Hey thanks guys. It sounds like Russ is saying it's ok.

Well I wanted to keep things as simple as possible. One downside is that my guitar would have to get the same effect as my voice. My guitar - a Yamaha LL-TA has a reverb knob (and can get reverb and chorus without even pluggin in!!).

I guess that I can try the simple setup in a memory care venue, and if it doesn't work, I can get a 4 channel mixer. Since the guitar and the keyboard have effects, I would just need a cheap Rolls 4 channel mixer.

But having to bring and hook up along with the guitar - 1) instrument cable, 2) preamp, 3) preamp a/c adapter, 4) output audio cable for preamp, 5) mixer, 6) output audio cables for the mixer - it sounds like too much. This is addition to my keyboard, stand, mic, speakers, cables, pedals, adapter, etc.

Maybe I'll just play guitar in my room.
