I am resigned to the fact that I can't sing. But I still would like to sing something to give one band I play with more depth to our music. We play '90s indie rock style (Superchunk, Replacements, Dino Jr). Of course, the best answer would be something like an autotune, but those cost too much, so perhaps something to disguise my voice under tons of effects. Reverb, flanger, echo? The Digitech 300 looks pretty cheap used. Any other sub $150 alternatives?
