Feature:
Active/passive Imputs, level for the preamp, 5 band EQ, Direct Inject XLR, push-button deep/bright boosts, sub-harmonic with level (which you have to play with it to get it to make a big difference), effects send/return, and a tuner/line out 1/4 jack. The only thing I would have changed would be a speakon output, but it's not a neccessity.

Quality:
I thought since I had a warm studio, and people constantly have heads over-heat on them, I would have to get a seperate fan on it, but after the first use, I noticed out the side vents, it was blowing out cold air. My head is staying nice and cool. All the jacks are secure, and the knobs are staying right where they are. Definatly NOT a piece of junk!

Value:
Way better than most of the other heads I was looking at buying. This being the middle of the road ashdown, it blows new ampeg, swr, GK, and Fender out of the water. Though top TOP end Ampeg is better than this, I believe Top end ashdown might be better.

Desirability:
silver with black? always a good mix. Plus, the vu meter gives it that Sophisticated Look. Like the cab I got with it, first day, had to give it a hump. :P

Sound:
Very Much in love with this thing! I play it through a mag410, and I can't belive how great the sound is! you can set your EQ, or at the push of a button, use an internal preset, and I am still just using the preset it is that good! Honestly, after this, I am sticking ONLY with Ashdown!

Support:
Never had to deal with them, but all I hear is good things!

Overall:
Try this or other Ashdown before buying something else. I was SO sure that I had to spend alot of money getting an ampeg setup for the tone I wanted. I took a chance and ordered this because of the Ashdown reviews, and I think I made a better choice!

Feature:
Would like to see a pad on the DI and a footswitch for the sub-harmonics, but other than that, it has all I've been looking for.

Quality:
One of our roadies dropped mine at a recording studio ... and I mean DROPPED it! Plugged it in and, except for the light on the meter not working, it played like it just came out of the box. In about 30 minutes, the light came on!!! Must have been in shock.

Value:
This amp sells for slightly more than the Behringer "knock-off" of it, but is a substantially better built amp. It is, in my opinion, one of the best amp bargains out there, if you're looking for a good, simple, reliable, all-purpose amp.

Desirability:
Love the meter. Love the big knobs. Love the passive/active inputs. Love the XLR D.I.. Love the Sub-harmonics. I mean, who wouldn't find this little amp sexy?

Sound:
This amp has one of the best tones I've ever used. I've owned and played Hartke, Ampeg, Eden, SWR ... and an old 65 Black face Fender Bassman. This amp gives me some great tones, from growl to mellow.

Support:
In my opinion, support begins at building a quality product so that support is NOT needed. I've never needed it, so that means they did an outstanding job of building support into the amp before it shipped!

Overall:
I am going to purchase the MAG600 rack head, using this head with my 2 112 Aguilar cabs for venues of up to 300 people, then using the 600 and a 4X10 and a 15" cab for larger venues. I also use this amp in the recording studio.

Feature:
Seems to be built like a brick house. More EQ options would have been nice,other than that no complaints for the price.

Quality:
Appears to be made quite well. No problems yet,thankfully.

Value:
This is great value!! A pro sounding head that can be used in any genre. More expensive amps I tried did'nt come close to this one sound wise.

Desirability:
Practical addition. But it does look cool in a 1950's submarine equipment vibe. Unique against the other heads for sure.

Sound:
This head has a nice warm sound that really works for oldies and classic rock.With an Ibanez semi-hollow artcore and a Peavey 4x10 the Ashdown has punch and yet retains the bottom.No complaints for the price.

Support:
Have not had reason to deal with them.

Overall:
I hope to continue gigging with this for a long while. So far so good.

Sound:
The sound is versatile. With just the right amount of EQ avaiable and the power for small clubing it's perfect.
