BOSS PH-3 Phase Shifter Pedal Review by Sweetwater Sound

Get the BOSS PH-3 Phase Shifter here:

In their iconic stompbox form, BOSS does it again. The PH-3 Phase Shifter, in stunning lime-green, serves up classic phase tones and a lot more. The 4-Stage mode is is very familiar sounding while 8, 10, and 12-Stage modes each get progressively thicker and chewier. Rise and Fall modes add their own new twist and Step Mode is a very welcome surprise. I love the randomness of the pattern.

Rate, Depth and Resonance offer plenty of sonic shaping; the addition of Tap Tempo and the EXP/CTL input put more flexibility and on-the-fly creative control. Great sounds, lots of options and rock-solid Boss quality.

Thanks for watching!

Dan Jackson says:

If you rotated it 90 degrees clockwise we could actually see what the controls look like rather than the side of the unit.

Raz Rojas B says:

He does look like James May but, he freaking rocks in all these demo videos, this pedal sounds so rad!

Ric Di clemente says:

Why if you demo pedals do you need distorted sound people can’t get the true sound of a pedal

I appreciate the direct stare into the camera as we’re listening to these noises. I was feeling a bit too comfortable watching this.

Tobias Johnson says:

The phase sounds like part of the theme from The Warriors

horrible nails

Mark Hollstein says:

For functionality, this pedal wins out among its MXR predecessor. Aside from the 74 script or EVH phaser, I can’t see any reason not to buy this pedal…

Thibaut Vandame says:

idk why , but this guy makes me think of roger from american dad lol

Ethan Yong says:

The step mode sounds like it has a very quick gated effect so that the phaser is continuos but only a very quick gate

Thiko Seeri says:

so the name is phase shifter , pedal that im looking for

Domi Hunter says:


Neal B says:

MXR wins.
