Reverb self-oscillation
Extreme parameter settings can cause the reverb effects to self-oscillate or cause other
unexpected sounds. This behavior is identical to the original 224 hardware and is caused by its
internal 12-bit architecture.
Internal algorithm overloading can be especially apparent with very long reverb decay times. To
reduce any artifacts, simply lower the reverb decay times with the Mid, Bass, and/or Treble
knobs, and/or reduce the input signal level.
Notes
The Mid, Bass, and Treble knobs control the reverb decay times for the middle, bass, and
treble frequency bands. The Bass and Treble knobs are not reverb filters or EQ controls.
Bypassing the pedal does not stop self-oscillation. In True Bypass mode, self-oscillation
continues while the pedal is bypassed and returns when the effect is re-enabled. In Trails
Bypass mode, self-oscillation continues when the pedal is bypassed. Reduce the Decay
levels to stop self-oscillation.
Footswitch
The footswitch toggles the effect on/off. The LED lights to indicate when the effect is active.
The LED color changes to indicate the pedal settings for True and Trails bypass and Predelay.
