Ampeg PF-20T overview

  • 1Description

The Portaflex Series PF-20T from Ampeg is an all-tube 20W bass guitar head amplifier that delivers the legendary Ampeg tone in a lightweight design to all bass players around the world, from beginners to professionals. When matched with the optional Ampeg PF-112HLF compact cabinet, the PF-20T creates a fantastic portable tone powerhouse.

The heart of the amplifier contains two 12AX7 preamp tubes, as well as two 6V6 power amp tubes. The font panel offers a standard 1/4" instrument input, a 3-band EQ, and independent gain and volume controls for dialing in just the right amount of distortion and drive.

The rear panel features an XLR preamp output with a post/pre-EQ switch, while an additional transformer-balanced XLR output may be used to feed an external power amplifier, mixing console, interface, or house PA system. The 1/4" speaker output includes a 4/8 Ohm switch allowing for flexibility when using multiple speaker cabinets. Additional features include a power switch and standby switch, which helps preserve the life of your tubes when not playing. The amplifier also offers a bias control and a set of LEDs that allows you to properly bias the power amp when replacing tubes or for changing tones. The PF-20T ships with a standard IEC power cord.
