You might check out the Fender can. I used one for busking in Portsmouth N.H. a few years ago. Ran two Shure 58's and a keyboard through a mini-mixer. It had plenty of volume, but no reverb. Has a 12 volt batt. that lasts for about 6 hrs. bullfrdog ************************************************** www.harmonicaworkshops.com www.roundhouseblues.com
