I just joined the Marching Lumberjacks (school's band). And I need an amp for marching. The other bass player has a Crate Limo strapped to his back (with a backpack frame and bungie chords). I don't think my back could handle that. (especially with all the hopping around I'm sure I'll be doing) I guess my real question is which portable Crate amp I should put in a red wagon and have a fellow rookie tote around for me. I like the Limo's tone and wattage, but is the 20 watts all that big a difference in loudness? I'm running on the "broke college student" budget at this point (using savings bonds to buy it).
