SL-X and Dual Reverb are two entirely different animals. The pre section of the SL-X is completely different from the Dual Reverb, and the controls are also completely different. The SL-X has plenty of gain, to be sure. The Dual Reverb, in stock form, has about enough usable gain for a pretty decent hard rock tone and anything beyond that becomes thin, clunky, and unusable.
