Comments about Ampeg PF-50T Portaflex 50W Tube Bass Amp Head:

This all tube head sounds awesome. It sounds like an Ampeg should sound. You can get anything from a warm fat bottom to very modern snappy tones. My only complaints have to do with the build quality. A lot of the connections/inputs are made of cheap plastic and eventually these will fail. Also the DI line out is not very clean at all .. very noisy. I have heard of problems with Ampeg's DI before but never experienced that problem myself until now.
If you want a great sounding amp for practice or small venues this is an awesome pick. If you want a heritage quality piece of hardware keep looking.


I wanted an SVT-Classic but the PF-50T caught my eye.

    Comments about Ampeg PF-50T Portaflex 50W Tube Bass Amp Head:

    I was initially concerned that this little guy could not keep up with a drummer or fill a room but I was very wrong. I am using it with a 4x10 cab and a 15 cab together at 4 ohms and it is plenty loud enough to hold it's own. I have to push it further than an SVT-Classic to get there but the sound is deep and clean and can certainly keep up for a small to medium gig... I have not yet tried the transformer output through a larger PA but I am looking forward to it... when I get a bigger gig that is.
