Marshall product info:

Expression begins with the all valve OriginTM series. It delivers two inbuilt voices, a new tilt control, PowerstemTM our new power reduction technology and forms the perfect marriage with FX pedals.

There is a 2-way footswitch available with all models so you can control the gain boost and turn the FX loop on and off. The series has something for those playing in the bedroom, at rehearsal or on the stage.

Key Features
A little extra boost
Crank up the gain by using the pull boost feature. You can add a little extra grit and distortion to your sound.
You have the power
Our new power reducing technology, Powerstem allows you to have high or low power modes without compromising on sound quality.  
What is Powerstem?
Powerstem works by reducing the voltage rails around the power amplifier rather than using our traditional pentode/triode reduction methods. This offers power reduction without changing the sonic character and so provides optimum tone and performance regardless of the volume level required by guitarists.
Tilt and control
Using the tilt control you can change your blend your sound from normal to high treble. This is based on the multi-input technology of our more classic amps such as 1959SLP and JTM-45 but in a single controlled knob.

    10" Celestion V-type speaker provides classic British tone
    Separate Gain and Master controls for dialing in the right amount of crunch
