For a guitar, there are two main types — a Fender (or Fender-type) and a Gibson (or Gibson-type). I’m sure there’s a more technical and accurate way of describing it, but there we go.
I myself have always preferred Gibson types — and generally they are easier to play than the Fender types, and therefore probably a better bet for a beginner. They (can) have a nice fat sound with two humbuckers (double pickups). Epiphone is the ‘cheap’ version of Gibson — again, no point buying a 600 quid + guitar until you really know what you want and that you are going to continue playing. So, instead of, for example, getting a Gibson Les Paul, try an Epiphone Les Paul. It is to all intents and purposes the same, except some materials used in production are cheaper, and some production methods are cheaper. But there are some very very nice Epiphone Les Paul’s out there. Be warned though, that the Les Paul is a bloody heavy guitar. Another one to consider would be an Epiphone SG standard. This is thinner, and is like the Gibson SG that Andy played a lot around Infernal Love / Semi-Detached.
Martin uses a Gibson Flying V quite a lot, and I think Epiphone do a cheap version of that.
Having said that, if you want to make an investment, and have a guitar that you will love and cherish for twenty years, and you have saved up, go for the Gibson (or other more expensive) model.
The big tip is to go to the shop and try it… not all guitars are the same. Play various guitars until you find one model that you like, and then just try a couple more. If the assistants aren’t happy with that, walk out, with your cash.
As far as amps go, if you are practising in a bedroom or other small(ish) area, you probably won’t need more than a practice amp, say 25W. If you get a 100W amp like I decided to get (a Marshall Valvestate V100R) you will never get to crank it up above about 1 out of 10 unless you have a bit more space, don’t mind going deaf, or you buy a power break. You generally get better tones on amps when they are driven harder, so you are better off getting a smaller amp and turning it to 8/9/10 rather than a larger one at 1 or 2.
If you get a Marshall amp with a distortion channel, you will get nice distortion, and will have no need for an effects rack. If you do want to play around with an effect, choose one and try out the pedal in the shop. If you don’t know what effect in particular you want, consider a floor standing combination, like the Digitech RP series etc. These give you loads of different things like Phasers, Delays, Distortions, Wah, Flanger, Fuzz etc etc and can keep you occupied for hours, if that is your fancy.
