Professor’s Notes

The PH-2 is peak MIJ Boss: a phaser that doesn’t just swoosh — it moves air and makes the guitar feel bigger, like the whole rig is breathing in time. Mode I gives you that classic, chewy sweep; Mode II gets deeper and stranger without losing the note. If you think you “don’t like phasers,” this is the one that usually changes minds.

Professor’s Tips

• Set-and-forget classic: Mode I, Rate ~10–11 o’clock, Depth ~1–2 o’clock, Res ~9–10 o’clock for that chewy, musical movement that never steals the part.
• The PH-2 secret sauce: use Resonance sparingly—it’s the difference between “expensive swirl” and “too much seasickness.”
• Make it sound huge (without sounding like an effect): slower Rate, higher Depth, lower Res. This is the “recorded guitar got wider” setting.
• For the wilder side: Mode II, bump Res a touch, and keep Rate slower than you think—this gives you that syrupy, almost rotary-leaning sweep without going cartoon.
• Placement: usually after dirt for the most controlled, studio-friendly swirl. Put it before dirt only if you want the drive to chew on the movement (cool, but easier to overdo).
