PF-350 / PF-500 Bass Guitar Amplifier
Introduction
Portable. Powerful. Sexy. Ampeg designed and built the original Portaflex Series over 50
years ago. Congratulations are in order – for today, in your hands, is the new-and-improved
Portaflex!
Featuring Class-D power and knobs galore, these beasts pack a mean punch with a wide
variety of tones at your disposal. Also, the switching power supply keeps the weight low,
without sacrificing power output or our legendary sound quality.
Don’t stop now! Your Portaflex amplifier is an ideal companion to the Ampeg PF-115HE or
Ampeg PF-210HE cabinet, available separately.
Like all Ampeg products, your Portaflex amplifier is designed by musicians and built using
only the best of components. Each amplifier is tested to confirm that it meets our
specifications, and we believe that this amplifier is the absolute best that it can be.
In order to get the most out of your new amplifier, please read this manual before you begin
playing.
And thank you for choosing Ampeg.
