Ampeg PF500 | 500 Watt Bass Amp Head

Ampeg’s Portaflex PF-500 bass head delivers a staggering 500W of power in an ultra-compact design providing pure Ampeg tone in an extremely portable package. The PF-500 harnesses the performance of Ampeg’s highly-researched MOSFET preamp, setting a new standard for solid-state tone.  Tonal control is no problem with the 5-position midrange control and classic ultra hi/lo boosts while features like the direct out with ground lift and pad are perfect for the gigging bassist. There’s even onboard compression for a tighter, cleaner tone at high volumes. Pair it with our PF-115HE or PF-210HE flip-top cabinets for the vintage styling and portability of Ampeg’s iconic Portaflex originals.
