Oh yeah! The good old CFM56-3 Jet Engines!

I do like the 737 Classics. They were a workhorse long before the NGs came along! I will be sad when British Airways get rid of their few remaining Classics in favour of A319s.Great soundset by the way. I've always noticed how different the Classics sound to the NGs. The older ones sound much gruffer and have that distinctive 'howl' when the power is advanced. The new NGs sound almost identical to the A319/320 family and just whine like a hoover!
