On the front panel, a 5-band EQ with +/-15dB per band sits alongside a one-knob compressor, tube-emulated overdrive, sub-harmonic generator, a Shape button for classic Ashdown voicing, and a VU meter for level monitoring. Drive and sub-harmonic effects are footswitchable via an optional FS2 footswitch.
