    Phase is a fairly complex concept as a whole (https://en.wikipedia.org/wiki/Phase_(waves))

    In the context of Phase Inversion for fighting feedback, you're essentially altering the sound wave's relationship with the room that you're in. By inverting the guitar's wave by 180 degrees you can take a guitar that is having issues with feedback, say on a low G or F#, and shift that feedback frequency to a less common note.

    Most guitar's will feed back at the guitar's top resonant frequency, so changing the phase can often give you quite a bit of additional volume before feedback. Conversely, changing phase in some rooms may cause additional feedback.

    I hope that helps.

    Could someone please explain the phase toggle button to me, is this to do with feedback cancellation or with the actual sound/tone?

    I agree with Caleb, nice guitar.

    Like you, I had trouble with adjusting the Anthem at first. When at home I would dial in my guitar in a relatively small space. My Taylor DN5 is a loud projecting guitar. With my monitors at normal, in a small space, I thought I was dialing in this sweet tone, but instead I was hearing my actual guitar sound blending with the pickup sound. I would take the guitar to church and play in the wide open space and........Yuck! either dark and muddy (mic trim very low) or steely and nosiy (too much mic trim). I was getting a bit frustrated. Once I figured out the issue I was able to use headphones and a loud monitor to hear only the anthem sound and adjust what was actually eminating from the Anthem Pickup. Now I the guitar is fun to play plugged in thorugh the entire mic/pickup mix.

    I hope you have many years of enjoyment.

    Sincerly,

    Ed
    Makes perfect sense, thanks for the tip!

    Thanks Caleb! Now sounding great too, it was one of those hidden gems gathering dust at the back of a music shop, took her home and added some serious tlc, and also the fact that it did not had a factory installed side-mount pickup interface made the LRBaggs Anthem installation such a clean installation and a breeze.

    Just to clarify this, the mic will never carry any sound below 250Hz, and so will never carry 100% of the signal. So even if the mix is set to the full mic side of the blend, the undersaddle will still carry 250Hz and below. That's how the Anthem is designed, for added feedback resistance and a stronger low end response.
    Got it thanks! I've managed to make that last little tweak with the mic trim pot with the use of proper philips screw driver and I'm now happy with my sound.

    Do not be discouraged. The system has some flexibility of sound that is cool to use. You will figure out what is best.

    About the trim tool. Is the included tool a small flat head or a phillips (+) style jewelers screw driver? The Anthem installed on my guitar is easy to adjust with a phillips head jewelers screw driver like one used in cell phone to tablet repair kit rather than the flat head jewelers screw driver indicated in the instruction manual. I can easily feel the phillips head lock gently into the trim screw and adjust the full range of the trim; about 3/4 rotation max.

    Let me know if it helps.

    I guess you're right my friend, it does provide the extra flexibility eg. extra punch in live performance, but in recording I prefer the acoustic sound turning the blend control all the way to the neck, so I guess it gives me about 97~98% tru-mic as I still can hear some under-saddle coming through.

    In regard to the trim tool, the plastic flat tip might just have softened with the couple of tries thus not turning the "+" screw anymore and perhaps just slipping.

    I will try your suggestion of a phillips head screwdriver as I need to increase the intensity ever so slightly then it should be fine.

    What boggles me is that yesterday I had a complete different sound from my guitar (even unplugged), the guitar felt very "dead" and closed-in, not sure why.

    The TUSQ saddle and bridge-pins upgrade made a huge different in sound, but I'm still battling to get "that" tone with minimal or no "quack". I tend to regret not going for the Lyric instead and now I'm having difficulty to turn the mic gain/trim pot with the included tool, hope I did not damage it with the amounts of tweaks.

    Thanks guys, I'm awaiting my Tusq saddle and bridge pins to arrive tomorrow and will adhere to your suggestion. I undertand this upgrade will also make a difference as I currently make use of a cheap plastic interim saddle which I used to get the height to a nice action.

    The original nuBone saddle was sanded too low due to the original Fishman thats' about 4x the height of the Anthem's piezzo strip so I could not make use of this saddle anymore.

    Thanks, can't wait!

    I completely agree. Set the mix to the mic side, plug directly into your amp or mixer, with EQ set flat. Then you can make adjustments to the mic trim to get the mid and high frequency response to match your guitar. You can add more mic for extra brightness or take some out to darken the signal from there. I usually prefer to just match it to my unplugged tone though.

    Adjusting the Anthem Tru Mic Trim to match your guitar

    Andreve,

    I would suggest starting with a clean signal chain. In other words plug in the guitar directly into your monitor or amp with all eq and volumes set at zero or half. Then being working the mic trim from the lowest setting up or the highest setting down until the guitar begins to sound good with the mixer set all the way to mic (towards the neck). Once the guitar mic trim is set then you can begin to mix in the pickup to taste.

    I hope this helps. Anyone else have tips for dialing in the Anthem Tru Mic?

    Hi, I've just installed my Anthem to my Guild F-150, but not sure how to properly setup the mic pot mix and where to start. With the blend control fully to the neck position I suppose to be a good starting point, what sound/tone/presence should I look for while adjusting the pot with the included tool?
