Was at a jazz / blues venue last night with a full set by Davide Shorty & The Fresh Prints. Great little band over here from Italy. Bass player was very good. Had a quick chat with him at the end of the night. He mentioned he had started using GR amps (gonna quickly get known as the "gramp", right? ) in place of Markbass and he found them to be really "true" to what he was actually playing. I've not come across them before and he suggested I check them out. A recent review on MusicRadar
