Why would you replace it. I have used mine in clubs with room for 50 people to ones that would hold 500 and I sounds great at low volume or rumbling. I haven't had to turn it past 4 yet.
Sound
This amp is awesome! I had a Peavey 450 head and of course it had the transistor amp hum. This amp makes no noise at all! Will sound any way you want it to. I'm in a bar band and use a Peavey 4/10 and a 1/15 and it sounds great! You can feel the sound. I hope to get the Ampeg versions of the two cabinets I have. I have been playing bass for over 30 years and this is my dream head.
Features
Who needs accessories, its all in the head.
Ease of Use
The factory suggested settings get just about any sound you would need with little tweaking. The manual is short and to the point.
Quality
The amp arrived in perfect condition and ready to go. I have had no problems at all. I don't see ever having to replace it.
Value
This amp is every bit as good as the tube head at 2/3's the price. Combines the best of both worlds, the punch of the tubes with the power of the solid state, without the hum!
Manufacturer Support
Had no need to contact them.
The Wow Factor
All I have to say is, "its an Ampeg"! Who cares what it looks like.
