phase 90 vs. EVH phase 90 vs. byoc phaser


Recommended Posts

whats is your opinion? i am getting a phaser, i just dont know which one. I like the original, had it but i sold it for something else, but now i miss it, only thing is it sounded too overpowering (especially with distortion). Ive tried other phasers, and they all seem to be like that....that is why i added the byoc to the list, it has a "volume" knob. and i tried the evh, i thought it sounded sweeter and more rounded than the original phase 90. whats your opinion?

 

BTW: original phase 90 = reissue (the ones you buy at gc for $80)

I ordered the '74 reissue phase 90 on Saturday from GC. It should arrive sometime this week. The standard Phase 90 was really good after doing the R28 & C11/C12 mods. Unfortuately I blew up both of mine by using the wrong power supply. For the past few months I've been using the Behringer PH9 (which is their EVH clone) with my Rhodes and it sounds good for $30.

the r28 mod is just cliping the r28 thing right? what are the other two mods you mentioned?

The RI phase 90 which i think is what you said you had are more overpowering. I have an original (non RI) and an EVH, the EVH with the script feature one comes very very close to the real thing and is more transparent so to speak. They are also making a model that is a scipt RI, supposedly the same as the EVH script function, but without the EVH design.

Good luck

i just had a look at byoc page again. the new version has a depth knob, not a volume knob. if its turned full clockwise it sounds like the script logo phase 90.

 

i have an old version byoc and i love it, ditched thwe ibanez pm-7 of the board for it.

yep it adds a bit of volume, but its not much and i don't care

Clipping the C11 and C12 capacitors.

 

I found out about it from one of the HC user reviews. Here's what Ravi writes in his review:

 

"I went about doing a couple of mods to this pedal. The R28 mod where you just remove a resistor from the signal (see previous poster for sound review there), and the C11 and C12 mod, which just involves the removal of 2 capacitors from the signal path. These are the input and output caps (as far as I can tell, I don't know much more about electronics than basic understanding of a schematic). When you remove these, it gives the effect more headroom, which means you can hit the effect really hard with your guitar signal, and it shouldn't clip at all now (or at least, very little).

 

 

And that's exactly what happened - I now have a Phase 90 that has around 80% of its distortion gone! I just pulled out some pliers and clipped one leg off the resistor and each of the caps and bent them away enough so they wouldn't touch the board. This way, if I decided I don't like it I can just solder it back together :).

 

 

So here's how to do it:

 

 

R28 - Just above the output jack, its the first resistor there, runs east-west across the board, and is slightly offset from its brothers above it. Just clip the outside leg.

 

 

C11 - This is located on the top, right-hand side of the board. It runs north-south up and down the board. It's right on the edge of the board, and it's between the input jack and another, bigger capacitor.

 

 

C12 - Is on the lower, left-hand side of the board. Just below the output jack is a series of 3 resistors...C12 sits just next to the last one, and it runs east-west across the board. It's sort of between the output jack and the footswitch.

 

It seems a little brigher now with these mods, and definately distorts less. The Phase 90 HATES high output pickups, so single coil guys will love it. If you have a Phase 90 and are at all unhappy with it, try these mods before you get rid of it...they're not hard at all to do, if you can use a pair of scissors you can do these! If unhappy then, sell it or whatever, but at least try. The mod is a definite improvement!"

 

It certainly worked for me. Too bad I blew both up using a walkman power supply by accident on 2 seperate occassions! Yes, I'm an idiot.

 

I'll have my '74 reissue in a few days tho!

I made a byoc phaser and really like the depth knob (and the tone as a whole). The problem with the pedal is it has a really bad pop when engaging the effect (worse than your typical TB pedal).

 

I've never used one, but what about a Phase 45? A 2 stage phaser such as that should have a less pronounced effect.

so you cut the other two (11 +12) completely off?
