A few points of suggestion- not trying to contradict others who have posted; if it appears that way it is only because I have info they may lack. My comments are much more agreement than contradiction with the poster, above. I have owned all of these amps (except the RI Jet, which I did play through quite a bit.)
The 90's Ampeg reissues that were 1x12's were usually made in China- these are "Jet" models, and have a reputation of poor reliability, but they have a very sweet tone. Ampeg did make a 212 "Reverberocket" (note the "e" in between the two words) that was much better put together, as I recall it was made in the USA.
I don't think you will get a Fender Deluxe Reverb for a grand, unless you come across a used one that the seller is trying to sell, fast. Vintage BF DR's bring over $2,000, SF DR's about $1500, and RI DR's... well, sun of a gun, you CAN get 'em, new, for about $1,000. You should give that amp serious consideration. (DR I own is a vintage SF.)
Fender's Hot Rod series fits well under your budget, even new, some reports of reliability issues on them, too. If you buy used and the amp is less than 5 years old, be sure to get the original sales receipt from the seller- Fender will transfer the warranty over IF you send them a copy of that receipt. Fender says "To take advantage of the 5-year transferable warranty, the original purchaser must endorse the sale of the product to the new owner on the original sales receipt. The duration of the transferred warranty will be the balance of time remaining up to five years from the original date of purchase of the product."
I like Peavey's Classic 30 and Delta Blues amps- both 30 watts, both available in a 112 config (DB also in a 210, and it adds tremolo), and they can be had, used, frequently, for as low as about $300.
Both Fender and Peavey have excellent customer support.
Two older amps you should also consider:
Fender Champ 25SE (non-SE models lack the effects loop, which I think will be essential for your uses.) Although a hybrid, it's power amp side is tube-drive 25 watts, and it has a very nice clean tone. It's distorted tone is way over the top, but ignore it and use pedals. For some reason, the reverb in mine does not play well with others (pedals) so I can't use both on-board reverb and effects reverb at the same time. These can be had for well south of $200.
Peavey Bravo- ignore the very dated styling- all tube 112 amp, 18 watts. Hard to find. Marshall-like tone for less than $250. Wish I still had one.
