JCM600 JCM Valve Combos & JCM 600 Valve Head.
ENGLISH From the Chairman I would like to thank you personally for selecting one of our JCM 600 valve amplifiers. For over thirty five years now my Company has been recognised around the world as one of the leading manufacturers of quality amplification.
ENGLISH WARNING! Please read the following list carefully. A. ALWAYS fit a good quality mains plug conforming to the latest B.S.I. standards where necessary (UK only). B. NEVER attempt to by-pass the fuses or fit ones of the incorrect value. C. NEVER attempt to replace fuses or valves with the amplifier connected to the mains. D. DO NOT attempt to remove the amplifier chassis, there are no user serviceable parts. E. ALWAYS have this equipment serviced or repaired by competent qualified personnel. F.
Vintage Overdrive Switch to the Overdrive channel which is indicated by the Red L.E.D. Again pickups will obviously influence settings but you will probably find that gain settings of around 5 or 6 are quite adequate, the key however is to increase 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.
ENGLISH 13) Treble Control correct type and rating. It is a wise precaution to always carry spares. Controls the upper or treble frequencies in the tone of the Overdrive channel. 2) Mains Input Please Note Connects the amplifier to the mains power supply. The Tone Controls are interactive and adjusting one can effect the relative amounts of the others. Experimentation is the best way of finding your own personal favourites.
Note This Master Presence control adjusts the amount of top end frequencies in the overall tone - adding crispness and bite. The JCM 600 combos and head will deliver 60 Watts into either one or two 16 Ohm speakers, ie. 16 or 8 Ohm total impedance. The unit should not be driven into a load of less than 8 Ohms. 10) Speaker Output On combo formats of the JCM 600 this jack is for connection to the internal 16 Ohm speaker.
