SIGNAL FLOW (from right to left): Input > Sustain > Blend > Transformer Output

AUDIO CONTROLS

1. INPUT: Input level; +9dB to +30dB; More gain creates more compression
2. SUSTAIN (compression): Determines amount of compression (gain-reduction); Higher levels provide
more compression (lower threshold)
3. BLEND: Mixes the dry (uncompressed) signal with the wet (compressed) signal.
4. OUTPUT: -inf. to 0dB output level control; 0db (no cut) is fully clockwise

SWITCHES

A. ATTACK: Sets the compressor's attack time to either FAST (1ms) or SLOW (10ms)
B. RELEASE: Sets the compressor's release time to either FAST (300ms) or SLOW (1s)
C. TYPE: Selects between feedback (OLD) or feedforward (NEW) compression styles
D. BYPASS: Buffered bypass footswitch
