In the past 50 years, tube amplification has come a long, long, way. Many of the early 50's Fender amplifiers are thought of as the holy grail of amps as far as tone goes due to the components used, and the fact they were hand assembled. While there is no doubt something special about the mid to late fifties Fender Amps, and as well as the guitars and bases that were built, there are currently many amps being built as well as amp clones, that are in the $500.00-2,000.00 price range that have amazing tone and pack a lot of bang for there buck. Here are a few specimens.....
The Fender Blues Jr.... I own this Amp and while it is a little guy, its in the $500.00 price range, and when you crank up the volume and let it start to break up, it has a great blues tone, and packs a nice little bunch... very respectable for the price
Victoria Amps....These guys are based out of the Naperville area, and I have a buddy who plays one and the tone is impressive. 2 channels and sounds great with an overdrive pedal. roughly $1500.00 msrp
Bad Cat Amps....These guys pack a nice little punch and are roughly 5-15 Watt beasts that can really shake you up
Mesa Boogie have a reputation for a reason. They have been around forever and have nice tone and tubes that help you find whatever tone you're looking for from Rock to Jazz and inbetween
This is the amp you dream of the highly sought after Dumble. Not many exist and if you find a legit original expect to pay in excess of 20k!!!!!!! but the tone is unmistakable and some of the greats have sworn by them, specifically SRV!
