Onboard effects and stuff you dont need.....You should get a good reliable amp that sounds great all by its self and add affects by using pedals or what have you.
If you get one of these ultra modern digital amps with onboard effects that only sound good when you have the effects turned on, what will you do when you don't like the effects it came with anymore?
Any Fender ALL TUBE amp will compliment a Strat very well. And when I SAY all tube I don't mean this crap Fender has come out with the past five years with channel selections and such. REAL all tube amps don't have flashing LEDs and intergrated circuit boards just hand soldered components wrapped up in fish board tubes and a light bulb.
Maybe I'm just too old..or maybe I just love the tone of old Fenders and hate to see what they are trying to call Fender these days.
Anyway.
To go with a classic match up that many players use including the pros, get a Deluxe Reverb.
They were made from 1963 to the late 70's and a Blackface reissue was made in 81-83. I think a reissue cam out a few years ago to.
A Deluxe Reverb is loud enough for gigs without a doubt but not so loud you can use it a home. It will break up just right for a Strat.
60's blackface models will go for around $900 for one in good shape but not mint.
The price drops if its a 70's silverface. Drops more for silverface with master volume pull out knob. Around $750.
The 80's reissues are still floating around pawnshops and the prices range wildly. Some people try to sell them as originals from the post CBS blackface days. A good rule, if it has a red three prong plug its most likely a 80's reissue. $650 is what I would pay for one.
Another super amp to get would be Princton Reverb. Its the Deluxes kid brother. Lower wattage but same great tone. The price scale for Princtons is about the same as the Deluxes but subtract $100 or so.
If you go with a vintage Fender you will need to shop around because prices varry from dealer to dealer and different parts of the country
