The Tone City Bad Horse is a light to mid gain analog overdrive which is nice on its own but really shines in combination with an already overdriven amplifier. That is why the Gain knob is designed to really open up north of 12 O'Clock. The pedal is based on the infamous Klon Centaur pedal and while it does not sound like a Klon, it is by itself a sweet mini pedal effect at a killer price. We like how it behaves with single coils the most, but thanks to a pretty wide eq range, the Tone City Bad Horse works with pretty much any pickup type. As with all Tone City mini pedals, the Bad Horse does not take batteries.
