Ampeg Portaflex PF-50T 50w All Tube Bass Head

Ampeg Portaflex PF-50T 50w All Tube Bass Head


High Fidelity sound in a compact, portable head. The Portaflex PF-50T from Ampeg is a harmonic rich, high headroom All-Tube 50 watt Bass Head. The warm sound of this powerful amplifier conjures vintage Ampeg tonality, in a lightweight and gig ready package. You'll find 12AU7 and 6L6 tubes powering the PF-50T with 12AX7 tubes voicing the preamp section. Running this amp clean, you'll find a pleasing warm low end with high fidelity treble and mid range, and when you push the tubes the Portaflex gives you classic Tube overdrive. The front panel is simplistic yet powerful 3-band, Mid Selector, and Ultra Hi/Lo Boosts make EQ sculpting easy. To make this amp even more versatile, no speaker load is required for silent recording or to use the head as a dedicated tube DI.

Pair it with the PF-112HLF for the ultimate compact all-tube bass rig.
