As with the first version of this amp, five different voices are available. However, a Variation switch has been added, giving you one tonal variation on each voicing. This means you now have ten distinct tones, where before you had five. Also, you can now select among five different onboard effects, with three variations each. Modulation, Booster, FX, Delay, and Reverb knobs help you make your pedalboard a thing of the past.
Turn your attention to the rear of the amplifier and you'll notice quite a few connective possibilities, such as a headphones/recording output that provides the ability to direct your sound to headphones and recording devices with a minimal amount of maneuvering. Additionally, a line-out jack allows you to route line-level signal to mixers and PAs. This output can be turned into a stereo output, so you can link two 100W Katana amplifiers together for full stereo operation, with stereo effects.
An effects loop affords you the opportunity to use outboard gear and an auxiliary input jack lets you play audio from compatible players through the amplifier. If you happen to love your particular stompbox amp modeler, you can use this combo amp for its cabinet, plugging your rig into the new Power Cabinet input. This connection point lets you employ the cabinet as a delivery system for your multi-effects rig and amp-modeler stompbox.
For external control, there are two different footswitch inputs, one for channel selection/expression pedals, and one specifically tailored to the all-encompassing GA-FC foot controller.
