Ampeg PF-50T overview

  • 1Description

The Portaflex Series PF-50T from Ampeg is an all-tube 50W 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-50T creates a fantastic portable tone powerhouse.

The heart of the amplifier contains two 12AX7 preamp tubes, as well as one 12AU7 and two 6L6 power amp tubes. The font panel offers a standard 1/4" instrument input and a -15 dB 1/4" instrument input to accommodate active electronics found on many bass guitars. The 3-band EQ offers Low and High frequency controls, while the Mid frequency band offers a 5-position switch to help you dial in the perfect tone. Additionally, the Ultra-Lo boosts 50 Hz by +2 dB and cuts 500 Hz by -10 dB, while the Ultra-Hi boosts 8 kHz by +5 dB for additional tone shaping controls. There are independent gain and volume controls, allowing you to dial 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-50T ships with a standard IEC power cord.
