Ampeg PF-20-T All-Tube 20W Portaflex Head

The sweet, legendary Ampeg tone that players have loved for decades is faithfully reproduced in the all-new, all-tube PF-20T. Similar to its bigger 50W brother, the sleek 20-watt PF-20-T head delivers the same famous, harmonically rich Ampeg tube tone that has made the Portaflex a long-time studio and stage favorite. It's also the first all-tube Ampeg amp in this price range.

The PF-20-T features a redesigned Portaflex profile with the same attachable flip-top format. It offers ample tone control, including 3-band EQ, a 5-position mid switch, and Ultra Hi/Lo boost switches.

A user-adjustable bias adjustment makes tube replacement simple. Preamp and transformer-balanced direct outputs provide maximum versatility for studio or stage use. The amp can also function as a tube DI or for silent recording without a speaker load.

Pair it with the new PF-112HLF ported modular 12” cabinet to enjoy the portability, power, and punch that have been Ampeg trademarks for over half a century.

Why We Like Ampeg Bass Amps

The Ampeg name is synonymous with bass. From the classic Portaflex amps that graced bandstands and recording studios in the early 1960s to the massive SVT heads and cabinets defining arena-caliber touring rigs, Ampeg has always meant great bass amplification. Clean, classic low-end tone is a given. Stage-rattling power and road-defying build quality have only added to its legendary status.

Many excellent bass amp designs have come and gone, but Ampeg amps remain timeless. Nothing has weathered over 60 years of bass amplification like Ampeg. We know it works. That’s why we like it.
