To prolong the life of the valves it is always advisable to switch on the Mains Power Switch (item 1) about 2 minutes before switching on the Standby (item 2). On switching off, the Standby should always be switched before the Power Switch. The standby facility is particularly useful between sets and before playing, as it allows you to keep the valves operating at a functional temperature but without any sound being produced. 10. Channel A Controls the reverb level on Channel A. Ultra Gain / Channel B 11. Lead 1 / Lead 2 Switch The DSL 100 and DSL 50`s Channel B features two modes. The first, Lead 1, gives an open high gain crunch, with traditional Marshall characteristics, similar to a hotrodded JCM 800 2203 master volume. The Lead 2 mode however gives a mid-boosted tone coupled with even higher gain possibilities. 3.

As the amount of gain increases so will the distortion level in your sound. 4. Presence Control Adds higher frequencies to the guitar tone, creating crispness and bite. Turning this up will make the sound more cutting and in your face. 14. Treble Control Controls the high frequencies of the guitar tone, making your guitar sound brighter when increased. 15. Conversely reducing the amount of middle in your tone will result in a sharper and thinner guitar sound for the classic "scooped" tone. Classic Gain / Channel A 17. Bass Control Controls the amount of low frequencies or bottom end in your tone. 18. The first, Clean, is reminiscent of an early 1959 Plexi Super Lead head. Depending on Gain settings (item . 19) this mode will take you from clean to a controlled Plexi style crunch. Tone Shift The Tone Shift Switch reconfigures the tone network components to give a new dimension to passive tone shaping. With the switch selected to the "in" position and the Middle Control (item 6) turned down the result is a scooped mid sound ideal for certain classic metal styles. 19.
