Aguilar Grape Phaser (Bass Analog Phaser)
Aguilar · pedal
The Aguilar Grape Phaser gives bass players lush, analog phase shifting through a deliberately simple two-knob layout, a Rate control setting the speed of the modulation and a Color knob feeding a portion of the phase-shifted signal back into the circuit to intensify and reshape the effect into funkier, more resonant territory. Designed specifically for bass frequencies rather than adapted from a guitar-voiced phaser circuit, it avoids the thin, occasionally unstable low-end response some guitar-oriented phasers exhibit when used with bass, keeping the fundamental low frequencies solid even as the phase modulation sweeps through the upper harmonics.
What stands out
“The standout strength is genuinely stable low-end response through the phase sweep, a real functional advantage over generic guitar phasers repurposed for bass”

Trade-offs
“In a chain a phaser like this typically sits after any drive or compression, since phase modulation on an already-distorted signal can produce a muddier,”
— from the community notes
“though players wanting extensive waveform or stage-count customization would need to look at more complex modulation pedals instead”
