Hi Although mostly an orchestral player I do play a little jazz and also with a a tango group playing predominantly Piazzolla. This group has started to get a few gigs where we need to be amplified. My current set up is very old and although just about acceptable for the couple of jazz gigs I do a year, is horrible when used to amplfy arco. I do not earn much money with the group so do not want to buy anything too expensive and I also suffer a lot with back trouble and so weight is an issue. My conclusion after much investigation is to buy the K&K Golden Trinity Bass Max Microphone & Pickup System in conjunction with either Phil Jones briefcase or flightcase. Can anyone offer me any advice on which option would be best or if another set up completely would make more sense?
