I love it. It's dead easy to get a great sound, whether retro or modern. I have it running through an Eden 4 x 10 (4 ohm) cab so the amp is delivering the full 350 watts but I'll deffo get the Ampeg 1 x 15 soon!

Great. I bought this to use with a TC212 cab for rehearsals and pub gigs, and it's great so far.
Nice clear sound, plenty of power
Feels well made. There's a lot of metal to the case, and it feels sturdy
(not important, but it looks cool as well)
I'm using it with a Yamaha active bass with the -15dB pad switched off.
I haven't run it in 350W mode as I only have the single 8 Ohm, but I doubt it would struggle. Big clean sound.

great little bass amp. very light and very loud with the matching cab although I havnt tested it in a live situiation yet but im sure it will be fine.

Chosen over the 500 because I didn't need the extras on the 500.
Sounded great and was wonderful with a PF115HE cab for an all day recording session the next day. Unhappily didn't work the next time I took it out but, credit to Andertons, it was replaced by the 500 and that is a superb piece of kit.
The 350 sounded brilliant but I just got a dodgy one. Don't let put you off an excellent head.

Initial reaction out of the box = hell this thing is tiny. Its not as tiny as the GK MB200, I cant fit it into the pocket on my bass bag but it fits into a backpack easily. Its really well made and I reckon it could take a drop or two; not that im willing to test that theory. Now this is my first experience with Ampeg. Closest thing to an Ampeg amp ive used before is presets on podfarm and a tech21 PBDDI. It doesnt have any growley gain too it. Its a very clean, solid state sound. That being said, it sounds beautiful. At home im pushing it through an Ashdown ABM115. This thing pushes out a lot of bass, even if you leave the bass control flat. The other thing I noticed whilst practicing, and whilst recording through ProTools, is that it has a LOT of mids to its sound. You can cut this obviously, which i have being doing slightly, but it still has a very punchy, clear midrange sound to it. (it might be worth noting that the mid control cuts and boosts at 500Hz) Personally, I love it. For recording this thing is absolutely beautiful, the DI out is post EQ and the volume control on the amp does not affect DI output. If I get any time, ill upload some samples of what this baby sounds like. I also want to point out, that the bass Ive been using with this thing is an Ibanez with an active pre. The manual says that if the "peak" light on the front of the head lights up often, you should use the pad button, which I have been doing. This obviously cuts the volume by -15dB. I imagine that with a passive bass, this head could be pushed a lot more.
The other night, I got to use this head at a large practice room, with a hard hitting drummer, two guitarists and a singer through a PA (should have seen ther faces when i whipped out this little tiny head out of my backpack). I didnt take down the Ashdown cab, I was using a Trace Elliot 1x15 cab 8ohm (so was running the head at 250w). When i first plugged in I panicked a bit, cause i had to put the gain and the volume almost on full to hear it. This wasnt too much of a concern because the peak light didnt light up at all, but the limiter button was pushed in and the light to tell you that it was kicking in was doing so on every note played. Now i know this might seem strange, but after about 15 minutes, I dunno if it was my ears settling or the band getting quieter or what, but I turned the volume and gain down to about half and it was cutting through brilliant. Huge amounts of bass being pumped out, very midrangey punchy sound and even through a 1x15", the highs were very clear and audible. We were playing rock/funk covers, and we even played some reggae at one point. This head is very versatile, im over the moon about it. Next step on my list is to buy a 4ohm lightweight cab and run this thing at 350w so I can have the gain and volume knobs running even lower! I really dont know what people are comparing this head to when they claim that it is quiet for a 250w. It seems as loud as any 250w combo ive ever used.
So to sum it all up, I definitely recommend this amp, wether it be just for a nice clean recording tool at home or in the studio, or for gigging. Id venture a guess that this thing would struggle at large gigs without a PA, but saying that, Im yet to run it at 350w.
