Using similar technology to the TSL100 & TSL122, the latest additions to the JCM2000 series are the 60 Watt TSL60 head, TSL601 1x12 combo and TSL602 2x12 combo. With three channels giving every bit as much flexibility as their higher powered brethren, the TSL60s use a pair of Svetlana EL34 power valves for that classic pure Marshall valve tone.
The TSL60 series amps all have three channels: Clean, Crunch and Lead. The Clean channel has controls for Volume, Treble, Middle and Bass. The Crunch and Lead channels feature individual Volume and Gain controls, with shared Treble, Middle and Bass tone controls. The Tone Shift switch on the Crunch/Lead channels reconfigures the way the all important middle control works and the overall Deep switch adds masses of extra push at the low end.
The addition of separate Reverb controls for the Clean or Crunch/Lead channels and an overall FX Loop with Level and Mix controls, that are also on/off footswitchable means that the TSL not only gives more, but also allows the player to use the facilities in a live situation to an extent only dreamed of before. The TSL60s also feature a built-in speaker emulated DI circuit for recording or direct to the PA situations. The supplied 5 way footswitch provides remote switching for the three individual channels, plus the effects loop and the reverb.
Marshall's Research and Development team worked very closely with Celestion to develop a speaker capable of handling the power of the TSL coupled with that all important factor - tone. The TSL601 is fitted with a single 16 Ohm 80 Watt 12 inch and the TSL602 is fitted with a pair of 8 Ohm 80 Watt 12 inch speakers.
