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!
