What kind of tube preamp would that be sir dodjie? thanks
Depende sa taste mo. common to that would be the Marshall JMP-1, ADA MP-1 or if mas galit ka sa pera, go for a mesa Recto preamp, Mesa formula preamp, mesa Triaxis or the cheaper mesa V-twin rack preamp. Also look for the old Mesa Studio preamp which is a Mark IIC design preamp.
Another nice option would be getting a nice speaker emulator alongside your poweramp. Split the channels of your preamp to stereo, one goes to the poweramp (or amp's fx loop in), the other goes to the speaker emulator, then ask the techs in the venue to tap your signal. Palmer makes good cab sims.
