Possibly the most-recorded bass amp brand in history, Ampeg has a long lineage of legendary amps and have cultivated an incredible craft along the way.
A direct descendant of the manufacturer’s legendary B-15, the Ampeg PF-350 Portaflex Bass Amp Head delivers vintage vibe with modern features and a high-powered design that makes them hard to resist.
Give into Temptation
With vintage cool working in combination with contemporary features, the Ampeg PF-350 gives the best of classic and modern. Super lightweight, weighing in at a meagre 3.6 kg, the amp head is compact, and working with the fliptop design of Ampeg’s cabinets, they are amazingly easy to transport. For those who are unaware of fliptop, this feature keeps the amp head secured to the top of the cabinet, allowing the top, with the amp head attached, to be turned upside down and placed inside the cabinet.
Small and Powerful
Lightweight and ultra-compact, the Ampeg PF-350 is deceptively powerful. Although it has the lowest power rating of the Portaflex Series, this solid-state amp head throws out a seriously hefty 350-watts of class-D power rms into 4 ohms, making it one of the most lightweight heavyweights you’ll find.
The Ampeg PF-350 Portaflex Bass Amp Head is suitably stuffed with bass-friendly controls, with Gain, 3-band EQ, volume, pad, limiter controls, and -15dB input pad controls.
The incredible power of the Ampeg PF-350 Portaflex Bass Amp Head can be harnessed in a number of ways. Two speaker outputs give options to connect to a speaker cabinet with a rated power output of 350-watts rms into 4 ohms, or 250-watts into 8 ohms.
There is also a balanced XLR line output available for connecting to an external mixer or a recorder, so you don’t have to mic up the speaker cabinet and output is not affected by the unit’s volume control. The Ampeg Portaflex PF-350 also has an effects loop for sending your signal through an external effects processor and receiving the processed signal.
A 1/8” TRS stereo input and 1/8” TRS stereo output, make excellent practice aids. Hook up your audio player into the input and you can play along with your favourite tracks, listening through your headphones plugged into the output.
