So I currently own a Line 6 Spider III 15 watt (yup, terrible). I only play guitar at home so don't need anything big or expensive, looking to spend up to £100. I want something that will be good for blues/jazz but also allow me to play some rock/metal (if an amp like that for the price I want to spend actually exists). If I can't get an amp like this, what would be a good amp/s for each specific genre (blues/jazz and rock/metal) in that price range?

The guitar I have is an Ibanez GRG170DX.

Thanks for your help
Well a microcube... Or suck it up for now and just save.
I wondered why the frisbee was getting bigger, then it hit me.
vox ad15vt would be good, more on the bluesy side than the cube.
