I think the Electro is a perfect match for that module. If it had a harmonizer on board, I might have bitten, but I'd have to bring too many pieces to replace what I have now. (PA800) I wanted to try to incorporated my E3 into my live rig, but I'd miss the monitor speakers, harmonizer, sequencer/MP3 playback .... just not the perfect fit for my shows. If I used a bigger PA setup more often, I might have considered it, but I need small, fast and EZ to accommodate my one night, in-out jobs.
Try it - I'm pretty sure it'll be a great pairing.
