Amptweaker Big Rock Pro, in perfect condition. This unit has been exceptionally well taken care of and works exactly as it should — no issues, no wear, no scratches. It’s as close to “like new” as a used pedal can get. The build quality is everything you’d expect from Amptweaker: rugged, heavy-duty construction, top-tier components, and that solid, reliable feel that makes these pedals stand out. This is not a lightweight plastic stompbox — it’s built to last a lifetime on any pedalboard. What really sets the Big Rock Pro apart is its huge amount of configurability. Beyond its killer tone, the pedal offers: Dual effects loops with pre/post routing options Multiple inputs/outputs for flexible integration into any setup Internal switches to fine-tune EQ behavior, gain structure, and overall response Footswitchable boost and extensive tone shaping controls A design that works equally well in front of an amp or into a power amp/effects return If you want a high-gain rock/metal preamp with deep customization and professional-grade engineering, this is it.
