HI GAIN MASTER VOLUME SL-X The latest innovation from our valve designers involves the use of an extra ECC83 pre-amp valve in the gain stage of the Master Volume SL-X models. This gives a gain soaked front end that is the most extreme yet produced by Marshall and is controlled by twin gain controls, the first (item 2), from 0-10, the second (item 3), from 10-20! Combinations of these two controls can take you from classic Marshall crunch in lower positions, to pure overdriven outrage on maximum. - Page 5 NOTE: Combinations of the two gain controls (items 2 and 3) provide a wide range of clean, crunch and overdrive possibilities. Experimentation will reveal the optimum settings for each. 4 & 5. Master Volume “A” Master Volume “B” Twin footswitchable Master Volume Controls. Master “B” controls the overall volume exclusively when a footswitch is not connected.
