My son plays in school. His problem is he has about 5 minutes to get on stage and set up. He currently has Ampeg SVT-450H head, compressor pedal, tuner pedal, and Ampeg SVT-610HLF speakers. There is just not time to set this up. I would like to replace the amp with a rack mount with built in compressor which will not over power the speakers. The Ampeg SVT3pro does not have a compresor and the SVT4pro has too much power. Dad is struggling. Any suggestions?????
