6. SPEED PEDAL - This is the TRS expression pedal input for controlling the
rate of the LFO. When an expression pedal is plugged into this jack,
the onboard speed knob is bypassed.
Footswitches:
7. ENGAGE – This footswitch turns the entire EP2 on and off. When the
engage light is turned off, the EP2 is true bypassed.
8. EF / LFO – This footswitch selects between Envelope (EF) and Rotary
(LFO) modulation of the phaser. Both lights are activated when you
are in BLEND mode, indicating that both modulation sources are
active.
Knobs:
9. SENSITIVITY – This dial determines the amount of signal it takes to open
the envelope. It should be used to determine how much the
envelope opens in response to picking dynamics. This control has a
wide range of adjustment to accommodate signal levels ranging
from wimpy single coil pickups up through active basses and line level
recording equipment.
10. DEPTH / BLEND – This controls the amount of LFO modulation. When
the BLEND mode is activated, the DEPTH controls acts as a mix knob
between the EF and LFO modulation sources. Turning the BLEND
control clockwise will enable more LFO modulation and turning the
BLEND control counter clockwise will enable more EF modulation.
11. CENTER – This control determines where in the audio spectrum the LFO
is sweeping. When the DEPTH control is up all the way, the CENTER
control has no effect on the sound, because the LFO is sweeping the
entire audio range of the EP2. With the Depth control at 12:00, the
center control will make the tone brighter when turned clockwise and
darker when turned counter clockwise.
12. SPEED – This dial controls the rate of the LFO
13. RESONANCE – This dial controls the amount of feedback in the circuit,
accentuating the harmonics and vocal qualities of the EP2.
Toggle Switches:
14. STACCATO – This switch turns on the intelligent mode of the envelope
follower. This circuit watches the input signal and quickly closes the
envelope when there is a pause between notes. Staccato is
extremely helpful for making the envelope POP on every note with a
slap bass or when using a high speed picking technique. Use this
function in conjunction with the SENSITIVITY control to achieve the
ultimate envelope response for your instrument.
