Critic Reviews

Ampeg Portaflex PF-20T/PF-50T Heads, PF-112HLF Cab review | MusicRadar

musicradar.com

Ampeg's Portaflex PF-20T and PF-50T heads paired with the PF-112HLF cab deliver classic, warm, and fat tones expected from an all-tube Ampeg setup. Praised for their robust build and light portability, these units shine in recording and solo writing sessions. However, they fall short in power, struggling to compete in full band rehearsals without PA support. The PF-50T's additional features like ultra-hi and ultra-lo boosts offer more tonal versatility for those who prefer heavier sounds. While the cab is light and sturdy, its single handle and lack of a flip-top feature are minor drawbacks. Overall, a great choice for recording, but limited for live full-band use.
