The Trem-Spring contains two independent effects, which can be used separately or together:
Spring style reverb + Tremolo like effects on board an amp.
w/ the FX ORDER toggleswitch it is possible to invert the series of effects:
lever up: first the Tremolo into the Reverb (The tremolo effect ends in the "tail" of the reverb and is somewhat compressed)
lever down: first the Reverb that goes into the tremolo (The "tail" of the Reverb ends in the tremolo generating a DELAY type effect that can be managed by the speed knob of the tremolo. the effect is more open and not compressed at all)
Tremolo Section:
SPEED: Controls the speed of the tremolo beat
DEPTH: controls the depth / amount of the effect
LEVEL: General volume of the effect, FLAT position at 12 o'clock. turn it clockwise when you are using higher speeds.
tempo red led.
Reverb section:
DECAY: controls the decay / length of the reverb
MIX: Controls the amount of the effect by mixing the "clean" sound with the Reverb
