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.

Best Knife Block Set For Any Kitchen
Size: Steel King 15Pcs 10.4"×7"×15.4"
We ordered and love the BRODARK Kitchen Knife Set with Block, Full Tang 15 Pcs Professional Chef Knife Set with Knife Sharpener, Food Grade German Stainless Steel Knife Block Set Steel-king Series. This set is one of the best purchases we've ever made. We purchased 4 other brand sets and sent them back due to poor quality, etc. One set cost $299 and was not as sharp or solid as the Brodark, and had straight uncomfortable handles. Our new set is sharp, well-balanced, and the handles have a solid, comfortable feel and look great. The quality block looks very nice and has a sharpener to boot. The blades after washing look fantastic. For under $100 this is stupendous value and product (regardless of price). One set we ordered was from the famous German brand and it had knives missing and the steak knives had tiny handles; we sent it back.

Great knife set
Size: Ivory Series 15Pcs 14.43''×9.36''×6.63''
Overall a great knife set. Well built and craftsmanship, excellent sharpness (we’ll see over time) great looks and value. Would have liked for this color to be available in the bigger set of 8 steak knifes. Word of caution with this or any other knife set, DONOT PUT THEM IN THE DISHWASHER OR LEAVE THEM OUT TO DRY! YOU MUST CLEAN AND DRY THEM AFTER USE, If not they will have water spots which will be hard to remove or worse they’ll get rusted.

Very nice knives for the price, with additional options in the same pattern!
Size: Steel King 15Pcs 10.4"×7"×15.4"
It’s been 10 months, so I feel like I can finally give a decent opinion on this knife set. First of all, I really appreciate how sharp they are out of the box. The set of different blade shapes suits my needs quite well, with the exception of the bread knife, which I swapped in the block for Brodark’s deboning knife. I also added their breaking butcher knife, cleaver, and brisket slicer to my collection, all which match the handle style for this set. (I really liked that I could get the same pattern for some additional blades to expand my kitchen set without getting a different pattern.) The knives should never go through the dishwasher - I tested with one of the steak knives and water spots rusted lightly. I was able to buff the stains out, but the “high carbon stainless steel” is definitely as described. When used normally I do soap and water cleanup, dry, then back in the block without issues. I have honed the chef and slicing knives so they glide through food more easily, but they retain their edges well enough I haven’t needed to repeat the process in normal use. The block is quite heavy and very durable, but still has a rather compact space use as it stands pretty close to vertical. I have mine pulled forward on the counter as our cabinets are rather low, and there is no hint of instability when drawing or resheathing blades. The finish is quite nice, and no need for touchups or worry about the blades wearing in the slots like softer wood blocks can have happen. All the blades fit well in their respective slots. You do need to grip the handles by the ends to draw some of the blades as there are a lot of tools in close proximity, and my fingers and hands are large. I got my set last Black Friday. With the prices and discounts that keep popping up, you could still get a pretty good price most of the year. If you want the option for additional knives of similar handle pattern, do a quick Amazon search for ‘Brodark knife’ and check their options. There have been a lot of good spot sales lately!

Very nice knife set.
Size: Steel King 15Pcs 10.4"×7"×15.4", Size: Steel King 15Pcs 10.4"×7"×15.4"
Got these as a Christmas present and they are a very nice set of knives. They are very sharp so be careful when taking them out of the little sleeves they come in. The wooden base is surprisingly heavy and does a great job at holding the knives without sliding around. The built in sharpener works good to fine tune the edge with just a gentle pull through the ceramic side. They also come with a lifetime warranty which is nice.
