I bought this to replace an elderly Carlsbro I really liked, but we play a lot of festivals on outside stages and theatres with big stages and I needed something louder. I like 10" speakers so matched it to an Ashdown 8 x 10 cabinet.
I've got lots of behringer kit so when I saw this, I jumped straight in.
A year later, I'm really pleased I got it. It plays LOUD, it sounds good, and the controls are quite gentle and useful. I use two guitars - A Fender Jazz bass that has a higher action that I play hard, and a Peavey that is set up for jazzy bassy stuff, and gets played very gently. The amp copes with both of these perfectly.
I also do NOT look after it. It has a flight case, but has fell off cases in the van from a height, fell off the cab onto a hard floor loads of times and no ill effects.
I use the mute button quite a lot and this works silently. I rarely use it in anything other than clean mode - so the valve like emulations haven't been explored - I often have it very loud though and this doesn't cause any issues at all.
If I lost it - I'd simply buy another. It just does the job I need it to do with no fuss.
