Feature:
This amp is feature laden. The XLR mic level direct out is useful for gigging and recording. It tilts back which is nice. The headphone out is clean and hot, but this amp is a little big for a home practice amp so I have a feeling this feature is wasted on most of these, but it does work well. Ampeg's 5 position style switch is handy for fast "personality" changes. This amp has it going on in the tone control department. For me the best feature is the totally linear rotary tone controls. I thought they were wacky at first but now I love the tone controls and they have spoiled me. If you turn all three tone controls all the way down you have silenced the amp. That is total tone control. Amazing idea! Also I like the dual inputs. I can plug in one active bass and one passive bass at the same time and just turn up the volume on the one I want to play at the moment without having to switch cords or any of that stuff. I wish Ampeg's rack mount pro amps had this dual input feature! All the phone jacks are METAL, not plastic like on almost all the other brands. The jacks look just like the ones on my pro line Ampeg rack mount amps. The RCA/Phono jacks allow you to plug in a music source for play-along practice. Before you do that keep in mind that these RCA/Phono jacks go DIRECTLY into the power amp and whatever you plug into them are going to play at 100 watts with flat EQ, so make sure whatever you plug into them has its own built in volume control which should be turned all the way down to start and then turned up to normal listening level. The amp's rotary volume and tone controls have absolutely no control whatsoever over these RCA/Phono inputs.
Quality:
Ergonomical design disagreements apart, this is without a doubt the best sounding bass combo I've ever owned. Nope it isn't perfect, but close. I've never seen a perfect combo amp as there's always something I'd like to change or a feature I need that is missing on all combos. The Ba-115 speaker is rated 150 watts at 4 ohms, the amp only does 100 watts so this means you'll probably never blow the speaker and you'll for sure never need to haul around an extension cabinet. The jacks are all metal. The pots are nice and tight. The controls on mine haven't gotten the least bit scratchy with five years of steady use. It will take a few bumps no problem. I'd have no problem selling this five year old amp to my best friend as I know it has lots of life left. If you are gigging five nights a week or opening for the Stones then this probably is not the gig amp for you. But it will make you heard over a drummer at rehearsal and work great for small to medium gigs. For bigger gigs you can use the XLR out into the PA.
Value:
Spend less and you'll certainly get less. Spend more on another brand with equal wattage and even then you may still get less. If you want awesome clear, clean, rich bass sound, then you want an Ampeg. If you want a modern bass sound you want this Ampeg. If you want old school you want the Rocket BR100. Once you own an Ampeg, you'll probably never be happy with any other brand.
Desirability:
Well it isn't an 8 x 10 with a Classic perched on top, but if I had my choice between this combo and a combo from any other maker I know I'd take the Ampeg every single time. To a bass player few musical items are more appealing than that big "A" on the front of an amp.
Sound:
This amp has a really big sound. It sounds better than other combos I've tried. I liked it better than the sister Ampeg BR100 Rocket Bass amp because it has a tweeter that helps deliver a more modern bass sound and it has an XLR direct out while the Rocket has a phone output. The tweeter also makes the BA-115 extremely flexible so that it can be used for things other than just bass. The Ampeg Rocket BR-100 sounds really good with a bass but it is pretty much locked into being just a bass amp and it doesn't sound as modern to me. The BA-115 sounds very clean, clear, modern and non-distorted. Lots of people complain about hiss with this amp. This is because it has a very good tweeter. All transistor amps hiss friends, you just hear it sooner with this amp because of the tweeter. Here's what I do to minimize the hiss. Turn up the treble until you hear the hiss start, about 2:30 on mine, and then turn it down until the hiss drops out which is about 2:15 for me. Hiss problem solved. That should be all the treble anyone needs, even for a keyboard or harp player, and is way more treble than most other combos including the Ampeg BR-100 Rocket bass amp.
Ease of Use:
It takes some time to get used to the three rotary tone controls and to fiddle with the Style Switch to your tones, but other than the "get acquainted" period it is really easy to use. My favorite style settings for bass are 2 & 5. My favorite setting for practice is 3, which is flat. I just set it and forget it and then use the tone and volume controls on the instrument itself for any changes. There is a nice long power cord that is hard wired in so you can't lose it or leave it at home. There are several changes I would have made though if I was on the Ampeg design team. I wish it had handles on each side to augment the one on the top. The top handle alone just isn't enough for a 62 pound cube of these dimensions. Using the top handle in one hand while placing the other hand part way into one of the rear ports makes it more manageable. In this series the controls are at the rear of the amp and not the front. This isn't the handiest place for them, that is why I set it and forget it. The tilt back feature is nice sometimes, but I use mine upright most of the time. This amp WANTS to tilt back and it doesn't take much of a bump for it to rock back, so don't put any pedals, processors or drinks or anything like that on top or when it does tilt back, they'll slide off. The tilt back feature eliminates the option of using the amp as a stool. It also makes adding casters dicey which is why you never see any of these with casters. Unless they are the removable kind the tilt back feature won't work right with casters installed. When the amp is tilted back the controls are even LESS convenient to use. They could have put a tweeter level control on the back and I've actually seen these added by some owners of this model. I wish the RCA/Phono inputs had at least a volume control. These are small sacrifices for great sound at a rock bottom price though. This amp is relatively low priced when you consider the quality, a genuine bargain.
Support:
I've always gotten a fast answer to any email to Ampeg. They are without a doubt numero uno in customer support as far as I'm concerned. There are Ampeg service centers all over the USA and the world. I've never had anything Ampeg break since 1972 when my Ampeg BT25A needed work because of misuse after I turned it on without the speaker being connected. Even though it was my fault Ampeg fixed it!
Overall:
I owned this amp for over a year. It was at least 3 years old when I first got it. I've been using it for a practice amp. It is almost too big for that. I've also used it at a smallish gig. I'm planning on getting the smaller BA-112 or a used BA-110 or Rocket 50 at some point down the road as a practice amp and selling this combo. If I didn't have other Ampeg gig rigs I'd be keeping it for sure. For a bassist looking for their first Ampeg or for one Ampeg that can do it all, this is an excellent choice.
