The Sushi Box FX Wrecking Ball is a pedal-sized version of the Mesa/Boogie Dual Rectifier preamp. It runs 3x 6N21B miniature tubes in place of the 12AX7, allowing it to keep the same tone as the original but at a fraction of the size. If you're looking for real saturated tube distortion but in a small package, this is your best bet. It runs internally at 200V on the tube plates, but all voltage conversion is done internally, allowing it to run on a standard 9V input. It does require about 1200mA of current though (an improvement over v2.3), so please plan your power supply accordingly. I recommend the Visual Sound 1Spot (not affiliated) which can supply plenty of current for this unit.
Like all Sushi Box pedals the Wrecking Ball is hand-made in the USA, and I stand by its quality 100%. If there is ever any issue with the pedal I promise I will make it right.
