Recommendations for Phase project

[ElectroFreak]

I've seen quite a few schems out there for diff phase pedals; can anyone out there that has built several of them recommend a nice versatile one?  I've seen a lot of small stone and MXR schems, and several others here and there.  Also, I wonder how hard it would be to make a combo phase/flange circuit?

I'm gonna build a "Univibed" Phase 45, anyone who's build one loves it... It'll be nice to have a choice of vibrato and phase like a univibe

Not sure about the phase/flanger though ...

I've built a couple, so I think I'm qualified to comment. It really depends on how lazy you are, and how experianced you are.

Any JFET based phaser (Phase 45/90/180) will be really hard to do if you are lazy, as to match the jfets correctly takes some time, and people usually don't sell prematched sets. These are the simplest construction wise.

The OTA phasers (ex, Smallstone, Ross Phaser, Bad Stone etc...) are rather complex builds, as usually the boards are crammed full of stuff. These tend to be easier to make in the long run, as no matching of anything is required.

If you are both experianced and not lazy....the one I like best is, of course, the neovibe/univibe. There are at least two different verified layouts for it, and it is not by any means a simple build. The power section is a pain to deal with, and generally both projects have instructions that assume you know most of the basics of pedal building. Not recommended for the faint of heart.

I know there are many more phasers, but those are the common ones, or ones that the saner people build...there are ones available that are much much more difficult to build such as the phaseur fleur, but since I haven't built any of them, I can't comment.

As for phase/flange...none that I know of do that by stock...so you may have to box two things together...not too fun.

Yup! ... just retored a Script Phase90 ... I found a dead op-amp and a dead JFETs. I didn't know about the matching, and couldn't figure it out! .. all seemed right but no phase... many thanks to the help I received here! ... Very important! MAKE SURE THEY ARE MATCHED

Ohh! Sounds interesting! What sort of work do you normally do with pedals? How much work have you done with pedals (I could help you choose a good project that's not ridiculously hard, but not much below your level also).

Still not an "easy" build, but you can omit the transformer from the neovibe and just use an 18V external wall wart, which saves you some trouble.

I think I have decided to try a Small Stone with the univibe switch mods.  I haven't built much in about a decade; now I'm getting back into it again.  I built a Gov'nor clone but did it on perfboard.  I recently got all the necessary stuff to etch my own pcbs and have made my first 2 aready.  (I have a whole bunch of projects I'm working on, Orange Squeezer and an MXR Noise Gate are the boards I just made).  Only problem is now I have to go buy a drill press!  Back when I made my pcbs a decade ago the schems I made by hand and the pads were large enough for a reg size bit; with these iron-on schems (process worked great with photo paper!) it's a whole different story.   Thanks for all the input guys!

I suggest the Ross phaser.
