Thunder Pup XL

Bigfoot Engineering builds all-analog pedals by hand in England. Their design philosophy eschews EQ controls in favor of meticulously voiced circuits that provide the perfect sweet spot while letting your guitar character shine through.

The Thunder Pup delivers classic British overdrive in two distinct flavors. Big Amp mode captures the Marshall Plexi 4x12 stack sound—Angus Young territory with more gain and powerful low-frequency response. Little Amp mode offers faster attack, cleaner mids, and more air like a vintage Vox AC30 or Marshall Bluesbreaker combo.

Like all Bigfoot pedals, the Thunder Pup has no EQ controls because the voicing has been meticulously crafted. Your guitars character shines through while the circuit adds just the right amount of British grit.

Dynamically responsive to picking and guitar volume, it cleans up beautifully for rhythm work and sings for leads.
