Ok. I got this used Rumble 500 a few days ago and am incredibly disappointed to realize that this might be the only amp I really need.
Its feature set works great for home practice. Its footprint is pretty small. It gets loud enough for smaller gigs and rehearsals. It can take an extension cab if needed for louder venues. It has a direct out although it's kinda odd that the master volume affects the output. It has an effects loop for those who like such things.
So what am I supposed to do with the rest of my amps???
I really like my GK 400RB and 800RB and BagEnd cabs.
I might not really need these anymore….
Yeah, the Rumble has a baked in warm-ish tone, but it can be scooped and brighter with the right EQ settings. Is it perfect? No, but it does what it needs to do for what I need these days. Plus I can carry it easily with one hand. It might be the best amp I've owned because it's so versatile.
I can see how folks might not love the overall tone, and it's certainly not boutique, but it is a very practical piece of gear.
