best of luck in your search!

Regards,

FG
