OK, so I'm a total novice, especially when it comes to effects, amps, etc. What I'm looking for is something simple and fairly cheap that will let me play along with a drum beat when I practice. I've seen a few people talking about cool drum beat apps for iPad. But, I'm not sure how I'd be able to hear that over the bass itself. So, I'm thinking about something that can play through my amp (Unless there is some way to play an iPad through my amp that I don't know about?). As far as the machine/pedal/app/whatever, I don't need much. Just looking to get a handful of preset beats that aren't too cheesy and will allow me to adjust the tempo. If it has more functionality that's cool (sampler, etc). But, I'm looking for something that will help me practice that won't take hours and hours to figure out how to program. So, what am I looking for? An iPad app and a way to play it louder? A piece of hardware that I can plug into my amp? I have no idea.
