The new Fender Rumble 100 arrived today and I just got a chance to check it out a little bit. I need to put on new strings and give the P Bass a set up before I fully run it through some paces, but my initial impressions are pretty wow! The amp is light light light! Holy cow, I'd read about how light it was, but didn't really grasp just how it would really feel. We're talking one-finger-lift light. Crazy. I really like the different voicing options it has. On just a quick play, I found some nice tones pretty easy with some small low end cuts and some slight high end boosts with the Vintage and Bright buttons engaged. I didn't think I'd like the Overdrive, but I have to say that it sounds really raunchy. Dig it! It's smaller than my little Marshall by just a little bit, though it's deeper so it's got to go underneath for now until I get everything set up in the new basement studio in a few months. Can't wait to crank it up when everyone is out of the house tomorrow!!
