Personal checks are fine. Out of state checks clear in a day or two now. Money orders, no problem. Wire transfers work well. We recommend wise.com for international wire transfer. Sorry, no credit cards. (I don't have to charge you the extra 3%) I have a liberal layaway plan to help people buy expensive guitars. Email for details.
USPS & UPS mainly. In 45 years I've had one UPS claim and they paid it. I don't like Fed Ex but I'll use them if you want. Don't expect them to pay a claim on a vintage guitar. Proper packing prevents problems. I take care to pack so gear will arrive safely.
I don't buy anything I wouldn't want for myself. It's very rare I'll buy something that's not 100% original, but if it has changed tuner buttons or been refretted, I'll tell you. Detailed, accurate descriptions only. Please call for an in hand description. I go to a lot of trouble to pack this stuff right for shipping so it will arrive undamaged. I sell only really nice amps, fully serviced. No returns.
