Ampeg Portaflex PF-350 Bass Amplifier Head (350 Watts)

With a built-in limiter and 350 watts of power, this nasty little amp head produces quite a powerful punch of sound without lots of high-end distortion.

Ampeg's Portaflex PF350 bass head delivers legendary Ampeg tone in an ultra-compact, highly-portable design that pushes out 350 Watts of power via efficient Class D amplification. The Ampeg PF350 harnesses the performance of Ampeg's highly-researched preamp, setting a standard for solid-state tone. Tools like a true FX loop and balanced direct out and stereo 1/8 inch input and output for home practice provide the flexibility demanded by the modern bassist. There's even a built-in limiter, keeping your bass tone cleaner and tighter at higher volumes without risk of clipping. Pair it with Ampeg's PF-115HLF or PF-210HLF flip-top cabinets for the vintage styling and portability of Ampeg's iconic Portaflex originals.

Powerful, simple, and portable -- this video from Ampeg highlights the features of the Portaflex PF350:

I purchased this head in I believe 2015. I have traveled and used this allover the country. From small groups to various shows. Including a show in Madison Wisc. at the Veterans Memorial Coliseum with over one hundred other musicians and vocalists. I used the PF350 with two vintage B15N cabs and it just rocked hard and loud. It easily cut above trumpets, trombones, euphoniums, and a drummer. Including keyboard and other musicians. But the best part was I did not use the DI output.

Sound
When performing, I use three different basses. A Fender Jazz, Ibanez GSR206SM, and an Pedulla Thunderbuzz. So it's all of the major basses 4,5 and 6 strings both fretted and fretless. I use a Behringer MX400, a mixer, so I do not have to plug and unplug all of the time as the PF350 only has one input. I have a typical Ampeg tone from all of my basses, a nice deep but mellow with just enough treble on top.

Features
The features are not many. So in my opinion, that's what is nice. It's nice and simple to set up, and yet the sound is to die for.

Ease of Use
As far as ease of use. The simpler the better. Especially when you have a lot of setting up to do and you have an orchestra director that's in a hurry.

Quality
Quality is amassing. This bass head is built like a tank. Like I said, I have used this head allover the country and in venues large and small

Value
Value. I read more do not believe you will find a more useful bass amplifier at this price, with ease of use, or as reliable as the PF350.

Manufacturer Support
Since I purchased this new, I have never had to call Ampeg. But I trust that if I ever have to, they will treat me well.

The Wow Factor
The WOW FACTOR is when those that you are performing with, say to you, that they have never heard a bassist with as clear a sound or as loud as your performance. Other musicians have said to me that they can actually feel the performance in their chests. In the practice room, it can shake the floor.

Musical Background:
I have been playing bass for over fifty years and I play semi-professionaly.

Musical Style:
I play fifty and sixty's rock, country, show tunes and adult contemporary or new wave.
