Subject: Re: Horizontal format multiple / Larry's magic bus

Hi Larry,

This sounds great. I agree with all your points, and while I had been
thinking of a two jack row strip, I think you are right in that it's just too
expensive and with one row (and say 7 different multiples), the jack one
needed would never be more than about 3&1/2" away. I'll have to look for the
"U" channel that you mention.

Keep us posted!
JB
