TESTIMONIALS

Thank you Jens ! for the awesome job that you did on my Jubilee! the amp is way more expressive and musical now , and the low end has heavyweight punch. Thanks again.. Randy

had sent my marshall 2553 short box jubilee to Jens Kruse for some work....he brought it back from the dead and modded it with the additional gain stage. After a few weeks of getting it adjusted to the band.. it's the best amp iv'e ever owned... Great job Jens !

The Marshall Jubilee with the Kruse Gain Stage sounds RIDICULOUS, I can't believe the tone. This amp used to be in storage as a collector's item, now it's my best sounding amp that I'm playing ! This high gain mod not only improves on the original stock tone of this amp, but also adds a natural sounding overdrive that rivals any pedal and yet sounds like it was designed into the original circuity of the amp. I cannot believe how great this amp sounds AND it can still be returned to stock (like I would ever sell it…NOT) if one would like to sell the amp to a collector.
