Wondering if any of you can explain the sonic differences through experience with the overdrive sounds of these amps in comparison to one another? Also, the 23 is said to break up rather early... I remember it doing so but it was fairly loud. Do you guys think its enough headroom to do channel switching for clean/overdriven sounds at a small to medium size gig? And lastly, what kind of headroom are we talking about on the LDW? I know im asking alot you guys are the best to ask. Thanks!
