TESTIMONIALS

Herbert sounds so much better with this Tone Mod. I've used it on 3 sessions so far and everybody loves it.

Love this mod on my Herbert MK-I. I'm telling ya, I played with another cat who owns an unmodded Herbert MK-II the other night and he was bummed out after hearing mine. I would have sold my Herbert if it wasn't for the work you put into it

Hi Jens I just wanted to tell you my modded Herbert MK-II is amazing !! I've realized Diezel amps are great but once you do your mods (Variac + Tone Mod) they become incredible. I also want to thank you for your exellent customer service. It's nice when a tech can explain details that you can grasp without feeling talked down to .. thanks again we guitarists are lucky to have you in California !

Thanks to Jens Kruse, this beast not only has bite, but personality to spare. As much as I loved the amps basic brilliance, he brought out much more clarity and dynamics and adjustability with the mods he did to this head. I love putting a little effects through my rig as much as the next guy, instead of adding effects and tweaking the amp to my taste, it starts off in the stratosphere and only goes further into space. Saying I’m pleased with the result would be an understatement !

I'm a Diezel Herbert owner who just had Jens install his "Tone Mod".When I picked up my amp and first heard the difference I was stunned. With the amp at a moderate volume and the mod pot turned on at low to mid levels it gives the amp more breath and richness to my clean channel and more punch and growl to my gain channels. With the mod at full it makes the amp push more air and just unleashes the beast of the amp, something I never thought possible. After hearing what this mod did I'm going to get this kind of mod installed in my Boogie and Marshall as well.
