OK I know this is a really noobish question but f*ck it I am a noob so here goes:

I have a pretty crappy-sounding 15w practice amp. Now my question is - if I bought a really good/decent effects pedal or overdrive/distortion pedal would it sound good or would the crappy amp make it sound bad as well?

For the most part your tone starts with your amp so if you start with something bad it's not very easy to make it sound any better and sometimes it'll make it sound worse.

a crappy amp will make everything sound bad.
I like analogue Solid State amps that make no effort to be "tube-like", and I'm proud of it...

...A little too proud, to be honest.
A pedal works with what's already inside of an amp, if the amps no good, the pedal will do close to nothing in terms of tone improvement.
