I wanted something portable that sounded good with my Mojo 61 organ/rhodes. I run the solid state bass amp on the Left channel and the tube amp on the Right.
Fender Rumble 40 Bass Amp (17 lbs) Upgrades: Eminence Baslite 2010 speaker: smoother deeper bass, smoother mids and highs, and louder! (acts like 100 watts now). Retuned the ports with 2 5/8 inch long port tubes. Glued Acousta-Stuf Polyfill on 3 interior walls. Black knobs, original grill logo.
