I've been busy so haven't had a chance to post, but about those 112 cabs... there should be a word stronger than "love."
They get the job done is a way that really can't be beaten. I love the midrange of 15's, but sometimes they can get boomy and othertimes just weird. The rumble 112's have a lot of the midrange bark of a 15, but IME none of the boom.
In gigging with them recently I've pretty much abandoned my combo 500 in favor of the 500 head and either one or two 112's... and you can't believe how well the 112 works by itself for a gig. in any reasonably-volumed band, a single should work fine, but the two 112's add meat to the midrange, and especially, raise the upper speaker where you can actually hear it. Note however that it takes more juice to get the 12's up to the same volume as the 210 - if you like the volume of the 500 combo at about 10 o'clock, expect to put the rumble 500 head's volume around 12 o'clock.
Someone said that Fender recommends placing the 112 on the floor, and I agree. I've had mine in the air about chest high, and it loses all bottom. put in on the floor and it suddenly doubles in volume and quadruples in depth. and still no boom.
and they weigh next to nothing and take up very little space. two in the backseat is an easy thing. try that with a 410.
as for my 500 combo - it's my practice amp now. backup if I ever need one. I've had it in situations where it was as boomy as anything you can imagine, so even though I still like it a lot and am not selling it, the 112 cabs sound so much better...
and an important thing worth noting - I've been playing around with mixing and matching cabs and amps - combinations of rumble 500 head, Rumble 500 combo, GK MB800, MarkBass LM800, GK Neo115-III, Rumble 112. The short of it is that the Rumble amp seems to make up the bulk of the sound we all seem to like, so don't make the mistake of thinking it's all the cab. It's the combination.To use a football analogy, It seems like the Rumble amps gets to you the red zone, but the cabs take you home.
So this weekend gonna stretch out with the two 112s. looking forward to it!
ps: for those following my war with the loud guitar player, he bought a Laney 5W combo. It sounds killer, and the volume came down dramatically. But he's having issues with it, so I'm sure it's back to the Fender this weekend. we'll see how those Rumble 12's work him over...
