http://www.antelopefx.com Morning Dew Eq pedal. A great little box to keep in your bag for gigs where you don't get to use your own amp. Simple to use, and very versatile. Tweak any amp to your tone, and rock your own ass off.
FROM THEIR SITE:
What's that you say? Just what you've been looking for? Well, we'd like to think so. The Morning Dew, with three simple controls (Bass, Middle, Treble), hosts a plethora of tonal options to squeeze just the right tones out of all your guitars, pedals and amps. But that's not all, friends, and here's where it gets a little confusing: when the Morning Dew is off (that is to say, when the equalizer portion (LED) is off), a stand-alone high-fidelity op-amp based buffer kicks into action. Don't worry, when the equalizer porition is on it buffers your signal in the same manner. This buffering action is not to be confused with cheap buffered bypasses, this one takes your wimpy high impedance guitar signal and turns it into an active low impedance one that keeps your high and low end intact through all your effects and cable runs. Forget tone sucking... this, uh, blows your tone! What?! You don't want a buffered signal? Good thing the Dew has a first-of-its-kind switchable bypass.
