Nowadays, bass players can get beefy sound without back-breaking weight. Along with the birth of the transistor and neodymium speakers, the development of reliable Class D power amps and super-light switchmode power supplies have been the biggest advancements in bass amp technology in decades. The PF-800 offers classic Ampeg features such as extensive EQ, Hi/Lo frequency boosts, flexible I/O, and most important, 800 watts of legendary Ampeg tone—all while weighing less than 12 pounds.

Considered the little brother of the PF-800, the 500-watt PF-500 sports the same good looks, attitude, features, and connectivity of its larger sibling—just in a smaller package. It offers extensive EQ, Hi/Lo frequency boosts, an onboard compressor, flexible I/O, and legendary Ampeg tone, while weighing only 11 pounds.

Looking for the ultimate combination of portability and punch? Don’t let the size of the PF-350 fool you. It may be the smallest amp in the series, but the 350-watt PF-350 delivers the same looks, attitude, and legendary Ampeg tone as our PF-800 and PF-500 amplifiers. Offering extensive EQ and flexible I/O, the ultra-portable PF-350 weighs less than eight pounds.

The PF-50T is the latest iteration of the design concept that began with the legendary fliptop: a low-wattage all-tube head that delivers sweet and musical tone in the studio and at low-volume gigs. It offers the harmonically rich timbre that only tubes can deliver and its feature-set has the essentials for getting pro-level sound, like a transformer-balanced DI, flexible EQ, and user-adjustable bias control. Pair it with the PF-112HLF for the ultimate compact bass rig.

The 20-watt PF-20T is the ideal all-tube bass amp for low-volume gigs and recording. Like the larger PF-50T, it features flexible EQ, a user-adjustable Bias control, and a transformer-balanced DI. Pair it with the PF-112HLF cab to create a super-compact all-tube bass rig, or use it as an over-qualified tube DI. No matter what you do, you’ll be glad the PF-20T is your tone ally.
