Wow.

chr1stoph 20.04.2026

Ich bin wahrscheinlich einer der ersten, die dieses Teil nach Veröffentlichung zu Hause haben, und ich kann es nicht anders sagen: Einschrauben, Akkord spielen, weggeblasen sein.

Ich hatte das Erlebnis schon mit meinem ersten Synergy-Modul, dem SLO II. Und jetzt wieder. Ich hab auch einen Kemper, ich probiere gerne Profiler und Modeler aus, aber diese Art von "wow!" krieg ich einfach nur von echten Amps. Ich hatte nie einen JCM800 zu Hause oder im Proberaum, ich kenne ihn also nur als tausendfach nachgeahmtes Modell und fand das oft schon toll. Aber dieser Kollege hier... wow.
