...Just gonna jump in here because I can.
I assume the clean boost is to drive the tube front in the PF50T.
I don't understand the dragster either, or the placement of the limiter. I mean, you do you, bass brother! Of it sounds good then it *is* good. It's just that to me, your rig is arranged in a way that is very different to the way I'd arrange it if I had your pedals... Why use the dragster? I'm pretty sure your pedals are true bypass. Also, why did you choose to put the limiter right after your bass, instead of after the boost? And are you running two Ampeg PF-50Ts? Inquiring minds need to know!
