The Bombastortion (Jeff Kollman signature overdrive pedal) designed by Tim Jauernig.

Relisted The Bombastortion is a mid-drive gain pedal with a fast attack and a big low-end attack. It boosts the presence of any guitar running through it adding sustain and a singing drive when put in front of a clean amp. Think big fiery blues and rock and you're i the ballpark.
With a toggle switch on-board to duck or boost the bass according to taste and a 3 band EQ that will morph depending on where the other frequencies are set. Take your time to find the sweet spot (According to the guitar you're play, whether singlecoils or humbuckers) and let that drive scream.
Control knobs:
• Volume
• Gain
• 3 Band EQ - Treble, mid, bass

Here's what T Jauernig Electronics say about the Bombastation
The Bombastortion (Jeff Kollman signature overdrive pedal) designed by Tim Jauernig.

This overdrive pedal is based on my guitar tone with the Bombastic Meatbats. We’ve been tweaking this baby for months and have the tone of the gods in one single channel, true bypass pedal.
If you love the big fat lead tones of say Gary Moore, you will need to look no further.
