I've chosen these 4 brands. I know there I am missing a few good ones such as Hartke and Roland. Despite the price difference, which amp do you personally think is worth every penny? - Fender Bassman 100 Combo (The 2005 solid-state model) for $349.99 US - Yorkville XM100C for $329.99 US - Ampeg BA115 for $449.99 US - SWR Workingman's 12 for $449.99 US Please feel free to vote. Thanks!
