A simple to use, great sounding phaser.

The DeltaLab PS1 Phase Shifter creates a modulation effect that results in sweeping, swooshing, otherworldly sounds. The PS1 will add depth to the sound of any electric guitar or electronic keyboard.

Three knobs let you dial in just the right amount of speed, depth and regeneration (intensity) to find the sound you want. A true bypass switch engages and disengages the effect. The LED indicator shines when the effect is engaged and dims when it's time to change the 9V battery. There's also an external DC power jack for a 9V DC wall adapter.

With the PS1, DeltaLab continues to combine the tonal vibe of boutique effects with outstanding value.

Best Bang-for-your-buck Phaser I have found!

By Stickle

from Ruidoso, NM

See all my reviews

There is no other phaser at this price point that can touch it. I always loved the classic Phase 90 & Small Stone tones and have been very disappointed with more modern phasers in the realm of tone. However, I have always hated vintage 1-knob pedals interface. This pedal blends the two together for a vintagy tone and a modern control setup with a good price. I've played alot of modulation pedals and especially for the money, this is one of my favorites!


Can't complain

This is the best phaser for the money right now. Depth lets you blend in the effected tone nicely, lots of speed options which is shown by the blinking LED (too bad the DD1 doesn't do this) and it's compact and incredibly sturdy. This is my second DeltaLab pedal and I'm pretty sure it's not my last. Definitely stage worthy.


Plenty of bang for less buck!

It's Chinese made but so far I'm impressed. Easily it replicates those classic swooshing phaser sounds from the 70's and for $60 the price is unbeatable! If you want a good sounding phaser effect at a bargain price the Deltalab PS1 is for you!
