Here is what customers wrote about Kruse Kontrol:
I have taken many amps to Jens. He is, by far, the BEST amp modification technician (modification artist) I have come across in my 33 years of playing guitar. How do I know Jens knows his stuff?A little about me:In the 80’s I was Paul Gilbert’s guitar tech (for a short while) when he was in Racer X. After Musician’s Institute's GIT (because Nirvana killed rock), I joined the US Navy and became an Advanced Electronics Technician, doing micro miniature repair/troubleshooting on all types of high performance multi million dollar military aircraft. To put it mildly I know electronics. I later became a Navy pilot and now I work for the US Gov with real rocket scientists, engineers (of all types) and people who are just plain genius. I can tell you, very few (read only 1 engineer that I have met) knows anything about tube technology and even that one engineer only knows basic tube theory. Tubes (for current day applications) are an obsolete technology limited to audiophiles. For comparison, tube amps are like a dead language that only few people know (think Latin or Aramaic ). Find a guy that knows GUITAR TUBE AMPS, can PLAY, and has an EAR, and you get Jens Kruse! BTW, I have opened up my amps and inspected the work…Jens attention to detail and quality of work would qualify as MILSEC.Tony
Amazing bias mods over my Boogie MKIII and my 2:90 power amp. In my country there is no way to get Mesa tubes for replacement, Bias mod gave me the chance to experiment other tubes and a fear comparison runing them hotter or colder. Really cool and useful for recording different types of song styles.Beside that, Jens Kruse gave me exceptional customer support, promptly answering all questions and mails, while I was modding my amps and afterwards. He worried about my amps' functionality for a long period of time.I'm really satisfied with it, I'd suggest Jens Kruse to any person who wants to tweak his tone.Thanks a lotAdrian Herrera - ARGENTINE
"I have to tell you that I am UBER happy that I sent my amp to you. It is roaring like never before!"
"Hey I just wanted to take a moment to say THANK YOU!!!!!! so much for helping me get my amp fixed. You have to be, by far, one of the best people I have had the pleasure of doing business with. You kept me in the loop during the whole process of fixing my amp and then when I went to pick up the amp you walked me through every aspect of the amp, what was done to fix it and he went through every switch and knob to show me everything was in proper working condition.
