Not really a recording question, but this is probably the best forum for it anyway. I want to run my guitar through my Vox Tonelab LE and musical output from my computer into a mixer and then out to a pair of powered studio monitors so I can play along with mp3s, CDs, etc. Will a decent pair of powered studio monitors be able to handle that kind of output? The ToneLab would be set to a line level output. If it would work -- does anyone do this? Does it work well?
