hi, I'm about to buy a walkabout scout combo but i've only been able to try the 12' model. Has anyone also tried the 15' and can tell the differences in sound and if the 15's for example is too muddy or the 12' doesn't have enough low end compared to the 15' one? I loved the sound of the 12' but i tried once a BA115 ampeg and loved the 15' cab in it. Better lows. Also i have tried an ashdown combo with a 15' and found it too muddy.
