Union Tube's Snap, Crackle and POP range are based on their first Tone Druid overdrive pedal. The difference is they've introduced a treble booster knob, great for lead playing or more versatility.
The POP stompbox has the dynamic range and clarity of the Tone Druid, but pushes the boundaries further. The treble booster replaces the MORE dial, so it's less of a boost and more EQ for your gain. Its grittiness has a classic 60's feel of scooped bass.
Union Tube & Transistor
Union Tube & Transistor are a small company based in East Vancouver that make high-end, boutique pedals with rich tones. The POP maintains the company's creative direction in making top quality, honest-sounding pedals.
Here's what Union Tube & Transistor say about the Pop:
The POP takes the concept behind the Tone Druid but replaces the MORE section of the circuit with a sharp treble booster, allowing treble booster grit that interacts with the analog 12ax7 simulation. Think of sharp Beatles stabs.
