Emma Electronic's description is below. I have found that this pedal really excels with Strat style single coil guitars.

We wanted to make a great ‘classic’ overdrive, that has the best of what's out there, but keeps the body and character of the guitar intact.

We worked really hard on the Emma Stinkbug getting the mids to respond well, and the highs and lows to be right for blues rock and pop. We also chose a circuit that has a particularly nice warmth to it.

The low and high controls gives a great control of the amount of mids in the Emma Stinkbug. Turn them both down, and the mid-range comes out, but without being nasal. Turn them up, and the mids gets slightly scooped, still keeping the sound full and punchy.

The Emma Stinkbug works great for blues, pop and rock. It sings well and has great mid-range response.

Continental USA and PayPal only please. I am adding this info. You must have at least 5 positive feedbacks to purchase my gear. I have unfortunately been getting questions and bids from people outside of the USA and have questionable addresses. Not good!
