who knows any thing about them cause i got one and it great ...so could you guys tell me about them ...thanks
They were invented by the leader of the band Boston, Tom Scholz, he produced them for a while but then sold the company to Dunlop, who now just produced the Ace series of headphone amps. Personally I love my Rockman gear and the tone is amazing!

If you really like the DG, you should look into getting a Sustainor, it's more customizable and sounds awsome too!

Happy playing!
