The Bad Stone is a seriously cool little box for anyone craving that classic 70s psychedelic swirl. It’s a no-frills recreation of the Phase 90, so don’t expect modern modulation complexity, but it nails that vibe perfectly. A great, budget-friendly option for guitarists looking for a specific, iconic sound.
