The Hermida Audio Zendrive is one of the first Dumble-style pedals and it’s still very well regarded. The compressed-but-not-too-squashed tone of a real Dumble is there, as well as the thick overdrive sounds. The company recently released a V2, which features high voltage FET technology that clones the Tung-Sol 12AX7 response.
Works well with both humbuckers and single-coils and can really make a Strat sing. The II version is smoother and a bit less gritty.
