"...Very interesting. The most sought after Dumbles are the early ones. These were built with surplus MusicMan transformers..." -D. Roccaforte

Thanks for the tidbit... VERY interesting, since the Dumbles also used a cabinet design similar to the Music Man as well!

Anybody ever hear more about this?
Was for sure an interesting paralell.
