Long story short, in 1999, I was rear ended while I was stopped on the freeway for a wreck immediately in front of me, by a car doing 70 mph... To say the least I have had back issues ever since then. This past weekend has been a particularly notable flare up, and it's got me giving some serious thought to my current amp setup... I own, and contrary to what others have said, I actually LIKE the tone of my Crate BX-100 amp. The power is pretty decent, although truth be told I would like something with more oomph. Where the crate gives me problems is moving it... At a stated 65 lbs (My scale says 70!) the Crate is downright beastly to wrangle in and out of my truck, ESPECIALLY with my back problems... I am giving some serious consideration to selling off my crate, as well as my MXB-10 practice amp that pretty much doesn't get used, in favor of buying a Fender Rumble 500. At 36.5 lbs the weight difference is HUGE, and goes from pushing a bad back, to the situation where I can deal with it pretty well... Mind you, just hauling from room to room is no biggie, I mean hand truck does great with that, and I can probably set up a ramp on my truck to just wheel the amp up in place cutting out a LOT of hte problem... But I still would like to upgrade. So I need help deciding. Which would be better, realizing that I likely will never do any gigs louder than coffee shops and praise and worship bands, and in most of those venues I would run from my amp to the board and house PA system... So the real emphasis on the amp is for a stage monitor use... I know I could go a LOT less money and go with the Rumble 100, but I was thinking about future-proofing myself with the 500. My concern is going to be the difference in tone between the 1x15 I am used to using, and the 2x10 of the fender combo... I try to play a variety of styles / music, but I gravitate toward deep lows / mids that a 1x15 seem to work so well for. I just wonder if a 2x10 will work well... And be worth the $$. Do the Rumble 100 or 200 have a 1x15 config?
