  • offer for a lot of people with very different needs.

  • Marc van de Graaf –
    I love this amp! The Palmer FAT50 guitar amp delivers exactly what the specs promise. And more! This outstanding piece of technology "Made in Germany" exceeds all expectations. An amplifier, which covers all
  • my musical styles from Country, Country Rock and Southern Rock to Blues, and Blues Rock.
  • Guitarrista magazine (Spain)
    A high quality combo, perfect for those who love classic distortion sounds.
  • Guitar Magazin (Germany)
    The FAT50 outstrips expectations with great dynamics and direct responsiveness, making it possible to shape many a sound. This feel-good amp gets rid of the question of the right guitar, since it works equally well
  • with single coils and Humbuckers, dressing them up in an appropriate outfit. Stylistically versatile and equipped with great extras, the FAT50 may quickly become the love of your life.
  • Magman
    absolute hot amp and yet not even soooo expensive. A really good recommendation!
  • Samuli Federley
    As a studio and live musician, high reliability is tantamount. In my style, I often use 8-string guitars that are known to have their own unique requirements. Both the clean and distorted sounds need clear definition. The
  • amp must reflect the deep tones clearly without compromise - which is especially important in fast passages. The FAT50 meets all these requirements with flying colours, I couldn't be more pleased! My first choice in the studio and on stage.
  • Sergio S.
    The amp had just come out and after (...) a direct comparison with five other (...) I have bought this incredibly insane amp of a brand previously unknown to me, (...). (I think I was one of the first in Germany - which made me a
  • little nervous at that time). The amp is still the best one I know, because it is very flexible and always a pleasure to play.
