Electro-Harmonix Percolator

The Percolator is an affordable take on the Interfax HP-1 that offers both raw transistor-driven tones and gated fuzz textures. Premier Guitar gave it a 5 out of 5 rating, praising its creative variations on the original's character and strong value, though noting the fuzz mode lacks the impact of the drive setting.
