Who/what is Vemuram? And Jan Ray?
No idea, but I saw Matt Schofield pay one of these recently, it having having replaced his trusty (and massive and massively expensive!) Klon Centaur on his pedalboard.
So I bought one, and bloody good it is too. Very, very transparent, light to medium overdrive. Just as fine but completely different to the Zen/Dumkudo Twin, it really sounds like an amp working hard, likes a clean amp input and plenty of headroom, but I bet it sounds great turned down driving a more overdriven amp too.
And very sexy, heavy brass casing, distressed finish. If only the led was yellow or orange – it would match the case so much better!!!
