Heavyweight history in a lightweight design.
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. Precise tone controls and gig-friendly input/output options provide ultimate flexibility. Pair it with Ampeg's PF Series flip-top cabinets for the vintage styling and portability of the iconic Portaflex originals.
The tone stack on the PF-500 provides an extensive array of tone controls for shaping your sound. Bass, mid, and treble controls come standard with a 5-position mid switch for finding the perfect midrange level for your sound. Ultra Hi/Lo boosts add even more on-the-fly options, and an onboard compressor keeps your levels in check and your tone punchy and tight.
At the gig or in the studio, the PF-500 is ready for action with a balanced direct out with pre/post-EQ selector, -40dB pad, and ground lift. An effects loop with dedicated mix control is footswitchable with the optional Ampeg AFP2 2-button switch.
