Hi all, i'm a guitar player of 5 years or so and am looking to expand my sound. i'm thinking that a synth is the way to go. i've looked into it a bit and right now i think my best bet is the microkorg. i'm not worried much about the polyphony (that's how many notes will ring at the same time, right?). i'm just looking to be able to get a lot of decent synth sounds out of it. and with the korg, i read that you can plug a guitar into it to process the sound? how does that work? just plug it into it and then into an amp? i couldn't use my tube amp, right?

another synth i was looking at was the Realistic MG-1. i don't know much about that one, but it's affordable and sounds like it'll do the job.

i'm trying to keep this under like $400 US. could i use my 50W solid state guitar amp until i can save up enough for a keyboard amp?

i know i have a lot of questions, but, like i said, i'm new and am interested in the whole deal. thanks in advance for any help you guys can offer!
