Ampeg's Portaflex PF500 bass head delivers a staggering 500 watts of power in a super-compact design providing pure Ampeg tone in an extremely portable package. The PF500 harnesses the performance of Ampeg's highly-researched MOSFET preamp, setting a standard for solid-state tone. Tonal control on the Ampeg Portaflex PF500 is no problem with the 5-position midrange control and classic 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 the PF-115HLF or PF-210HLF flip-top cabinets for the vintage styling and portability of Ampeg's iconic Portaflex originals.
