[. . . ] TSL100 & TSL122 TRIPLE SUPER LEAD Valve Amplifiers JCM 2000 ENGLISH From Jim Marshall I would like to personally thank you for selecting one of our JCM 2000 Triple Super Lead valve amplifiers. Since I started Marshall Amplification in 1962 I have witnessed some incredible breakthroughs and advances in amplifier design technology, such as master volume amps, switchable channels, reverb, MIDI technology, speaker emulation and digital effects processing, to name just a few. These may seem like every day features nowadays but this certainly wasn't always the case. However, the same values that were present in the first Marshalls are still here today. [. . . ] For more information see FX Loop section 8. Presence Control and Deep Switch The presence control will boost the upper mid / lower treble part of the tone giving it more up-front brilliance, great for cutting through overactive cymbals. It is suggested that initially you set the controls midway and experiment from there, rather than the `everything on 10' method favoured for the earlier non-master Marshall amps. Remember, increasing the treble is going to make the distortion more `fizzy' and `cutting', whereas increasing the mid will make the distortion more fluent and sustaining but probably not as dynamic (in the modern sense). Try what you will, there are many textures to discover. FUNCTIONS 2. Gain Control Again this controls the input sensitivity of the channel but with the effect of being capable of much more gain and hence more dramatic distortion. At low settings, the channel is relatively clean (although darker in tone than the clean channel) and makes a good alternative for gentler, bluesy style solos. With a bit more gain the tone becomes more aggressively traditional Marshall rock with the emphasis on chunky power chords. Take the gain control to the limit and we enter modern high gain crunch territory, with probably more gain and dynamics than other manufacturers would put on their lead channels! 6. Master Section Controls As with the Clean channel the Reverb, FX mix, Presence, and Deep functions can be adjusted independently of the Clean channel but remember these controls are also used in conjunction with the Lead channel. 3. Volume Control Again this controls the balance and level of the crunch channel against the rest of the TSL. 3 LEAD CHANNEL 1. Mode Select (please refer to diagram C, Page 28) Output Mute By the nature of the `V. P. R. ' circuit, we can now turn off the signal to the output valves. As the speaker emulating DI output is connected to the same place, this enables the TSL to be DI'd for silent recording, yet maintain the compression and harmonics of a push-pull valve stage. ENGLISH To access the Lead channel - both front panel `mode select' pushswitches must be pushed in (with or without the foot controller connected). If using the foot controller press the Lead switch. The Lead LED (red) on the front panel and on the foot controller will now be illuminated. Power and Standby Switches FUNCTIONS As you can see the control line up in the `Lead' mode is identical to the `Crunch' mode, except now you are using the other row of controls. Operation of the `Lead' channel is exactly the same as the `Crunch' channel, but with a lot more gain and compression to play with. This channel will still clean up with low gain settings or from the guitar's volume control. BUT, when wound up the dynamics and response of this channel will follow your every move. When speed picking the amp will follow every note without blurring and when playing slow legato runs, the amazing sustain will bloom into controlled feedback hanging on for as long as you want. Experimenting with the Gain, Volume and EQ controls will yield an extremely wide palette of tonal textures. These are a very important part of your valve amplifier and to help maximise the life of your output valves. Please remember these simple but important rules : 1.
