This isn't an EQ pedal. It's insulting to compare it to something so simplistic. This is a tone shaping pedal. You can use this little wonder to make any guitar sound similar to almost any other guitar. Freaking amazing! If you're a tone freak like me, buy this pedal and start tweaking!

I have this and I am returning it. It sounds amazing, but it's too noisy to be used with a clean set up. I used it with and without a Boss Compressor and it had the perfect country snappy tone, but again, the noise ruined it for me

    Comments about Electro-Harmonix XO Knockout Attack Equalizer Guitar Effects Pedal:

    Really surprised this pedal is not more popular among guitar players. I found the EHX Knockout to be a great tool for sculpting your basic tone at the beginning of my signal chain. I love both Les Pauls and Stratocasters but could never find a tool to help get that "in between" sound of both guitars. The Knockout comes the closest to achieving that goal. It definitely removes much of the muddiness inherent in humbucker pickups while adding some of the sparkle found in single coils. This is a subtle pedal and if you max out any of the controls it sounds bad. If, however, you spend a little time to dial in the right mix of low-pass, dry, and high-pass filters you will be pleasantly rewarded. If you want to add some sparkle to your Les Paul style guitar I would recommend you give it a try.

    Comments about Electro-Harmonix XO Knockout Attack Equalizer Guitar Effects Pedal:

    Well first of all. Got it because I saw it in a music store and it was [$]. I tested it out at the store but didnt heard it as good as when I used mi rig. Got it home a week later and started playing with it when I went to mi church on Monday night for prair service. It just blew me away how it reacted to mi 6 string Ibanez RG. The depth of the sound coming out of my amp was exactly what I been looking for.

    Provides versatility of sound

    Comments about Electro-Harmonix XO Knockout Attack Equalizer Guitar Effects Pedal:

    I use this pedal in a variety of ways, but mostly to make an inexpensive Dean Boca electric 12-String sound more like a Rickenbacker 12. It's very easy to use, and lets you adjust your sound with high-pass and low-pass filters. Electro Harmonix claims the pedal can change your sound from "Gibson to Strat to Telecaster, with innumerable shades in between." I've found this to be true. With the right tweaking, you can also get a bit of the Rickenbacker sound. Of course, nothing can replace the original sound, but this comes very close. This pedal is an inexpensive solution for expanding the tonal range of your guitar.

    There's no going back...

    By GuyFromTC

    Comments about Electro-Harmonix XO Knockout Attack Equalizer Guitar Effects Pedal:

    I've messed around with all kinds of pedals, trying to find that "right" tone... but still never quite got it. The EH Knockout is the PERFECT tone pedal! This one small, rugged (Made in the USA!) pedal replaced three others on my board. I gave the Knockout 5 stars for features because it has everything you need in three simple knobs - no wasted space. I wouldn't have believed what this pedal can do if I didn't try it myself. Do yourself a favor - buy this pedal!My American Strat sounded pretty good... then I ran it through my Knockout pedal and it came to life! When I switch the pedal off now, it sounds all wimpy and gutless.

    I have been using it for quite some time and as many have stated at first I was a little disappointed BUT after tweaking and playing with it a ton I realized this pedal is freaking amazing and can really change your tone, if your looking for a different kind of sound to add in with your other effects or just need some more... punch as it were, buy this pedal ;)

    A Must

    By Lounge King

    from Europe

    Comments about Electro-Harmonix XO Knockout Attack Equalizer Guitar Effects Pedal:

    Swell desert island pedal-it does what they say it does just great. Here's my angle on it- it also works fab on an acoustic guitar with pickup going into an electric guitar amp (if you don't have an acoustic guitar amp). I tried it on my acoustic running into a Vox DA10 and it sounds wonderful. An acoustic guitar into a electric git amp otherwise sounds pretty honky and mid-rangy and unlovely but this pedal changes all that. Highly recommended for all sorts of applications. I bought a second one.

    A Knockout indeed!

    By Dwindhym

    from Shreveport, LA

    Comments about Electro-Harmonix XO Knockout Attack Equalizer Guitar Effects Pedal:

    The Electro-Harmonix Knockout Pedal is seriously one of the most convenient pedals I've ever used! I'm not sure how to explain it...but it's the perfect secret to getting that perfect tone you have in your head! I've spent so much time with equalizers and boosters trying to get the right sounds out of my strat...but with this thing I sat down and dialed in a mighty Les Paul metal tone in moments! Some may find fault with the simple controls, but I think it only adds to the convenience! You don't have to sit for three hours playing with knobs and sliders. You just turn and go. I dig it.

    A Little Heavyweight Contender

    By Anonymous

    from Undisclosed

    Comments about Electro-Harmonix XO Knockout Attack Equalizer Guitar Effects Pedal:

    I own a Epiphone Valve Junior head and Cabinet so I needed a little control over my eq. I purchased the Electro-Harmonix Knockout pedal, and it gave it just the sparkle, edge and low end punch without being overly harsh like so many EQ's tend to do. Like all EQ's you need to find a sound you like. I especially like the middle knob label 'Dry'. This knob has special filters so you can tweek your mid's and take out the upper mid harshness out of a lot of humbuckers. Then you can tweek it the other way and beef up your skinny coils, (I mean single coils:) Over all I rate it a 4.5. Good sound and good value for the money.
