Just like 1974 model I once owned ...

Perfect tone recreation of the original ... I owned the Phase 90 and Phase 100 back in the day ... if you want to run this on DC power (not battery) ... Zvex sells a bottom plate which has a battery clip inside and and 9v center negative 2.1mm plug on the outside, it's not cheap though ... I placed this pedal on my pedal board using this technique, works perfectly!

Good Pedal

I originally tried out the EVH90 Phaser and thought it was a good pedal that worked well and had a really cool paint job, but I returned it as I was intrigued to know how the '74 would sound and I dug the retro thing as well. I've been using my '74 Vintage Phase 90 for a little while now. First off, it's not really difficult to get the battery in like some people have commented. Putting the battery in with the wide side facing out - YES, then it'd be tough to get it in, but sideways, it fits snug with a little finessing of the foam. The sound of this Phaser is really, really good and I like that it has a hand-wired circuit board. I'll give it some time to consider if it's worth modifying to handle AC power which is an option should unplugging the cords to save the battery become a pain over time. This pedal is different then the EVH90 - better, not necessarily, but different in a warmer and subtle way, especially when turning up the effect - it has more of a Leslie speaker vibe to it. Sweetwater = Awesome Service!

'74 Vintage Phase 90

I almost passed on getting this one, because it doesn't have the LED or the AC adapter....However, I am really glad I got this one. I know when it's on, so the LED is not a big deal. As for the connection, well my voodoo pedal power came with a battery connection cable, and that works just fine. I did use a small file to make a notch in the lid for the cord to pass thru when the unit is closed, but it was no big deal to do this, the metal is pretty soft This Phaser is just really nice and smooth, without being too much's really great!

MXR '74 Vintage Phase 90

The reviews you read here and elsewhere on the internet are true about this pedal. It is that great and it is the sound you've heard on albums. This is what Eddie Van Halen was using on those first iconic albums. It is very subtle, but magical. I bought a Hammond orange case and notched a hole out of it's base and it fit perfectly on the bottom of this pedal. I did this to avoid ruining the Phase 90's base plate. I run the battery adapter by 1 Spot out of the hole and power it with the 1 Spot adapter, so I don't have to worry about changing batteries. I tried it with both a battery and powered by the 1 Spot and didn't hear a difference. I'm running this through the EVH 50 watt 5150iii and a Marshall 1960A cab. If you are looking for that vintage phase 90 from the 70s, this is the one to buy. I love it!

Well worth the money. I use this 90 for guitar, mandolin, bass and keyboards when applicable. It's just got that sound I hear in my head that transfers to live and recorded situations. I own a few different MXR Phase 90's, but this one is smoother than the rest. I don't have this in my pedalboard rigs because it doesn't have an external power supply (it's to much to pull it off of the Velcro and unscrew the back to replace the battery etc.) So that's when the other 90's come in handy. But, when recording or playing that special live gig... this is the one to have.
