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.

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 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.

I actually bought this as a practice amp because of its size, and it works well for that. It doesn't really punch like I thought a 350W amp would. But I'm used to tubes. My 100W tube amp seems to put out more db's than this thing. But it also weighs 50 lbs. The 7 lb PF350 is nice and easy to tote around. Sound is good and clean like all Ampeg things are.

Musical Background:

35 years of bedroom bass playing

Musical Style:

rock, jazz, fusion, alternative.

I expect this head will last with care, I will use this till it dies or explodes from too much use but the on board cooling system
Sound
at first I was wasn't sure I wold want an ampeg just the sound is usually tinny and I just didn't like it now after owning it for a month this thing rocks very punchy and handles the low end better than I anticipated I haven't ran thru my full rig yet but even just one cabinet I'ds enough for this
Features
the features are cool it's pretty basic set up wish it had flashing lights for fun, it needs a gig bag all it's own would add to cool factor
Ease of Use
I plugged in adjusted controls and whammo! I found my sound
Quality
I am so happy this is light I think its 8 ponds but man it's nice after lugging all my stuff to stage it's nice that the head is light
Value

I needed a single 12" bass cabinet & chose the Ampeg Portaflex PF350 for the job; I have since had to sell the bass rig; an upright bass player made me an offer I couldn't refuse. He really liked the sound for his Latin Band.

Musical Background:

I've been playing bass 54 years & have recently started on guitar & keyboards

Musical Style:

Blues, Classic Rock & Originals
