I like to gig with my full rig. I like the way it sounds, the way it looks, the way it's tall enough to hang my Bass off, the way I don't need to turn it up above half and only ever have to dig in for tone, not volume.
So what's going on in the head of someone who looks at me askance and says, irritably, "it's too much, you don't need it!" He's definitely sure I'm a wanker on that particular question.
If you, too, are deeply disturbed by what I'll freely agree is overkill, explain it to me so that I may soothe the old git before he has a heart attack.
My rig's nothing spectacular, I just bring both cabs where clearly one or the other would be more than enough.
I get that from people when I show up with my Ampeg B25B/B25B rig. It's 55 watts.
