A transparent amp allows different basses to sound different , instead of running everything through a baked in sound. I went from a GenzBenz Streamliner 900 to a Bergantino Forte. The Benz has a three tube preamp , and does warm and tubey , or you can make it fairly clean however the Forte is a simple clean platform with some serious slam. With the Forte the individual character of different basses comes through much stronger.
Two very different amps and I’ve gone for the Forte for gigs. I also have SWR , GK , and Darkglass amps. The SWR and GK have distinct personality , the Darkglass is a chameleon.
