I didn't consider any other amps when I made this purchase. I've been using EBS equipment for about 5 years now exclusively and I've been very pleased with every aspect of it. For this purchase decision, I was wanting a smaller amp to carry around, and one that wasn't quite as powerful as the Fafner for smaller, lower volume gigs. The HD350 seems perfectly suited to the use I had in mind for it.
Favorite aspects: it looks good, sounds great, gives me a very similar sound to the amps I'd been using without the weight, and is very easy to dial in a sound.
I think EBS bass gear is the very best available and even though it's not maybe as easy to find, or as visible through advertising, etc. as some other brands, I think it's well worth checking out. It lets me hear what I need to hear to play as good as I can, gig after gig.

The tone controls on this solid state amp are simple yet effective. There's the usual bass, treble, mid range w/freq adjustment. In addition to these, there is a filter (tone) bypass, a button which activates EBS' character circuit which I believe is intended to be a tube amp simulation effect, a drive control which acts as a tone intensifier somewhat like adding tube distortion. The head seems very powerful, more so than the 350watts it's rated at.
So far I've only used it with the classic rock band I work with regularly. I've used it to power an Epifani 2x12 and also an EBS cabinet with a 15", a 10", and a tweeter. It seems to work equally well with either cabinet. The amp is not noisy at all. It's very quiet in fact. It sounds similar to the EBS Fafner heads I had been using, although not quite as tube like as the Fafner which does actually have a tube in the preamp circuit. The HD350 sounds similar to the Fafner in that it doesn't add it's own sound to the equation the way so many other amps seem to. It amplifies your instrument as it should and does nothing more until you add tone filtering via the tone knobs.
The HD350 is very simple to use. It's got enough features including built in DI, without being complicated to operate. The design and look of the amp is very solid, clean, and high quality.
So far it's been reliable. It seems to be very tough. It is fan cooled and doesn't feel warm to the touch even after a long, loud gig. The chassis seems very sturdy.
