Phase 90 'still phasing' after OFF???

Hey folks- had just a great Classic Country gig last night at what I'd call a "sophisticated Roadhouse" (actually a nice Tavern that gets rowdy!) and I was using my Phase 90 (the 'block logo' w/R-28 mod) which I got recently, and just use on a few Waylon or similar songs. I noticed that if I had it ON, say to do just a solo section in a song, I swear it sounded like the phase effect would stay ON for 20-30 seconds after turning it OFf... Don't know if there is a stored-up delay in the effect that just needs to bleed out after turning OFF, or if this was just a psychoacoustic thing going on just inside me (no, I was not doing mushrooms:wink:)

Now once whatever song (I was using the Phase 90) was over, the effect seemed to go away. BTW, I had the Phase 90 first in line, even before tuner (and OD) it was just on the floor, running on battery, first....

Any thoughts? This does not really bother me as I like the effect, and it only gets used in a few places, more of a curiosity thing, as to whether others experience the same phenom....thanks, Joe

bump!

"11" or "Waylonfan"- where are you?:wink:

It seems very possible that it was a psychoacoustic (is this a real word?!) thing. Your ears may have been trained by the sound when it was engaged and then you just heard it even after you disengaged the pedal. I have no idea, but that seems like a possibility.

I always swear I can hear some weak phasing after I switch mine off too, but I think I am just hearing things, and after a while it fades.

It should be easy to verify with an oscilloscope.I´ll see tomorrow if I have time to do it.

Go for it!

as I said in my original post, this is more of a 'curiosity thing' than anything else! thanks

so it's phantom phase? Consider me subscribed.

I don't think the std Phase 90 is true bypass, it could be bleeding some of the effected signal even when bypassed, I have had pedals do that.

I agree (I'm OP) about the bypass (which is also why it's first in line, before buffered Boss tuner, not that I really know much about the bypass issues, I do keep my setup simple- I only use 4-5 pedals max) it may be 'bleeding' the whole time it's in the signal chain, but the bleed is only noticeable (to me) when the Phase 90 is ON, then OFF...

I had the same thing with small stone nano phaser. I dunno if it really was phasing after turn off or it was all in my head. With Worm phaser I don't have that feeling - when it's off it's off, done.

Interesting! thanks- will be doing a very similar gig, with the same gear on Wed- am expecting the same 'funky' results:wink:!

Interesting, I have a behringer ph-9, basically the same thing and I have thought I noticed that too, sometimes I think I notice it with my flanger as well.

^^^ I'm just glad I'm not the only one hearing things!:wink: Now I feel better

I've got a CS Script Reissue version and don't hear anything once I turn it off.

And right there the upgrade of your Phase 90 (true to spec) could be the difference maker with this issue- I thought of that...also maybe the "yank R28" mod I did to my Phase 90 could also contribute to the "bleed" but I have no idea about that- but it's probably a cheap bypass issue with my pedal???

Well there are 3 versions of the Phase 90 out there now. Mine is the middle tier version. It has the LED etc. The top tier version is the 74 script reissue. I believe it's battery only with no LED.

Not sure on the differences in switching offhand.

My Phase 90 was actually bought for me by a friend as a late X-Mas gift from a fellow guitar buddy (who was also thinking of getting one, so he bought one for me to try...) , Since I only use it for a few songs and really just one band, I told him to save his $$, and we can just share the pedal (we swap effects around...) He does NOT know I did the 'R28' mod, but it sounds better....

i've been wondering about this a bit more and had some thoughts. my delay has a "trails" switch, when it's on and i shut the pedal off the delay effect keeps working until it fades out on it's own, with the switch off as soon as i shut off the pedal, delay effect is gone. phase and flange are time based effects, could something similar be happening?

another thing for the op, do you use delay? if so that might be what causing it to "linger", i'm not sure it's what i'm hearing because i'm sure i've heard it when not using delay, but i'm not 100% sure because it doesn't always happen, and i can't seem to make it happen (now it will probably never happen again).

OP here! (joe)
I have a Boss DD-3 as my very last effect before amp- but it is NOT on when using Phase 90 (I only use my delay for specific slapback or psychedelic stuff, not as an 'always ON' effect) I only use a max of 4-5 effects (I switch around for specfic gigs), and prefer the Phase 90 before my OD pedal (just sounds better when using both) so my chain is:
Guitar> Phase 90> TU-2 Tuner> OD Pedal> DD-3> amp

I got mine cheap through Bestbuy (thanks reward zone gift certs!). After the certs, I was a lot cheaper than the block logo. At that point, I figured why not and decided on that one over the standard line model.

Happened to me, too!

Our sax player heard it as well. I still believe it could by our idea and not real, can't tell for sure. I got rid of the pedal because it sucked the hell out of my tone when off (which was 99% of the time).

^^^ Could be just an improved bypass these days on the Phase 90 itself, or just the Boss buffers (TU-2 tuner, DD-3) that come after it (plus just a simple 4 pedal setup) but I have no tone suck w/pedal off. Will be using it again tonight, Yay!
