I just modded my Phase 90.

Did this:

The first, and most common mod, is to remove the feedback resistor, R28 (24K). This will makeit sound somewhat like the classic script version and pretty much eliminate the distorted mid-boost. If this is not enough, then remove C11 and C12, this mod will remove the pre and de-emphasis (noise filtering).






I'll let you guys know how it sounds. Haven't even put it back together yet.

Re: I just modded my Phase 90.

It takes a lot of skill at bungling to bungle the R28 mod. Just sayin'

I just bought the Script logo version in the first place.

I just bought the Script logo version in the first place.

At the same time it's $80 plus 10 minutes of extra modding versus $130 for the everything already done. I'll save $50 and do it myself. But I understand your argument too.

And also be sure to read the italics at the beginning of that document carefully. There's a rev of boards were that mod will not apply.

(That's my document, btw)

I can tell Astros looking at that Vox head thinking....hey that sort of looks cool on that 4x10. NOT!!!!!!!!!! It looks terrible! Just wanted to make sure you got that straight!

The script version is $99.99 at most online retailers.

I say these days, just buy the EVH. Or do what I did and paint a Behringer.

Still that looks easy enough that I could do it.

Agreed, The EVH Phase 90 is the Ultimate Phase 90! And can be found for ~$70 used.

Removing R28 does not make the $80 Phase 90 a Script Phase 90. There are many other parts that would need to be removed and some changes in the layout.

Agreed the the EVH Phase 90 is the one to have. There's still some tone suck with the bypass on it though, which I don't like. Either make the thing buffered or true bypass, not this so-called "hardwire" bypass that still creates some signal degradation.

AFAIK, the EVH Phase 90 script button only does the "R28" mod, it doesn't make the pedal have the full script circuit. For that, the Custom Shop handwired Phase 90 or the Whirlwind Rochester Orange Box (my favorite, the exact script circuit with LED, true bypass, and handwired board) are two that have the true script Phase 90 circuit. As it was said, you have to actually change out 5 or 6 components to get a later version Phase 90 with the feedback circuit to script specs. Again, I really recommend the Whirlwind Orange Box, it has everything you'd want in a script Phase 90 and more. And, it doesn't need to be modded to get the LED and true bypass switching.

Oh, ok. I don't do much modding to pedals. i find the one that sounds the best and keep it that way.

I do use my ears, and my ears tell me that the script circuit sounds better than the Phase 90 with only the R28 mod, when I modded my early Dunlop Phase 90 (which is identical to the later block logo original Phase 90's, including the same board, through-hole components, and case-mounted jacks, switch, and pot), I did some investigation on Aron's Stompbox Forum (and other sources), and found the complete modding schematic to change it to the script circuit. The R28 mod gets you about half-way there, you have to change out more components to get the original circuit (and the mods are very simple). There's no reason that you can't get into the circuitry and also use your ears to appreciate the difference!. I love just playing guitar, and trying different pedals for different sounds, but I also like to learn about what makes those pedals sound the way they do.

Re: I just modded my Phase 90.

Blasting through a half stack in a noisy club do you really think anyone is going to know the difference, really?

Re: I just modded my Phase 90.

^Nope, will go unnoticed.

But when ya setting everything up together to test maybe alone at home & notice that one of the units is behaving differently, then that can have a psychological impact on the mind, which can carry over to the next gig whenever the odd functioning unit is about to be used. Thus thereby affecting ones playing & then everyone can notice the change/error.

Well maybe not! lol

Re: I just modded my Phase 90.

Again - if you are playing out and the difference in the R28 vs non-R28 phasor affects your playing enough that we all notice it, please do me and everyone in the audience, as well as the band a favor:

Stay home and let a real player play. I'm there to be entertained, and watching some tone snob gear head priss and b!tch and piss because mommy didn't put the right pudding in his lunchbox isn't entertaining.

If you can't walk up there and make it work with a Phase 90 right off the shelf, you can't do the job.
