Owner Insights
We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Boss PH-1R Phaser.
Features and functionality
-
The PH-1R offers a range of phasing from 100 ms to 16 seconds, optimal between 11 and 1 o'clock for subtle effects.
Source -
The PH-1r is noted for its lush and rich sound, though it is less subtle and transparent compared to the MXR Phase 90 or 95.
Source -
The MD-200 offers a "shiny" phaser sound, which some find artificial compared to the PH-1, suggesting a digital brightness in multi-effect pedals.
Source
Comparisons
-
Owners note that the PH-1R can mimic a vibe effect, unlike Phase 90s and Small Stones, but doesn't reach "zero point."
Source -
The Boss PH-2, at a lower price, offers smoother psychedelic tones with mode 1, while mode 2 provides a more pronounced sound.
Source -
The EHX Nano Small Stone is highlighted for its warm or intense resonant tones, offering an alternative to the MXR with a lower frequency sweep.
Source -
MXR Phase 95 reportedly comes closer to the PH-1 sound than the MD-200, despite differences in tonal characteristics.
Source
Use cases and applications
-
Best used with resonance at 7-8 o'clock for subtle phasing, achieving a vibe-like tone with low resonance and high depth at faster speeds.
Source -
The PH-1r is preferred for swells, washes of noise, and adding texture, making it ideal for psychedelic and shoegazey styles.
Source -
The MD-200's inclusion of a Slicer effect evokes Four Tet-like sounds, appealing to experimental music creators.

Very nice but not recommended for live use
Very nice sounding pedal ! But I can't recommend it for live use. One day on stage, the soundman said to me : "Maaaaan... I can hear a kind of wobble... don't know where it come from". The Phaser was OFF. I turned the speed button and we heard the wobbling sound going slower or faster in the speakers. So it is NOT a true bypass pedal (like all non-WAZA Boss pedals). So I bought the Retro-Sonic Phaser : true bypass, based on the Boss PH-1R and the 4-stage Script 90 circuit.
