I am delighted with this purchase. Double compressor and boost pedal. It does the job perfectly. Easy to adjust, with subtle but well-present effects. You can feel a real difference. You can chain the two effects either in parallel or one after the other (in the order you want), and that's a real plus. It greatly improves my sound. The value for money is excellent. It looks solid, metal casing with a nice pearly white color for aesthetics. I would buy it again without hesitation.
