6. ase the master volume level As our vintage amps didn t really have a lot of pre amp gain guitarists used to crank the volume up to be heard which resulted in the natural classic Marshall overdrive roar Alternatively the Clean Channel with its volume on maximum gives a very satisfying vintage type overdrive As far as tone settings go we would suggest that you start with the tone controls set at about 5 and then adjust to taste from there The selection of tone settings for single coil or humbucking pickups will follow the same general pattern as for the clean sound Modern Hi Gain Switch to the Overdrive channel indicated by the Red L E D Turn the gain up to full and set the volume for the desired level Tone controls are set to taste though probably with the Middle control lower than the Bass and Treble controls particularly to maintain the definition when using humbucking pickups The best advice we could really offer is to simply experiment and above all enjoy the pure valve tone of your Marshall J 600 amplifier JCM 601 602 amp JCM600 Head 1 Footswitch J ack Jack socket for connection of P801 Footpedal for channel switching 2 Push Channel Switch Push switch for panel switching of the channel The push switch is inoperative when the footswitch is connected 3 Input J ack Jack socket for the input of the guitar 4 Volume Control Controls the Volume of the Clean channel 5 Bass Control Control
