It's an absolute classic.

I love this phaser. It's simple to use and does exactly what it's supposed to. My only complain is that it boosts the volume a little bit when it's on. I have placed it in my fx loop of the amplifier to see if the problem persists and it does. Still it's a very small boost and most people would not care about that issue. Either than that its the absolute classic.

Hooked On Music

When I was a kid my friends sisters BF turned us on to a lot of music (Partying too !) One of the things he hipped us to that really stuck with me was the Pat Travers Band, and the record he played all the time was the live on from 1978 or 1979 "Go For What You Know" Well years later in a club after a soundcheck I was talking with a sound guy who said Travers used to use the "Script 90" so when I switched to guitar from bass it was like the second pedal I bought. Phaser is kind of like the older sister of the Flanger, not as short of a skirt, and not as tight of a body, but y'all can talk about stuff for hours...HAHAH EXACTLY !! Must have for that 70's rawktastic sound...

Stunning!

Oh joy this thing is just lush!! An immediate inspiration tool! Keys and vox also sound great when run through it. I even ran an overhead on a snare through it!! It's gold 👍👍
