Take my trombone and play it...it even runs without solar energy (although I won't be able to do so after some time). Btw, how would you build solar panels in your scenario? ----- original Nachricht -------- So, let's say hypothetically a major catastrophe occurred in the next 2-3 decades, and power became non-existent (unlikely) or highly scarce. For example, suppose we all had to rely on solar panels and wind power, and powering an amp and looper was a complete luxury and out of the question. What would you do?
