    Brilliant sound, and awesome power for such a small head! I think I'll be looking for my ideal sound for a lobg time such are the options on offer!

    This light weight Ampeg gear really punches above its weight. I have gigged with it over the last month and it' sounds wonderful. It's clear, punchy with that great Ampeg sound.

    Highly recommended.

    Classic Ampeg sound from an amazingly small package. Holds it's own easily in small to medium sized venues without the need to run through the p.a.

    An excellent head which I have used live, in rehearsal and in the studio.

    Sounds great with my passive basses and has a whole bunch of great features. Incredible value foir the price and a great sound. The best combination!

    Had it a month so far and I'm very impressed. Done several practices and 1 gig.

    I've yet to really play around with the tone controls, I just set everything flat - plugged in and it sounded awesome straight off. Other reviewers mentioned the US power cord (mine came with a 3 pin) and potentially fragile controls but I haven't found that to be an issue.

    I bought the amp along with the PF-115HLF cab and attached the amp to the flip top lid so when storing and transporting the amp part is hidden away. Note that the head will only fit one way on the lid - check carefully first as I got it wrong the first time around.

    In terms of sound/tone it's great for what I play (60s/70s/80s rock/blues covers) and the comments from band members is that it looks and sounds great.

    It has a built in compressor but I favour using my own external one, just cos with my existing compressor I can dial in exactly the setting I want.

    For our band it's plenty loud enough and we only put vocals through the PA, but it has a DI output if you need to use it.

    still getting used to amp but seems to perform well.Tone controls make quite a differance and can get a variety of sounds.Setting up the fliptop option is a bit fiddly but worth it.One major gripe,amp comes with a two pin power lead which you cant use in a british socket.

    bought a couple of weeks ago, gigged it twice, rehersed it twice as well. Pros, good sound, light, cheap. Cons, dials feel a bit flimsy.

    If you're after the Ampeg sound, this is a good entry point for the price. You're not getting the SVT sound obviously, but you aren't getting the weight or cost either.Stick a decent tube preamp pedal in front and you're almost there. Loud enough for my 3 piece rock band for pub stuff, Di to PA for bigger venues is handy. Switchable EQ and bass boost also good. For the money (£300) this is a bargain and its Ampeg so you wont feel ashamed of it sitting on your cabs! My only concern was the dials all feel a bit cheap and flimsy so we shall see how long they last. Quite "toppy" as well i thought but that could be my bass (Jap Fender P/J) but easy enough to dial in your sound with quite a good EQ. 4 stars from me, but its early days!
