Which is kind of where I'm at really, like you say, 22kg is hardly a behemoth, it is manageable, but shaving a few kilo's would be nice. Need to figure out how to get the grille off without damaging anything, and then maybe look at some Neodymium speakers. And as @neepheid was saying, the market place up here is a bit rubbish. For even a subtle divergence from the "run of the mill", I'd need to go to Glasgow at the least, and even further afield if I wanted to try anything "out of the ordinary".
If the Rumble's pre-amp sounds a bit generic, then that's not really an issue, as I'm just plugging into the Effects Return anyway, and using the POD as the pre. Need to get some time with the FlyRig and get that dialled in.
Been looking at the Barefaced One10 with their Activier amp, which according to their blurb is the equivalent to a 500w Class D.
Thanks for the info folks. 👍
