Dear Bass Brothers, I have a Kinal SK5 that I love but I'm considering modifying the preamp circuit. It has a John East MMSR with a Villex PRTB, but I'm not getting the ideal sound for my ears. I'm considering switching it out to the Glockenklang 3-band, the Aguilar OBP-3, or the EBS onboard... Finding out info on the Glock and Aguilar is easy, but no one seems to know much about the EBS. If anyone has tried one, I'd love to know! Please give me your thoughts and comments on the comparisons between the East MMSR, EBS, Glock, and Aggie preamps.
