"That Carbon Copy is the best delay I've ever used, hands down, no contest... The Cry Baby wah-wah pedal is more than just another piece of gear on my pedalboard. I purchased one the day I bought my first guitar and have never played a show without in the last 25 years. The same goes for the MXR Phase 90, and the mustard yellow Distortion+. It's at core of my personal sound, I use it as lead channel, I use it in a set position as much as I use it in an up and down motion. I couldn't live without it!"more
There are lots of phasers around, but somehow almost everyone ends up with Phase90. No other phaser sounds so natural, lush, warm and sits so great in the mix on cleans, overdrive or hi-gain distortions. Single knob control makes it extremely easy to use and offers lots of tones just right away - from subtle phasing to extreme psychodelic sounds.
However there is one minor flaw - current version, A.K.A. block logo has an awful volume boost which is quite annoying in some circumstances. Some people just get along with it, some do not. For those who do not a simple mod can be done - literally 5 minutes of work. Open up the pedal, find the R28 capacitor (manual on the web) and snip it. Problem will be gone, no more boost, just pure phase shifting.
This pedal is definitely a sword hidden, when you use it everything changes, it is something that really changes the song, not only your tone; i can't imagine my pedalboard without it.
I have found very few uses for the Phase 90, but I've been able to truly create an amazing sound when I've felt the ability to incorporate it into my playing. In my experience, I've been able to use it in three situations: (1) Hendrix-esque soloing with very heavy distortion placed on top of the Phase 90's intensity set about halfway, (2) Effect-heavy lead lines in dark, weird alt-rock music (intensity set between halfway and full), and (3) Open, subtle chords played lightly over light pads (intensity very low, almost at 0).
