Electro-Harmonix Knockout

This is indeed one the odder effects in my bag. It is considered to be an equalizer filter pedal. It uses analog high and low filters to combine the newly tailored sound with the original one. While it is called an attack equalizer it certainly effects the entire sound. It utilizes three control knobs, low, dry, and high to set the two filters and mix the wet and dry signals. There is a quarter inch input jack and a quarter inch output jack and can be powered from a nine volt battery or an AC adapter.

UTILIZATION

In my opinion the manual included is useful and deceptive at the same time. Since EH bills this as an attack equalizer that will fatten a strat like a paul or thin a paul like a strat it leaves a lot to be desired. The unit is very easy to use and can either be placed in your effects chain the same as an equalizer or in the effects loop of the amp. The unit seems to do very little in front of an amp however in the effects loop it has an insane amout of shaping power. Simply set the low and high filters and blend with your original signal.

SOUND QUALITY

I prefer to use this in the effects loop with a guitar. It can be used with a bass however but I rarely find myself using it with bass. As I stated it seems to have little effect on the signal when used in front of the amp. It is a true bypass pedal so it will not color your sound when it is disengaged. When it is in the effects loop however this becomes a beast. It can be used to add a high end edge, add low end punch, or my favorite add both high and low and blend out a good amount of the dry signal. By nature it seems to have a scooped mid and can act like a contour control on roids. It can add a metal edge to an amp that usually does not generate tones in that vibe. Although it does sound there is something inorganic about it and it seems to become apparant after time.

OVERALL OPINION

There really are not many pedals to compair this to and it is a neat novelty to own. It is fun but it always finds its way out of service. Maybe if I had less gear options in the amp and guitar departments it would see more service but I always seem to have fun with it untill i decide my tone is better without it in general. It is not a costly pedal but it also sees limited action so value is a wash and I belive it sticks around more as a novelty then anything else. I think it would have been a better unit if maybe the filters were frequency assignable but meh it was inexpensive so what did I expect. It is well built but if something would happen to it I do not believe I would be desiring a replacement.

This is a pretty simple EQ pedal. It has 3 filters, Low, Dry, and High. You can boost or cut any of them however you want. This pedal is supposed to be able to make humbuckers shine like single coils and vice versa. From what I understand it's very simple analog technology that has been around since the 60's. It has an input, output, and a place to plug in a 9V adapter. Fairly simple, and easy to use.

I gave it an 3 because it doesn't do what its supposed to do, but and it doesn't eat the tone when it's off.

UTILIZATION

It is very easy to use. Each of the filters is very easy to understand. Dry means the original unaffected signal. They could have done more but there's not really anything thats confusing so I gave it an 6.

SOUND QUALITY

Here's where the problems lie. The sound. This is the crunchiest pedal ever made. On a guitar its almost useless. It either makes a distorted guitar so crunchy it makes you nauseous, or it makes a clean guitar so crunchy it makes you nauseous. It sounds cool in the first 5 minutes but after that you start to get very annoyed and you end up tossing it in a corner. It will overdrive your tube amp in a second and no matter how much I tweaked everything I couldn't get a real sounding or useful guitar tone. I read that it was supposed to make humbuckers sound like single coils and I thought "Hey, this sounds like a great pedal." I was wrong. It does not do anything like that.

I tried it on my friends Rickenbacker 4003 through a Fender Bassman and I did get a pretty cool almost wooden tone but it gets old fast. It's almost like Boosty Collins, but due to the limits of this pedal you can't quite get there.

I gave this pedal a 2 because it was thoroughly disappointing.

OVERALL OPINION

I am not happy with this pedal. It does not really have a useful sound in it no matter what you use it with. I read about it on musiciansfriend.com and thought it would allow me to get brighter tones but it did not deliver. While I should've known for 60 bucks that it would probably be of poor quality, I expected more from Electro-Harmonix.

I recommend that people avoid this pedal. It's a waste of money and they are worth nothing if you trade them in.

I give it a 2 overall.

it is a double filter (1passe there and a high-pass) + volume input
by pedal

UTILIZATION

simple configuration with a volume over a dry filter is simple and effective

SOUND QUALITY

This pedal allows you to sculpt the sound of your instrument very finely and very simple, if you spend a little time it really improves the sound quality of the instrument ... I tested it with a Jazzbass a Squier Bass VI and Jagmaster a jetbaritone Gretsch, a Fender telecaster bass. I was able to correct minor flaws bothered me for each instrument, provide some clarity in addition to those equipped with humbucker ... my Jagmaster has transcended found I could get out of it near its a telecaster ... I got out very dub sounds of my Jazzbass

OVERALL OPINION

an excellent price-quality ratio, which would be great is the ability to adapt frequency filters for even more flexibility ...

Equalizer electro-harmonix pedal format.
3 pots, a LED, 9 Volt power supply, classic, nothing abnormal.

UTILIZATION

The manual was not very important, but as often Ches EHX, very simple settings. The low increases the bass, treble increases the high, dry and increase the input volume.

SOUND QUALITY

This is in sound it gets interesting. I bought this pedal as a bass player. At the time, I was playing on a low-end amp, and I tested this pedal on an amp low-end store.

I wanted to test this pedal just to see, and I left with. This pedal provides more roundness and warmth to the sound. I used it almost constantly engaged, and I avoided cold and the sound of my amp. It was amazing, this pedal change the sound of my amp, but not necessarily add to the attack (unlike the name).

I tested it on paul epiphone and Squier Telecaster and it's true we can Avoie the sound of another with the effect. Finally, on a les paul, the sound resembles a Strat, but it stops there. To see.

In any case I prefer it as a bass player.

OVERALL OPINION

I bought it in early last year, but I have more utility too, because I opted for a preamp tube amp. I think this pedal is very unique and original, it is perfect to enhance the sound of an amp cold. It is useless on a good amp.
For a guitarist, I would say why not, but my try with your gear
