That's really the issue for me. In certain settings I play a fair amount of arco and I am giddy about the sound of the Realist for that. In most straight ahead settings I'm pretty happy too. I play in an original jazz bordering on acoustic fusion group (sax,guitar,piano,bass,drums) and find that I can't cut through when I need to with just the Realist.
I heard a guy with a Bassmax/Trinity combo through a AI. It was ok but I wasn't blown away. What I really start to miss at higher volumes are all the beautiful overtones in the uprights sound.
Any thought about my quiet g string when I use the Underwood?
