Feature:
Just what you need. Not a lot of knobs an buttons to press. Easy to set up.

Quality:
No more point to point wiring, but other than that it's a solid piece of equitment. I have a early 70's v4, and that thing is heavy. The classic series are not as heavy (smaller transformers I guess), and they don't break up quite as fast too.

Value:
If you want good tube sound, with out breaking your back moving it around, this is a good choice.

Desirability:
It's the classic ampeg look, only black. Not bad, but I do like the vintage look better.

Sound:
A nice, deep, round, and full tube sound. I use a 4 ohm 4-10 hlf, an 8 ohm 2-10 ampeg cabinet and an Eden 1-15 8 ohm cab.The v4 sounds great using any of my cabinets. I play passive basses throught it, and they all sound great. Crank up ther gain and master if you like that tube disstortion sound. I have a friend that has an Ashdown MAG 500 head, and he loves the tone from the v-4b. I think he's looking to get one too.

Ease of Use:
Easy tube tone to dial in.

Support:
I broke a knob off it moving it around. They answered the phone, and mailed me some replacements quickly. So, I guess they're OK with me.

Overall:
Again, good tube tone and easy to dial in.
