I very recently bought a rumble 100 coming from a rumble 15, I use the rumble 100 for band practice without PA with volume at 50 and gain around 40, I use it also for giga as stage monitor with a gain on 50 and volume around 75-80%, we play usually around 2-3 hours and we play maybe once or twice a month and practice once a week, do you think this little beast can take that use without any issue for a long period of time?
