Demystifying the Boss EH-2 Enhancer (Spectral Analysis)

I thought I'd do a proper analysis of a seemingly misunderstood pedal, as I was unable to find this info anywhere.
Hit me up in the comments if you have any questions!
What's happening is the clean signal is always being passed at unity gain, but signal is also sidechained through a 2nd Order High Pass filter, then mixed into the output. The Trebly, High-Passed signal is envelope controlled in order to, primarily, add brightness (lots of treble) to your attack, then die back down after your attack and not raise the noise floor or introduce hiss.
The Inv side of the Mix knob is blending in 180* out-of-phase treble, which cancels with the clean treble, bringing the overall treble down, but as you crank it counter-clockwise, it overpowers the clean signal and the phase cancellation goes away, and it does more-or-less the same thing as mixing in the non-inverted high-passed signal.
If I understand correctly the clockwise setting is a treble expander? The counterclockwise setting is still hard to understand. Thnx for the explanation
@@pimcramer2569 It's still a treble expander but since the additive signal is out-of-phase, there are cancellation effects and the EQ curve is wonky. The end result is still a brighter signal, but there are some notches in unexpected spot as you turn it.
Once you crank it to fully counterclockwise, its basically the same as fully clockwise, because the out-of-phase signal overpowers your dry signal and the cancellation / notches go away.
@@dagus834 thx, you know your stuff!
More like an all-pass filter
Brilliant video, totally explains why this pedal sounds awesome on my electric piano. I wish more pedal videos had spectrum plots
This is the first pedal in my FX Loop on any amp. My signal chain is pretty long, with 40 different pedals in the . I have a preamp pedalboard with 16 pedals, dedicated to increasing gain and distortion (fuzz, boost, overdrive, distortion, feedback/boost from FZ-5, to BD-2, and all the overdrive, distortion, and metal pedals to end at MZ-2). It adds clarity to the distortion pedals so that they are not so muddy, especially when stacked. Immediately after is an SP-1 Spectrum, which is a single band parametric EQ and acts as a boost into the remaining effects in the FX Loop. I dial in the levels to align with my attack (the red light blinks when I pick, no matter how light). Depending on what other effects are in the signal chain (vintage pedals add some tone suck, even with the proper isolated power supply), I have to tweak it a little to dial in the sweet spot for what I want to get out of everything.
Great analysis! I use one on a jazzmaster with super thick chorus. It really makes the chorus separate from the original signal.
Does nothing? Try it with a Vertex Steel Strings- it will make your teeth ache and your eyes bleed - in a very “treble “ way. I find it amazing with a boss blues driver. They are scarce now, don’t over look them if you are a tone perfectionist.
I have one and my best use for it is after my Waza Metal Zone to kind of take some of the ice pick out of my ear. Very misunderstood pedal. Awesome video man. THANKS!
Lovely!
Try that Metal Zone with left EQ at 12 both and right EQ pot Mid freq 5k and internal pot (middle) all cut off . That will kill that mosquitos freq that hurts soo much!
What kind of settings do you have on the EH-2 for that usage? Thanks!
Currently using this pedal. It's actually very useful! Thanks for the analysis!
hi, I m have one, and for me it s like a buffer with frecuency control, always ON in my pedalboard
Shouldnt use white noise.. need to use pink noise for the correct energy/frequency
You should use pink noise for this kind of full spectrum analysis.
Does anybody try to use this in the loop fx? Before most distortion pedals or preamps will help to cut mudy lows and crushing highs.
What does the third knob do?
so basically its a wacky eq pedal lmao
it’s another of many pedals that guitar players just don’t know how to use properly, so they claim “it doesn’t do anything!”.
What spectral analysis app are you using?
Hello fellow fender pro sonic user!
So what a fukkk it does? It brightens the sound like turning guitar tone knob to 11! Kinda more clarity, transparency.. what’s going on here? It simply shelfboosts highs??Thnx bro ❤
It does exactly that, but dynamically. The harder you play, the brighter it gets. On the flipside, if you inverse it, the harder you play, the darker it gets.
@@leecampbell1763 got It. Cheers beers
I fell asleep while you tried to explain these 3 knobs
wouldn’t an EQ pedal be more useful?
Depends on the application. This isn't the same as an EQ though, it's closer to a dynamic EQ but for the highs only
Mine has no hiss at all but thats because I spent a bit of time, replacing stuff inside with higher quality parts!! lots of Japanese Panasonic capacitors
Yeah he only used white noise as an example so you can see what it's doing to your sound on the frequency chart. It doesn't actually cause hiss
Demystify this shit? Yeah...I hope this helps you!
If you need a spectral analysis to prove that this pedal does something then it probably will not be of any use to most people.
Most people are not sound engineer, dude. Most people ain't exactly smart, neither do they have a very well trained ear.
the most unless pedal ever. doesnt even do anything
This video is literally him showing you what it does Josh
