Feedback is an elusive criminal. That’s why you need a detective!

The Feedback P.I is a device that will help you eliminate the threat of feedback on any stage. It combines the three main approaches for fighting feedback all in one box: An active notch filter, a noise gate, and a Vol knob that can act as a PAD. The active notch filter will take care of the fundamental frequencies that are causing feedback. The Noise Gate acts as a life insurance, cutting the signal while you are not playing. The Vol knob goes just a couple of decibels above unity, so it can be used as a PAD if you are forced to use a higher gain amp.

How to use:

Right is IN

Left is OUT

1.- Set the VOL knob at unity (just a few degrees lower than fully clockwise).
2.- Start with the FREQ knob all the way to the right.
3.- Turn your amp and pedals past the feedback threshold. The idea is to intentionally create feedback.
4.- Once the feedback appears, start turning the FREQ knob to the left until the feedback goes away. You’ll likely find a few spots (or a range) where feedback disappears, but try to find the optimal position at the higher end of the frequency range.
5.- (Optional) Set the Noise Gate to 12 o’clock and engage the switch (up position). If your band is loud, you might need to turn the knob further to the right.
Volume: Set the Vol at unity if you are using a feedback-friendly amp. If you are using a high-gain amp, move the Feedback P.I to the end of your chain and set the Vol knob to 12 o’clock. This will turn the pedal into a PAD that will help to reduce the gain of the amp.

FREQ: This knob sets the frequency affected by the notch filter. It ranges from 400hz to 7000hz. The goal is to find the highest offending frequency. This will better preserve your tone.

ON: Turns the noise gate on or off. When off, the noise gate is bypassed.

GATE: Sets the threshold of the Noise Gate.

Right is IN

Left is OUT

The power consumption of the Feedback P.I. is around 20mA. It doesn't need much power to run, so any 9V DC (center negative) Power Supply should be enough to power this pedals and a handful of others.

Great for acne prone skin
Size: 5 Fl Oz (Pack of 1)
I have very acne-prone facial skin that clogs up easily, so I’ve always been cautious when it comes to using sunscreen. Most formulas tend to feel heavy or greasy and often lead to breakouts—but Neutrogena sunscreen has been a refreshing exception. This product is lightweight, non-greasy, and doesn’t clog my pores at all. I’ve been using it consistently and I’m happy to report that I haven’t had any breakouts or irritation since I started. It absorbs quickly and leaves no white cast or sticky feeling. If you're like me and struggle with sunscreens causing acne or clogged pores, I highly recommend giving this one a try. It protects without the usual side effects and feels like you’re barely wearing anything. Definitely a keeper in my skincare routine!

Long lasting
Size: 5 Fl Oz (Pack of 1)
This goes on easily, has great coverage, and lasted longer than I expected. Even with sweating I was still fully protected. The best part is it doesn't feel sticky or oily once it has dried down. The first few minutes after application it does have a bit of an oily feel, but that goes away relatively quickly. I have very sensitive skin and I often either break out or get irritated skin from a variety of beauty products. This is the only sunscreen that hasn't made me feel itchy or uncomfortable. I am going to buy the two pack next time.

The only sunscreen I can get my dad to wear
Size: 5 Fl Oz (Pack of 1)
I love this sunscreen. I use it when I am too lazy or in a hurry to apply sunscreen from the tube, or when I am reapplying. I also like to use it on my legs because it is so much faster than applying tube sunscreen. This is quite effective and offers almost as much sun protection as my tube physical sunscreens that are SPF 50 with a high zinc oxide content. My dad, who has fair skin and always refuses to wear sunscreen, even though I can see him getting burned - actually agreed to apply this sunscreen because it is not yucky and is actually a pleasant application. He even said he liked using it, so I ordered him a can of this and I think he might start using it on his own! I am so thankful I found something that he is willing to use! There is no white cast at all and does not require rubbing.

Light spray with pleasant scent
Size: 5 Fl Oz (Pack of 1)
I really like this product. It goes on lightly, it’s not greasy and the smell is nice. Although, I noticed that even with multiple applications I still got a slight sunburn. For this reason, I wouldn’t trust it for a long day out in the sun. It’s better suited for an average day with light to moderate sun exposure.

Protects your skin better than other brands due to Helioplex Technology
Size: 5 Fl Oz (Pack of 1)
Had Mohs surgery after they found a spot on my bald head. The office gave me a very short list of things to do to protect my skin going forward. This was on that list because it contains Helioplex Technology. Now if they are going to suggest I use helioplex technology to protect my skin then I am going to start using it, and now. I have been using it all summer. It works well, my skin feels great after using this sunscreen. No greasy feel. The spray is fantastic, no slimy hands from spreading lotion. Best of all it last for a long time on the skin. We should all be wearing sunscreen and this one has the newest technology. Neutrogena for the win!
