I need a very small, light amp with a line out to use as a personal monitor. The line out would go to our band's mixing board to be played through a PA. I'd really like a super small, very portable amp. It doesn't need a ton of volume, we play in small venues and don't play very loud. I have an Ibanez 35 watt amp now that works, but I'd really like something smaller. I thought the Roland Cube 30 would work well, but I understand it goes silent when you plug into the Record Out jack. I guess this is because it doubles as a headphone jack. Any ideas would be appreciated. Thanks!
