Take your guitar to a shop (if possible) and try a bunch for a potential budget. Usual suspects apply: Marshall, Fender, Blackstar, Vox, etc. Personally, I always seem to veer towards Fender, or Fender style amps, but that’s just my preference.
I’m a big fan of Yammy Pacificas, a guitar that has always punched above its price point, no matter which level of Pacifica it is. I don’t know much about your amp, other than it’s very small and it’s this where I think your issue might lay. Try and use your guitar through a bigger amp, if possible, and see how that sounds to you.
