I am using a 350 watt amp head and a set of ADA Basslines XL cabs. I blow the 2x10 routinely once a year, and while I am awaiting reconing, I am using the 15 alone. After a week or so of knob twiddling, I got this great sound by turning the treble down, but kicking in the high- boost button, and backing down the highs on the EQ, and bringing up the mids. Now the 2x10 has a tweeter, so will I still get the same sound? BTW, I used to do the "Smiley face", and always thought it was stupid, but everyone else (Guitar players) said it sounded great. Do you have any suggestions? Should I stick with the 15 till i get to play with the 2x10?
