I am pretty new at this bass gig and need some advice on stepping up to a bigger amp for outdoor use. I am currently using an Ibanez SW65 that I have used for indor practice or I run a 1/4" out to a board and use it as a stage monitor. It works ok indoors but outside it gets snuffed by everything. For practice our band is using a an six channel Yamaha PA system thats rated at 300 watts. We run vocals, 2 guitars and a Roland Keyboard through it. The bass player has to amplify on his own, and of course the drums are on thier own. This set up is used for practice on a back patio that is covered with a solid roof. With 300 watts we are not playing at insane volumes either. Of course 65 watts is not going to be heard at all in this mess. I would like to step up to a bigger amp but I don't want to get into a huge stack just yet. I just need something to be heard. But I don't want to go out and buy something and find out it's not enough. What do you think????
