Right Then. New Head.

I'm in a Pop-Punk band, But i also play hardcore music and metal.

I was thinking a TSL60, or a DSL50, maybe?

Any ideas? Nothing too expensive as I'm not buying it, my dad is and I don't want him spending LOADS.

If you want to stick to Marshall, a JCM 900 might work.

If you think you can push Dad a little further, possibly some sort of Orange (Thunderverb/Rockerverb).

Some sort of mesa. I know a lot of PP bands use Orange. See if you can milk your dad for a little more. Look into a JCM800 too.
