Open Box Ampeg PF-500 Portaflex 500W Bass Amp Head Level 1

The Ampeg PF-500 Portaflex 500W Bass Amp Head is the solution for bass players demanding massive power and flexibility in an ultra-compact package. Delivering a staggering 500W of pure Ampeg tone, the PF-500 pairs perfectly with Ampeg's PF Series cabinets for a vintage-styled rig that is astonishingly portable.

Shape Your Sound With a Full Suite of Tone Controls

An extensive array of tone-shaping options provides complete control over your tone. Standard bass, mid and treble controls are augmented by a 5-position midrange selector for honing in on the perfect mid frequency. Ultra hi and lo boosts add further on-the-fly tone tweaking potential, while a built-in compressor keeps levels tight and punchy.

Direct Out and Effects Loop Offer Ultimate Flexibility

Whether recording in the studio or performing live, the PF-500 stands ready to interface with the outside world. A balanced direct out with pre/post-EQ selector, -40dB pad and ground lift provide a pristine signal path, while an effects loop with mix control and footswitchable operation—using the optional Ampeg AFP2 footswitch— grant access to time-based effects without compromising your core tone.

Roadworthy and Ready to Rock Wherever You Go

The PF-500 is ideal for bassists constantly on the go. Pair it with a PF Series cabinet to create a vintage-flavored rig that is astonishingly compact and portable. The rugged steel chassis and durable knobs are built to withstand the rigors of the road and provide years of dependable service. When it's time to rock, simply grab the carry handle and go—your massive tone will be right by your side.

Vintage Styling Meets Modern Versatility

While the PF-500 and PF Series cabs are modeled after Ampeg's iconic Portaflex designs of the 1960s, under the hood lives an advanced 21st-century amplifier delivering power, features and performance like never before. With the PF-500, you can achieve any tone—from vintage thump to modern grind—in a package infused with classic Ampeg style. The future of bass amplification has arrived.
