[Dixielandjazz] Bass Keyboard

[Edmetzsr at aol.com]

Listmates, 
    For a special need that has surfaced, I'm looking for (in the market for) 
a bass keyboard device. Over the years I've owned bass pedals and other 
synthesizers to allow me to play bass lines in small club date settings (which I no 
longer have). Now, as I search for a new device, I find lots of midi 
controllers, USB port devices for computer interfaces, etc., but no direct "plug into 
an amplifier" and go devices. Can anyone lend a hand? 
I'd be deeply indebted!! Thanks
