So i got a line 6 spider 3 15 watt and im not really satisfied with its sound, its just too muddy

i play my friends marshall and its sound is so much cleaner than my spider, and we have the same guitar

can anyone suggest to me the most clean sounding amp for around $100-200?
Vox AC4 or Fender Super Champ XD? Over your budget but both have nice cleans.
The Super Champ is only $100 over your budget. It won't take long to save up that much more. It's not really an emergency so you should wait until then.
