I bought a new Sov Horn 3 1/2 years ago. When I first got it it seemed fine, recently though, it feels like I'm trying to blow up a balloon when I'm playing! I regularly run soapy water and clear water through it, it occasionally has a soak in the bath, and I clean the piping with a 'thingy bob' (can't remember what you call them). But it still feels like there is something partially blocking. Anyone any ideas on how to solve this problem before I end up throwing it through the window? (Joke) Even considering buying a new one, but seems a bit much after only 3 years or so!
