I had a similar v30 experience, but more with my c+. Always was loving it with V30’s thinking it couldn’t get much better, but the orange JBL D120F’s really took it to another level. With what I have now V30’s are obsolete for me honestly
FWIW, not sure which prerolas you tried in that cab, they all sound really good (I’ve got also a 25 Watt M magnet 75hz one), but the 20w one is very different sounding and feeling and for the stuff you play would def choose a 20w one over 25 (much tighter, faster, more aggressive, brighter, biting, no honky mid bump). Even the current Heritage 20’s sound great imo, but honestly nothing compared to my pre-rola one. It is the brightest speaker I’ve had though and not very thick, but very efficient and cutting. It’s kinda like a eating a lemon, but there’s still lots of rich flavor behind all the sour bite. I can’t get over how much I love it, but maybe too bright for some
Will be curious how the D130F’s translate in recording. For my friend’s re-amp we found the D120F’s too hollow as a whole quad, but worked really great when we crossed them with my ‘60’s Blues. His style is more punk/alt rock type stuff though fwiw. I know very little about recording and left that stuff to him, but seems like he knows what he’s doing
