Description

HI GAIN DUAL REVERB

The Dual Reverb range was designed for versatility with two independently controlled footswitchable

channels, each voiced totally differently.

Channel A is voiced for brilliant clean tones with the gain control (item 2) on lower settings and

crunch to lower gain lead as you turn it up.

Channel B is boosted with enough gain (item 3), for fearsome lead tones, ranging from classic on

lower settings to contemporary screaming solos on maximum.

Channel master volumes (items 9 & 11) and individual channel reverb controls (items 8 & 10) give

you incredible control and all round versatility in either, head or combo form.

VALVE OUTPUT POWER

The JCM 900 range use high quality 5881 output valves (x2 in 50 Watt models, x4 in 100 Watt

models) for their unique distortion properties and fluid tone.

With most valve amplifiers, particularly Marshalls’, the best sounds are achieved when the Master

Volumes are set high enough to be utilising the driving power of the output valves to the full.

This delicate working balance between the pre-amp and power amp levels can only be achieved by

experimentation.

You will find that all the JCM 900 models like to work hard and are designed to withstand prolonged

use at full power quite readily. The PB100 Power attenuator is ideal for this use (connects between

amp and cabinets) as it will allow you to run your amp at full power but keep the overall volume low.

The important thing to remember here is that it is the interaction between all the controls that plays

a part in achieving your sound.
