Pros - Simple and effective 3-band EQ, Aux in, light and very portable, Good to practice alone with, Ruggedly built
Cons - No frills at all, can't get very loud without totally farting out, automatic compressed tone that can't be adjusted
This is a decent practice amp if all you're looking for is something to practice your chops on by yourself. But if you want headroom, look elsewhere cause this thing has none. It doesn't get loud enough to play with even a quiet drummer without losing all of it's balls. I've compared it to the Ampeg equivalent and the Ampeg preforms better on all accounts hands down, in the same price range. Louder, deeper, cleaner tone, and more versatile.
The MAJOR problem I have with the Orange crush 50BXT is that it sounds like it has a built-in soft-knee compression that totally squashes your tone regardless of your playing style. It almost deceives you into hearing a good "clear" tone, within a certain volume, but it's not actually your bass' tone. It's not user-adjustable and they don't even mention that the amp has this trait. The only reason i can imagine for this being designed into the amp is to possibly protect the speaker from loud volumes, which I consider poor amp design in the first place if that's necessary.
The tone sounds pretty good if you're playing softly and just want to practice your playing by yourself or with a quiet guitarist, but if you want to plug a bass into it to get a picture of the bass's sound or tonal range then you are S.O.L. This thing will lie to you about what a bass sounds like, which you will quickly realize in A/B-ing it with any other amp. The Ampeg BA-112 gets way louder, with much better bass response and you can actually hear your bass' character clearly through the speaker. Can't say the same for the Orange Crush.
All-in-all, I have to say this amp is not worth the price range it's in. You are better off with the Ampeg counter-part.
