Bubble Burster Overdrive

Have you ever read a product description and thought, “Wow… that’s an awful lot of adjectives.”

So did we.

That’s why we created the Bubble Burster Overdrive. It doesn’t promise to rewrite the laws of physics, channel the ghosts of 1959, or magically convince your pickups they’re something they aren’t.

It just makes your guitar louder and crunchier. Like a respectable overdrive should.

Features

❌ Accurately transforms any guitar pickup into a vintage PAF.

Nope.

❌ Proprietary op amp developed in a secret underground laboratory.

None.

❌ Military-grade quantum analog processing.

Absolutely not.

❌ Contains genuine decommissioned submarine parts.

Nope. Just ordinary electronic components doing ordinary electronic things.

❌ Hand-selected electrons.

The electrons select themselves.

❌ Artificial Intelligence tone engine.

The only intelligence involved is you turning the Gain knob.

❌ Patented Bubble Burst Technology.

No patents. No bubbles. Just solder.

❌ Meticulously recreates every molecular nuance of a mythical pickup.

It’s a PCB.

❌ Contains unobtainium transistors harvested during a full moon.

Mostly resistors.

❌ Employs advanced psychoacoustic harmonic phase inversion synthesis.

We made that up. Sounds impressive, though.

❌ 100% guaranteed to make your guitar sound exactly like your favorite guitarist.

Only if you’re already your favorite guitarist.

❌ NASA-inspired signal path.

The traces were routed by someone wearing socks.

❌ Laboratory-certified mojo.

Our lab consists primarily of coffee mugs.
