9) Presence Control

This Master Presence control adjusts the amount of top end frequencies in the overall tone - adding crispness and bite.

10) Speaker Output

On combo formats of the JCM 600 this jack is for connection to the internal 16 Ohm speaker. On the JCM 600 Head this socket is for connection to an external speaker cabinet, such as the purpose built JCM C410A compact 4x10” angled cabinet and/or the JCM C410B compact 4x10” base cabinet.

11) Speaker Output

For connection to an external 16 Ohm speaker (The Marshall JCM C12 1x12” and JCM C212 2x12” cabinet are designed for use with JCM 600 combos).

On the JCM 600 head this output could drive a second JCM C410A or JCM C410B cabinet.

Note

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.

If you unplug the internal loudspeaker in a JCM 600 combo it is possible to connect a single 8 Ohm cabinet to the extension Speaker Output only. However, when the internal speaker is connected only a 16 Ohm extension cabinet may be used.

It is important to follow these instructions as failure to do so may lead to the amp running into the wrong impedance, which will ultimately cause damage.

JCM600 specifications

Marshall Amplification is renowned in the world of music for producing iconic amplifiers that have shaped the sound of rock and roll for decades. One of their standout models is the JCM600, which combines modern technology with classic Marshall tones.

The JCM600 is a versatile tube amplifier designed for guitarists seeking a powerful performance with a variety of tonal options. This amp utilizes Marshall's renowned EL34 power tubes, delivering that signature warm, rich sound that the brand is famous for. With its robust construction and thoughtful engineering, the JCM600 can handle the demands of both studio and live performances.

One of the key features of the JCM600 is its dual-channel design. This allows musicians to switch between clean and overdriven sounds seamlessly. The clean channel maintains clarity and definition, making it ideal for chords and intricate playing. In contrast, the overdrive channel offers a rich, saturated tone that can be adjusted for everything from classic rock rhythms to higher gain sounds that suit heavier genres.

The amplifier includes a range of tonal shaping options. The presence and resonance controls allow players to fine-tune the high and low frequencies, respectively. Additionally, the JCM600 is designed with a three-band EQ—bass, middle, and treble—enabling musicians to sculpt their tone to perfection. This level of control makes it a favorite among guitarists who are particular about their sound.

The JCM600 also integrates modern technology with features such as a built-in digital reverb, adding depth to the overall tone. This reverb can be adjusted to suit the player's preference, whether they desire a subtle ambiance or a more pronounced effect.

Moreover, the amplifier is built with durability in mind, featuring a rugged chassis and high-quality components meant to endure the rigors of touring musicians. The cooling system is engineered to prevent overheating, ensuring reliable performance in even the most demanding environments.

In essence, the Marshall JCM600 encapsulates what guitarists have come to expect from the brand: powerful performance, incredible tonal versatility, and robust durability. Whether on stage or in the studio, this amplifier ensures that musicians can express their creativity and achieve their desired sound with ease.
