The 'Phase' Switch - What Does This Button Do?
Вставка
- Опубліковано 31 жов 2018
- If you have an electro-acoustic guitar, then it most likely has a button on it marked 'Phase'. On the face of it, this button doesn't seem to make any difference to the sound, so what exactly does it do? In this video, Dave explains why this button is so important.

Somebody give this man an award, a noble peace prize or something. Brilliant!
Agreed
i've been asking a lot of people about this, and i only got the answer because of this. thanks!!!
This was super helpful! I have been trying to learn this for so long!
Thanks Dave. I just picked up an Ibanez GA35, and the only control that was not explaned was that "phase" switch. I had an idea of what it was for and you just confirmed it nicely. Thanks again.
What a science!!!! I was NOT able to find anything about phase switch functionality at anywhere. Thank you for the clear scientific explanation.
Thank you 😊 I appreciate your time and support
Thank you for the help. Ran into a feedback issue yesterday so this will help.
Brilliant info - just what I was looking for - thank you for being such a reliable source of knowledge and information! xx
Fantastic explanation, thanks!
I have an acoustic bass with phase button and had NO CLUE what it was for!
Thank you so much, I really learned how to manage this on my pre amp now !! Very helpful and great post.
Thank you for the Detailed Explanation! I'm a long-time Guitar Player. However, I've never really known what the Phase Switch actually did. I've seen the button on many Acoustic Guitars & yeah, like you mentioned others have said - It doesn't Change the Sound of the Guitar. In your video I've learned - It's Beneficial to Control Feedback. Something I'll be Experimenting with in the Future!
Thanks for the Demonstration, I found it very informative and easy to understand.
I was searching for it and i got this it's really help me .. thank you.
Thank you this was really helpful. Explained simply, that even I, with no technical knowledge, could understand the principle easily 👍😊
Great explanation of this Switch - to the point and pretty easy understandable - to the point! THX!
Very handy Dave. Thank you. Greetings from Athens Greece mate
Thanks Dave... Did NOT know concerning Phase Switch on Pickup Controls... Many thanks... ☘
thanks for clearly explaining this, now I understand it works
Thanks dude! Clear and interesting explanation
Best explanation I have ever heard. Thank you
Cool info. I constantly have feedback problems with my electro acoustic .I use a sound hole rubber . (Noisex lol) .I didn't realise that some preamps had a phase switch my yamaha ntx 700 hasn't.is this feature only on certain guitars and if so is it possible to fit a preamp with one.thanks for your videos very helpfull
Best explanation I got so far, thanks
This is awesome. Thanks phat!!
very good information!! I also found out that sometimes the phase switch eliminate other problems. I was having a "cutting Out" issue when I turned my on board tuner on and off during a performance. after playing with the amp and guitar I realized I had a lot of noise. i pushed the phase button and the noise and the problem went away.
thank you so much you explained it very clearly
Great video even today! I'm wondering though, if it only seems to help, why is it not a feature enabled by default, why is there a control, is there any reason to disable it?
thank you that was very helpful and informative
Thank you! Great explanation!
Really helpful, thank you so much. I would like to have an information about fishman new system "flex blend "( how to use ).if it is possible .
Whaaaat?! That’s brilliant!! Thank you!
Thanks for this answer.
Wow! I get it now and I clearly did not before watching this video. Thanks!!!
thnx for this man . its so much interesting . !
I don't understand why the phase switch doesn't come standard on acoustic preamps. Does it affect the sound quality in any way?
Right on! Thank you!
Merci ! Thank you !
Buena explicación, de verdad gracias
Does it only work if you plug in to an acoustic guitar amplifier? I gig plugged into a DI box straight to the p.a. The Phase switch works on stopping the feedback but I notice that it changes the eq/tone of the guitar too making the sound thin. I would have to re eq again but would encounter another frequency that introduces feedback. I would reverse the phase again but it just go back to the initial feedback problem. What should I do?
Thanks for this!!
Thank you!
TY for that added info (y)
Ahhh good explanation! Thanks!
Thank You!
Now that's the magic trick!!! Thanks :)
So, why is phase function not permanently switched on, without any switcher at all? Does it effect in any wrong the sound of guitar when is on? May I have phase button press in all time? thx.
Thankyou sir...
nice video man
Nice one!
Thanks, great video : )
Thank you
what does the contour button do ? can’t find an explaination anywhere
Thnks soo helpful ☺️
Thank you...
In order to save energy, I was wondering if it's better to let the phase button out and activate it only when the feedback ocours. Is it going to make a difference in the battery life??
It makes no difference - remember that the battery will be being used for the preamp regardless of which way the phase switch is set.
Excellent !!!!
Gracias.
Thanks a lot for the detailed explanation
Can you please explain how notch control works and do rubber sound hole covers help anti feedback on stage?
Good questions. I'll do a video about this sometime - may be a little while as I'm just about to take a break for Christmas & new year holidays
Here you go... ua-cam.com/video/xJld_paXREE/v-deo.html
Very well explained. Also, I used to listen to a relatively well known Christian band called Phatfish over 20 years ago 😆.
so it's just to avoid feed back?
So, how do you turn it off and on? When is it in phase and out of phase? One way always sounds a bit off. So which position should we generally leave the phase switch when we are no using it? More info please. Thank you. sounds
It isn't an on/off type of thing. It's either outputting in one phase or another. If feedback isn't a problem then leave the switch as it is. If feedback is an issue then hit the switch to change the phase.
thanks
Does it change tone? Does it lose that quackiness when putting the guitar in phase?
No. The effect you're thinking of is when you change the phase on an electric guitar pickup - this is something different, about suppressing feedback.
Tanks
What to do in case if we don't have a phase switch?
When setting the equalizer settings what is the seagull shape
I think the thing you're referring to is the way the lines on the EQ curve sweep along a line and down to a point - think about how you'd draw a simple seagull in flight with just a couple of pencil strokes
Just wondering what's with middle finger pointing? Kinda seems like your flipping us the bird. Just asking. Great answer I've been wondering for ages what that was for. Thanks
Force of habit - most of the time I've got a pick between my thumb and index finger, so middle finger gets used for pointing.
@@PhatPhishGuitarStudio Yeah I kinda figured. I tried fiddling with that button, got some cool effects.
it kills feedbaack. And reverb!
Not to be rude but to save others time the phase just cancels the original sound wave & reverses it so there is no feedback from guitar to amp vice verse.
Hello, I have a problem with an acustic used guitar payed € 150 - Cort MR7 OFX NAT Fishman prefix plus t - it souds always and only like an electric guitar, I tried everything (changed battery,amplifier, cable) but there is absolutely no way to get a simple acustic sound. More, the sound is not constant at all, it comes and goes. Any advice to solve the problems ?
Massimo Di Gennaro Change faulty parts.
might be a) overload of the amplifier, b) the pick up is not fxed properly (under the bridge).
@@raccoon6072 Really thanks
idk if i have an electro-acoustic or an acoustic electric guitar?
please my fishman not register the bass sounds in my folk guitar which is the reason
My LP Muse has a phase switch but it doesn't remove feed back.
That's an electric guitar so what that switch is doing is flipping one of the pickups from in-phase to out-of-phase to give a different type of sound. On an electric guitar phase refers to the electrical phase of a pickup, whereas on an acoustic guitar it refers to the phase of the output sound.
@@PhatPhishGuitarStudio THE phase switch on my LP is on the bridge volume and my hummingbird acoustic electric has a slide switch that clicks in the center.
I've got a couple of electric guitars here with phase reversal switching. I'll do another video sometime explaining how they work and what they're doing with the signal
@@phillipholt6005 Here's a new video talking about phase switching on electric guitars vs acoustics... ua-cam.com/video/Xd0f_6P1wlA/v-deo.html
Wow. Another 30 seconds and this guy would have told the secret to the GUT (Grand unified theory that combines general relativity with Quantum physics) that both Einstein and Neils Bohr grappled with. Anyway, why phase or not is dealt with in the 12 mighty seconds from 6:00 to 6:12. Rest deals with highly complex theory of why sound waves travels the way they do and not otherwise!
I like to take the time to explain why something works so people understand it....and I certainly wouldn't call what I talk about here as "highly complex theory" - it's fairly basic physics of soundwaves, which makes it far easier to understand how and why the phase switch works.
i thought it was a phaser, haha, i just think it didn't worked on my mono amp lol
Note: It may change sound of guitar, it may decrease volume of lower frequencies, "overcompensate" (throw the baby out with the bath water :)). It isn't something very bad though, much better than feedback noise.
My music is rooted in feedback, this means that knob is useless for me. I wish they made me a special knob that gave me more feedback. 😂
Why would we even have a phase switch then.. I bought a electric acoustic combo because I can only afford one guitar but I want to play metal and normal guitar. I've only owned electric guitar before. Nobody has answers for me.
Did you watch the video? The phase switch eliminates feedback when playing an acoustic guitar through an amplifier.
@@PhatPhishGuitarStudio that's my point why would we ever want feedback... It shouldn't be a switch on an acoustic electric guitar it should just be always on.. if it's not plugged in then no worries if it is plugged in it should be opposite phase all the time. Thats the point of dual coil pickups on an electric
You can't compare feedback from an electric guitar and feedback from an acoustic guitar - there are differences in how feedback is produced in each case.
For an acoustic, feedback is undesirable, hence the switch to eliminate it. Which phase feedback occurs in varies based on various factors - hence the switch allows you to set it according to the conditions in any specific situation.
Incidentally the point of dual coil pickups in an electric guitar is not to eliminate feedback - it's to eliminate hum caused by electrical interference. You can get feedback from humbucking pickups quite readily with adequate volume.
Why everyone who make video swallow? I can talk with hours and will not swallow!
Sorry but this could have been explained in two minutes without the waffle.
Thanks a lot! Great explanation!
Thank you!
