Think of this as your rig’s new “tremolo channel”. They’ve adapted the deliciously sloshy, transistor-based LFO and distinctive waveform from favorite “West German” device, modified its speed and depth to match and go beyond those from your favorite classic amps, and then added pre and post effect gain stages for both overdrive and volume boost. Then they offer the classic, dramatic amplitude modulation (AM) you might expect, or a filtered modulation (FM) that is subtle, beautiful, and less invasive on your playing.
