FX - Rock Stack

 

 

This FX unit is modeled after the seminal and iconic '64 Marshall JTM45™ amplifier. Originally based on the Fender Bassman™, it used 12AX7 tubes for more distortion and had an aluminum chassis, to reduce hum. It would be easier to list who has NOT used this amp, than who has!

Complete with a full set of amplifier controls, it comes with selectable, high-end mic and preamp combinations. Controls for the head and the cabinet which can be used separately or in combination with other amps. Mix and match heads and cabinets!

 

• PAGE ONE CONTROLS

BASS

Bipolar control which cuts or boosts low frequencies. 

MID

Bipolar control which cuts or boosts mid-range frequencies.

TREBLE

Bipolar control which cuts or boosts high frequencies.

PRESENCE

Sometimes referred to as Brilliance or Edge, Presence boosts very high frequencies and slightly rolls off the low end.

LEVEL

The Level knob controls how much signal is sent though the "tubes" in the first gain stage. Higher settings can introduce a pleasing distortion.

MASTER

Master volume.

 

• PAGE TWO CONTROLS

GAIN

The Gain switch introduces a gain boost into the guitar amp, like a “High Gain” switch. 

BOOST

This is a tone control that when increased simultaneously boosts the high frequencies and attenuates the low end.

AMPLIFIER

Enables or disables the amplifier model.  If the switch is off, then none of the amplifier controls will be active. The only active control will be the Speaker Mic and you can use the cabinet with other amp heads.

CABINET MIC

Drop-down menu for selecting an impulse response of the speaker cabinet using a variety of preamps and mics.
