Surprised !!!

I really did not know what to expect from a small 350 watt head but was I surprised. I matched it up with the pf115 cabinet and I was blown away with the deep and punchy sound. Has that great vintage Ampeg tone. Using it with a classic country legends band and it fits right in on stage and for practice. Thinking of adding the pf 210 cabinet later to get the full 350 watts out. I would recommend this to anyone wanting a small package with a ton of sound. Thanks Sweetwater for all the help and support. Your customer service is number one!

I'm a long time professional working in a top touring band and thank Sweetwater for their over the top support in keeping my band rolling. My tech is Ian who works harder than some of our in house techs and roadies. And yes, the portables is a great bass power source from rehearsal room to the stageRegards,Les

Gets the job done...and More!

I was looking for something for small gigs and rehearsals and this head paired with 2 Svt210av speakers fits the bill. Outstanding tone and cuts right through the mix. Great value and only 60 lbs.

pf350 a great head for the money!

I spent quite a while researching for a portable head that would have enough power and great tone but still fit within my budget and in my opinion ampeg came through with a perfect option, I have used it at least 3 times so far at jam sessions and was very pleased with how easy it was to dial in a tone that fit perfect and still keep up with 2 guitar players and a drummer!! The head had no problem at all cutting through and that was playing through a 4x10 he classic cab at 8ohms, I am looking forward to playing through this set up for many years to come, I had almost got the pf500 being worried the 350 would not hold up but I am glad that I settled on this head as it provided plenty of power & tone and fit better to my budget. And thanks to Sweetwater as they were excellent in their customer service and took care of everything right away with no hassle, I will defiantly go with them when I get the matching pf210 cab to go with the head!!
