Hi. As many other guitarists, I have an issue with my amp. It's too loud for my appartment. And it doesn't have a line out or headphone out so I want to use a modeller to play with headphones during the night Recommend me a powerful audio interface. I don't care about multiple inputs. I will only use one or hardly two. I want the best DSP's for the money to minimize latency and use effects. My budget is up to 250 bucks.
