Musical Equipment For Touring

I am a Frank Zappa alum, i am retired but i get to perform once in awhile. Recently my amplifier went the way of all things that have given great service, but their usefulness has declined, and finally went the way of the Dodo bird.
I now have the opportunity to be a part of a great touring experience, but funds to purchase a new amp are totally out of reach. The tour starts in May ( rehearsals in mid May ).
 I am blessed with the friends that i have made in and around music, and hope that i can get enough funding to purchase a great piece of
equipment that can represent the cool music we will be playing. I would be forever grateful for your help in making more great music, and thanks for many years of pure joy, we all know that " music is the best " .
