Description
The Crackle rounds out Union Tube & Transistor’s treble booster trilogy, joining POP and Snap as the third take on the Tone Druid concept. Where the original circuit dedicated its MORE section to a different job, the Crackle swaps that section out for a dedicated treble booster stage—giving you that classic bright, cutting push at the front of your signal chain.
If you’ve chased the Rory Gallagher treble-booster sound before and found it too wild or unpredictable, the Crackle is built to be the more approachable version. It delivers that same upper-register bite and pick-attack sparkle, but with a response that’s easier to dial in and live with across different guitars and amp setups.
Placement-wise, this pedal wants to sit early in your chain—right where a treble booster belongs, ahead of overdrives and fuzzes, so it can shape your amp’s front end and add cut without piling on unwanted low-end mud. Great for players who want a vintage British-rock edge without losing clarity in a busier pedalboard signal path.
