Electro-Harmonix Knockout Attack Equalizer

It's easy to get a sound out of, readily adjustable (intooitive, in mod-speak) and the manual sheet is fine, a tad more detail would be welcome but maybe there's nothing more to say. Since there's so many different settings possible for a given guitar, let alone all your guitars, noting settings would be easier if there were notches/increments printed onto the surface around the control nobs. The switch makes a robust kachunk when, uh, switched but I guess for many players that would be laughably inaudible.

It sounds great, works great and does more than it's touted for. It morphs a guitar subtly or drastically with a broad palette of shades- humbucker to single coil etc, but it can also breath body and sizzle into lackluster or snarky pickups or a thin amplifier. It's plenty quiet and it did what I wanted it to do to my sound and more. As advertised, it's more than a specialty EQ. It's a tone, sparkle and clean bass-boost machine. Excellent and good value!

Seems quite sturdy, I won't carry a backup.

Don't know.

I wanted something to tame the mid range snark of the stock pickups on my new Grestch 5120 till the TV Jones pickups arrive, which it has done admirably. It also works to somewhat acousitfy a electric guitar amp by scooping the mids and boosting cleanly the 85 and 6.5K bass and highs. I've been a fulltimer for 35 years, piano and guitar, mostly solo. I recommend it highly- it IS an EQ really, I think, and as such you can also use just to fine tune your sound when a room gets more full of people and you want a tad more treble cuz the bodies are soaking up the top end...and so on. Yo, I'd replace it with same.

It's very easy for me to dial in a tone that I like.

I'm using a PRS SE Singlecut guitar with 70s Fender Pro Reverb amplifier. Sometimes this guitar is not "twangy" enough. With the Knockout I can play country and funk licks and the tone sounds very authentic. Okay, it doesn't make the guitar sound exactly like a strat or a tele but it's close and very useable. For example, the guitar's tone on the intro/solos to Dwith Yoakam's "Guitars and Cadillacs" and/or Johnny Cash's "Folsom Prison Blues" sounds pretty righteous to me.

It's worked every time so far.

I play in a blues band most of the time and sometimes play with a bar cover band that plays some country tunes. The Knockout helps me through gigs with each band.

Three Knobs- Low, Dry, High

What I was looking for and more. On my Carvin with light strings Bolt guitar with Wilkinson Bar. The songs "Big Log" by Robert Plant metalic jangling out of phase sound (bridge/middle position) with the Boss Super Shift P5 using the detune mode I nailed it. The song "Your Secret Safe with Me" by Michael Franks guitar sound or song "Going Back Home" by Stephen Stills with Eric Clapton on 2nd guitar (1970)album that out of phase quack sound but a more metallic jangling sound. Plus other different sounds you can't get from an equalizer.

I guess it'll last but solid.

I'd buy another I found what I was looking for for that type of sound. The pedal is worth turning it's knobs for other interesting sounds. The pedal has two different filters not found - I understand - in an equalizer. I have an old 10-Band MXR EQ I came close to the sound but no metallic jangle. The pedal is worth it to look for other tones by itself or other pedals in conjunction if your are not in a recording studio.
