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 pillows, needs more filler tho!
Size: King Size Pack of 2, Color: White
Partner says it's the best thing that's ever happened and has helped his back/shoulder pain tremendously. I personally think it needs to give you more fluff or whatever the filling is. Because the tiny bag that comes btwn the two was not enough! However, still comfy, filling is nice and fluffy like a cloud.

Takes a few minutes to fluff up and inflate after opening. Nice fabric. One side is bamboo and one side is cooling. Looks high quality.

Love them!!

Ok I normally don't leave reviews but I had to on this pillow. I was looking forever for a pillow and was nervous about buying one because you know how that usually goes when it comes to buying pillows. They arrived compressed but when you unwrap them they blow up to be a heavy duty pillow. Firm but not too firm. I don't like super soft pillows that you can roll up in a ball with one hand, I like a pillow that gives support and these do just that. They are cooling as well they are pretty for a pillow with the unique design. If you are in the market for a pillow and reading this THEN BUY THIS PILLOW & come back to tell me thank you. I promise you will NOT be disappointed. No I didn't get paid to say any of this. I wanted to give a honest review where it deserves one! You will not be disappointed! Thanks for the fast over night shipping as well. Not to mention the pricing is on point. I can say right now you will not find 2 pillows of this quality & price.
