Here's what Rockett say about their Lenny:
Lenny was a happy accident. We set out to design a recreation of the legendary Dumble Steel String Singer but thought…who needs a loud, clean amp sound in a pedal? The guy that made the Steel String Singer come alive was none other than SRV. With that said, Lenny was born! It was our intention to create a Steel String Singer being pushed to create color, texture and feel versus just loud and clean. Simply put, this is a very musical boost that colors your tone considerably, in an inspiring way…kind of like a Neve console. There is a definite mid character, but boy does it cut through a mix!
