Independent shopping perspective
The Korena take
Monumental is a black stereo tremolo pedal for guitar and bass that moves from standard all-frequency pulsing to harmonic modulation, where high and low frequencies alternate. Its S-B-H control blends those two approaches, while selectable sine, square, and ramp waveforms set the movement’s shape. In a stereo rig, the pan control progressively offsets the right-channel LFO, reaching 180 degrees at maximum for the broadest spread. Tap tempo, alternate subdivisions, and three savable presets make rhythmic changes and recalled settings accessible from the pedal.
Strong match
Who this is for
- Stereo guitar or bass rigs that need tremolo movement distributed differently across left and right channels.
- Stage set changes requiring recall of three saved tremolo settings from onboard footswitches.
- Rhythmic parts where tap tempo, triplets, or dotted-eighth subdivisions need to follow the song.
