Simple pedal, with a very subtle tone
Disclaimer: I have a Dongeomac clone of this pedal
The Phase 45 is a very subtle pedal to my ears. Very much a vintage tone, but luscious just the same! If you're looking for a phaser that won't overwhelm your clean tone but lend all the phaser-y goodness, this is the pedal to get. Single knob pedal makes it super easy to adjust on the fly if you need more of the effect.
The only reason it's four stars is because the more subtle tones may be a turn off for some, and sometimes it feels like there isn't enough phaser for my tastes, but perhaps that's due to my bad habit of diming everything at first. I bet with some fine-tuning, it'll be lush and subtle!
Artist usage
Add artist
Steve Jones used an MXR Phase 45 on "Anarchy in the UK." In an interview with Ultimate Guitar, he said: "I only used one effect pedal and it was on Anarchy In The UK, it was a MXR Phase 45. That was the only thing I added on my end." He's always been a no-frills, simple rig guitar player, so his primary sound with the Sex Pistols was his white Les Paul through a cranked Fender Twin. Some websites mistakenly state that he used an MXR flanger, but he didn't use one, and the interview here shows he himself said he only used a Phase 45 & it was only on "Anarchy in the UK."
