Bill, I have a 70's single cutaway thick acoustic (dreadaught style) Guild that I bought from a store owned by my best friend. A local musician ordered it; then couldn't pay for it. It is sunburst, with a sharp cut-a-way. It has an added Martin piezo inside and a jack where the pin-strap is...no visible alterations. You need to use an outboard pre-amp, and that's a little inconvenient.
Been out of the case twice. Been played on one commercial in the early 80's. Still has the original strings on it.
I'm partial to Guild, but have my favorite acoustics (Parker, Selmer-MaCafee (SAGA) and others). The Guild in the posted video is an X-150-single pick-up (humbucker)-two controls (traditional volume and tone). Actually, prefer nylon Bossa Ginanni acoustics over all others.
Paid cost in 1975-about $800.00, I think. I'd trade it for something, or let you take a year or so to pay for it. Three years ago, when there was a thread here about Guilds, an expert from overseas put the value in good condition at about $1350.00. you could have it for my original cost, and I'd ship it to you for trial, with no deposit or other commitment.
Let me know, and I'll email a photo to you. It really needs to be played by a real acoustic player. That's something I never learned how to do. I'm an electric/nylon string guy. Notice, on the little piece I posted, there was no pick, and all the controls were (and always are) wide open.
