The EP is a well made little box that fattens up the 'already really nice sounding' signal from the single coils in my strat-- giving my other effects some new-found juice, and allowing me some headroom to use the guitar's volume knob to dial in the sound I want without losing presence at '7'.Having tried a couple of other boost/pre pedals and I appreciate that the EP doesn't (in my rig at least) add hum or hiss -- and doesn't (as I'm using it) add a 'drive' characteristic to the

Liked the sound of it better than the full size spark too which was blatty and wonky

I found that using it as a gain input to the distortion pedal results in some very warm sweet sounding crunch :-) very nice.

Low noise, great sound

Get a bright drive or a very dark vintage sound.

One is inundated with bold claims of "killer tone" and "sounds just like your favorite rocker" and furious but ultimately meaningless diatribes about making you a "better player in only minutes."

great sound.

It's not transparent--you definitely hear the effect of the preamp on your tone--but overall it will enhance the sound of your guitar, amp, and the nuances in your playing.

This boost will prob help guys with lower end gear get a better sound, but if you've already got pro quality stuff I don't see too much of an advantage here.

It opens everything up and adds a nice sparkle that lingers warming up your whole sound

Low noise, great sound

This pedal has a great sound, is always on in my pedal board

The EP Booster actually seems to make your fundamental sound better

It's very warm, musical, and slightly compressed sounding, with nothing artificial added

The "EP" refers to "Echoplex", which was a (large) vintage delay unit with the added benefit that a lot of guitarists decided they loved the sound of the effect's preamp engaged irrespective of the delay.
