Thanks for the info, especially about the Excalibur. One of the other posts said he thought it was just a cheap melodica with a pickup. Was that your imprression? When I run my Hammond through an amp, the volume on both the p.a. head and the instrument has to be jacked up almost all the way to get the volume I need. I live in Medford, Oregon. There’s a guy here who fixes accordions so he would be a good resource for me.
