I tried out the 500X on a Line 6 amp and a Crate amp. Sounded great so I bought the 500x But brought it home to my Bugera 1990 tube amp with Eminance 2X12 cab and the 500X sounds really THIN and QUIET!!! (yes the Bugera 1990 is the Marshall JVM {or is it jcm?} knockoff but 1/6th the cost, but good heavy sound just like it) I hooked the 500x up just like my analog pedals, but the sound is dinky, figured there's something i need to know to get this going right?
