I've been reading this thread for a few months and figured i should post about my experience with
my Rumble 100 combo now that i have had it for a little while.
I picked this up as a practice amp and never really intended to gig with it, hence why i went with the lower wattage 100 instead of the 500 combo.
However, I had a run of gigs last weekend that were relatively low volume (small pub dining area's) that my main rig would have been overkill so i decided to chance it and try the Rumble 100 in a live setting!
I won't go into full review mode here but there were a few things I discovered over the weekend that really helped the Rumble 100 cut it in a live situation!
I found that raising the amp off the floor, using a HPF (40Hz) and cutting the low end a little really helped clean up the stage sound. I was able to boost the low mids to retain some fullness.
I disengaged all the filters as they seemed to suck up a lot of the headroom and kept the gain at about 12'o clock and the master between 12 and 1. I felt like this was the usable limit of the amp without pushing it too hard.
I think the Rumble 100 is a great option for these kind of low volume gigs even without PA support. However, i wouldn't risk using it for anything much bigger than a room of about 50 people. You could maybe get away with a room of 100 with PA support if your drummer hits light.
If you're like me and play with a light touch and don't like a lot of volume onstage the Rumble 100 would work great for you but if you're a heavy hitter and like to FEEL the bottom end, the 500 would be the way to go.
Overall, i'm really impressed with the Rumble 100 and think it's a great bit of kit!
Here's mine paired up with my Franken P (Jaguar bass neck on a 69' P body with a J pickup added).
