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.

Nice looking and perfect for organizing the entry.
I love this little valet! It looks high quality and the compartment sizes are perfect as a drop for wallet, phone, keys and coins. I use mine on the entry hall table.

Very nice valet tray that gives a dresser or nightstand a much nicer look, and keeps EDC organized.
We’ve been using this sandalwood valet tray (with black "leather" inserts) for about five days, and it has quickly become a favorite for keeping the dresser top organized. It sits neatly on our tallboy dresser, staying put without any sliding, which is a big plus. The tray’s size is just right. This tray is not too bulky, but spacious enough to hold keys, watch, phone, etc., basically all the stuff carried in pockets daily. The wood has a smooth, polished feel, and the stain has a beautiful color which gives it a rich, elegant look that elevates the whole setup. What stands out most are the soft, leather-like inserts lining the compartments. They add a touch of luxury and keep items like my watch from getting scratched or sliding around with a slight bump. I also appreciate the thoughtful design of the notches cut out for phone charging cables. Having those notches makes it easy to keep a phone powered up without a mess of cords. This valet tray feels well-crafted and sturdy, though I would not mind it if the compartments were a tad deeper for bulkier items like a wallet. It’s practical and looks far more refined than the plastic trays I’ve used before, and I feel it gives an excellent value for the money, given today's pricing (July 20, 2025). For anyone looking to tidy up their space with something that feels upscale yet functional, this tray is worth a look.
