Guitar World Verdict

You might have to build it yourself, but the sounds are well worth firing up the soldering iron for, with this 2 and 4-stage phaser capable of doing the classic Phase 90 and Mu-Tron thing, and a whole lot more besides.

My fascination with building things ended a long time ago when I played with Legos. Since then, I’ve become more of a prima donna when it comes to assembling anything, but I still know many musicians who love tinkering with and building gear. 

So, for my brethren who fall under the latter category, Mod Electronics has provided them with the satisfaction of building their own pedals and amplifiers with DIY component kits that come with detailed, step-by-step instructions. From what I’ve gathered, as long as you have patience, a steady hand, and decent soldering skills, you can tackle any of these kits.
