Hey markyboy,
just visit a good audio store in your quarter and ask to connect your Profiler to the best PA they have: it's the same concept of a flat cab, and you'll have a garsp about how (good) it sounds.
Also, become confident with the parameters in the Amp section: for example, try and lower Definition down, it's a good thing to give the sound a mellower tone.
Also, chances are you're using too much distortion: it's not needed with the Profiler as with many modellers. I'd try and clean it a bit.
Don't give up, the tone is there, like the Pietà in a block of marble: you just have to reach it
