I don't know what to say. This does exactly what it says it does, and does it very well.
The jacks and switch feel super sturdy. The big knob is super smooth and clean - I hope it remains this clean for years.
If I could request one more feature, it would be a trim pot to match dry/wet levels: Even though that would only be useful when connecting units that tend to screw up gain staging, I do have a couple of such alas.
