I am slowly going crazy trying to decide which cabinets to buy. Of all the guitars, keyboards, amps etc. I have ever purchased, nothing even comes close to the amount of time I've spent thinking about this. I'm leaning toward an Ampeg 1x15 with a 2x10. I'd like to go with a bigger cab, like the 8x10, but portability is an issue. Do bigger cabs make that much of a difference in sound quality? Maybe a better choice would be the 4x10 on top of the 15? I know that it's a decision that I have to make, but any advice I can get would be appreciated. Thanks, Len.
