Yes, LBXII does have a very fendery clean (LBXI had less and more driven sound). Plus the modern hi-gain. Cannot predict how would the two pickups sets react to 5150. But it’s interesting you say you don’t care for the split sounds. These in-between positions tend to be my favourite. So, the HFS don’t split well? Would you say HFS is good for the modern playing styles (clear tapping notes, good string separation in distorted complex chords..)?
