Re: Need an advice on 8 string.
I'm guessing you already have seen this, but have you looked at the semi-custom Agile order page? I'm not sure if all of those have the double truss rod system, but you can at least choose a scale length which is more suitable for you. Although it'll be a long wait!
My Septor is 27" and I have small hands - isn't a problem for me http://www.rondomusic.com/customquote.html
I don't really see any other options for that kind of money, besides finding something used on eBay. No doubt there are some Asian companies who will offer something, but I've no experience with that.
Yeah, I've seen that page. But on the top of the page, what does "orders for September production are closed" mean? Maybe I would ask Rondo if they can make a version with a single truss rod with two carbon fiber supports like Schecter.
I've been looking if there are good Chinese custom guitars with reasonable price. So far no luck. Korean custom builder normally asks for more than 1 or 2G USD these days. No hope for Japanese builders due to the really high Yen at this moment.
Among the 8 string builder database here, Halo Guitars seems to be offering the most reasonable prices. Are day made in the US? By looking at the prices, the prices looks almost impossible for US made guitars.
