Based on Fortin 33, this clean boost delivers +22db of clean gain boost to drive your dirt channel into a djent metal machine without coloring your tone! Includes an internal charge pump to give you all the extra headroom you need.
The Bunker 33 is based around the Fortin 33 ™, a boost that makes every amp a metal wrecking ball. With its massive build in the charge pump, it provides 22db of extra clean headroom to make sure your guitar signal just hits the amp way harder to unlock extra gain from your amp without coloring its overall tone. Because some amps can’t handle that much gain without getting muddy, there is a fixed high pass to roll of some lower frequency to make sure your guitar tone stays where it has to be in a band situation. Al together gives you the signature boost of Fredrik Thordendal from Meshuggah.
The only thing we left out compared to the original unit is the separate jack that Switches your amps channel when engaging the pedal to avoid making this project way more expensive to build and harder to drill.
It’s anyways fairly big for a boost, and the channel switch from the original is not compatible with all amps. The guys that want features like this usually have a Switcher anyways. Have fun building.
Make sure your electrolytic capacitors are rated for 35v or more!
