In my experience the Tecamp stuff sits really well in a live mix. There is a comprehensive range of goodies onboard too. My Black Jag has boostable eq sections for High, Low and High Mids and Bass. I don't think the Pumas have this. There is also a Taste function which gives a wide range of tonal options and a really nice compressor. I also have a GB Streamliner which, in isolation, sounds fabulous, but tends to sound a bit woolly in a live setting. The Tecamp just cuts through all the time. Off your list I'd like to have a try with a GK MB Fusion.
