Electro Harmonix Knockout

Effect pedal for electric guitarAn innovative effect pedal from the venerable old Electro Harmonix Soundsmith. The knockout makes angular single coil sounds out of thick humbuckers - to explain it roughly. This is done with genuinely selected bass and treble frequencies that are mixed with the original signal. Edge without end - but also when the bass range is emphasised, there is no mulching. Instead, it produces a very contoured, crisp bass area. Uncomplicated, you can improve your sound or simply create a completely different sound variant from your favorite guitar.

Don't like this pedal at all

Jonathan G. 504, 11.01.2016
I had great expectations of this pedal, but alas it did not live up to the description. Just doesn't enhance the guitar tone at all, makes it much worse no matter what setting is used. Big thumbs down from me.

Alright!

This box is probably a 3-band equalizer whose bass and treble filters in the usable spectrum are so far apart that you simply use the original sound of the guitar as the middle signal ("Dry"). The bass filter is according to the accompanying sheet at 85 Hz, the height filter at 6500 Hz. This is completely unusual for guitar - and so is the effect: crystal clear ringing, powerful bass. The "Low" control boosts the low basses of the lowest notes to 12 o'clock, only with further turning up the higher guitar tones, thus also the A and D strings are highlighted.
The result is a totally hollowed out sound rich in overtones - just the kind of change you'd expect from a humbucker splitting plus a lot more high frequencies than you've ever heard from your instrument. That does not make a Strat from the Gibson, but the function to awaken these overtones, works well. I have been looking for something like this for a long time.

Direct comparison with Boss GE-7: The knockout is much clearer, easier to use and does not rustle (!), Here seems to take place other than normal height rules.
Direct comparison with BBE Sonic Stomp: Both clarify the sound considerably. The BBE is universally applicable, the knockout rather an effect, but with incomparable clarity.
Direct comparison with Fender Stratocaster: The Strat sounds dull and centered against the knockout. Here you have overcompensated: It sounds stratiger than the Strat itself. So gently use the effect - the 12 o'clock position of the height control is also here a good start.
Effect on my Gibson ES-335: Only moderately, since the guitar itself provides so few high frequencies that there is hardly anything hochzufiltern. Maybe use a "normal" EQ.
Effect with modern humbucker guitar with splitable pickups (Carvin FG-1): Grandios, suddenly everything goes from thick jazz solo to the snappiest Telecaster sound. Downstream effects like Chorus and Echo get concentrates and sound like never before.

In the minus: name absurd, optics matter of taste. A master volume would have been nice. Case in my opinion unnecessarily large, very loud pedal. Downstream of an overdrive or a distorting preamp you get scary chainsaws, so better to use at the beginning of the effect chain.

Conclusion: Purposefully used immediately indispensable.
