I have the Korg Toneworks Pandora PX3-B. I have some "real" effects pedals that would be nice to use with it while practicing with headphones. Being a tech-stooge, I don't know if these peripheral effects would damage the PX3-B, (like an EBS Multichorus and an Akai Deep Impact). If you have experience using pedals with it and/or if you're not a tech-dummy as am I, I'd appreciate your input. (As you may know, getting in contact with Korg is like getting an audience with the Pope) Thanks much!
