Given the Super Champ XD's 15 watt output is tube, and the Cube 60's 60 watt output is solid state, can anyone compare the loudness of one relative to the other? Assume you upgraded the SCXD's speaker up to a RC or were going thru a decent 1x12 cab instead of the stock speaker. I've got a SCXD and really like it, but have an opportunity to pick up a Cube 60 too. I'm just wondering if the Cube 60 offers any more small gig-worthiness than the SCXD I already have. I'm happy with the models with the SCXD and only use a little delay or reverb anyway.
