Critic Reviews

Portaflex PF-20T Review: I own a few classic Fender bass guitars and build one... | Ampeg | Bass Amplifiers | Reviews @ Ultimate-Guitar.Com

ultimate-guitar.com

The Ampeg Portaflex PF-20T is highly praised for its warm, deep bass tones and versatile sound quality, making it an excellent choice for practice and studio recording. The amp's simple controls and user-adjustable bias offer flexibility and ease of use. However, its 20-watt power output limits its performance to small venues, and it requires proper grounding to avoid hum issues. Despite these limitations, its rich sound and classic Ampeg growl, when paired with suitable bass equipment, make it a standout option for those seeking quality over volume.

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

musicradar.com

The Ampeg Portaflex PF-20T and PF-50T heads, paired with the PF-112HLF cab, bring classic Ampeg warmth and fat tones in a portable package. The gear is praised for its robust build and ease of use, making it ideal for recording and solo sessions. However, the heads lack the power to hold up against loud drummers in live settings without additional support. The PF-50T is particularly favored for its additional features like ultra-hi and ultra-lo boosts, but the single handle on the cab and the absence of a flip-top feature are drawbacks. Overall, a fantastic choice for studio work but limited for full band rehearsals.
