I like your guitar designs, and I like site design too. It's a good idea, just feels like it needs some refinements to make it better.
The main source image you use for your site looks 'fuzzy'. Maybe it's just the stark contrast between the black and the guitar, but I think it could do with being a higher res photo, or sharper somehow. Do you have photoshop to play with?
The inlay gallery scrolls a bit too quickly, either give the user ability to move through designs themselves, or give at least 3-4 seconds after the fade in of the complete image to view before changing.
As for the guitar gallery - take photos on white or black backgrounds, with decent amounts of light. People (and possible customers) will not look as favourably on a guitar that's leaning against a windowsill or on a pillow as they will a guitar in a semi-professional setting.
The main photo on the front page is also too long - I'm on 1024X768 and I have to scroll vertically. It feels like your site doesn't want to use pages of scrolled information (hence the current layout), so maybe you should consider shrinking it vertically to fit the world's most common screen res (at present that's the same as mine).
Also, your articles are word documents. Bad idea. Use PDFs. If you want them converted to PDFs, I can do that for you, chuck me a PM.
I know I've put a few points down, but my view of the site is not a negative one, it shows promise, I just want to give my views to help you make it better, hope you take it in the spirit it's meant
