Park were always a good amp! SMART move too adding the PPI Master volume. Gets you a closer to fully cranked sound without high vol as the Phase Inverter gets pushed properly. Most master vols are PRE PI!
Sounds great. Why not swap the fuse location with the master volume? Seems weird. I'd rather not see the fuse at the front of my amp, but I guess that's just me. Sounds great, either way.
