Hi folks, My beloved but ancient Korg Pandora is acting up. While I am hopeful that I can figure out what's wrong, I may have to just get something new. Can you recommend a good replacement? I really only use it for headphone practice, so my important features are headphone output (naturally), aux in for mp3 or similar, and decent sound. I like having amp modeling, don't care much about effects beyond a bit of grit and maybe compression, but I'm not against them, either. Please tell me what you would or do use. Thanks for suggestions!
