From the Aspen Guitars page on Facebook:
History Lesson:
Aspen was a brand name of a distributor, the International Music Corporation (IMC), of Fort Worth, Texas. This is the same company that imported Japanese guitars under the Hondo name. Aspen guitars were initially produced in Japan and later Korea (I believe). The Japan years were throughout the 70's, I do not have exact dates, but the early 80's Aspen models marked 'Made in Korea' are questionable in quality and consistency. The Japanese made models were generally quite good playing guitars. The Korean made ones are hit and miss on quality. The Japanese made acoustics were good copies of Martin models and 1 model (the DH-32) made to resemble the Gibson Dove. They also made Strat, tele and Les Paul and Gibson 335 copies that were quite good looking guitars. There are also bass guitars that are similar to the Fender P. A few weeks ago I saw a bass that resembled a rickenbacker. I personally have never touched an electric model Aspen and can't speak to the sound quality.
