I recorded clips of my guitars with the same amp settings and came up with the conclusion that my 7620 has considerably less sustain than my Les Paul or a pair of Schecterii. Granted, everything else has a fixed bridge, but I really have to pump the gain to get long ringing chords out of the thing.
Is this normal?
Are there any major points I should investigate to improve sustain? Neck-to-body tightness? Add large sustain block?
