Update:
I gave Lounge Lizard a full two week demo. It was pretty darn good. I compared it to my Kontakt Scarbee library over and over again.
I noticed that Lounge Lizard had used a small increase in CPU activity compared to Kontakt 5.
It seemed to me as if the dry sound was nearly identical when comparing the two even though one is sampled and one is modeled. The modeling sounded, to me, just like the recorded samples... which I thought was a great accomplishment on the part of AAS.
I felt as if the Scarbee patch's effects were much more detailed sounding and the modulation effects had more sense of "movement".
I couldn't get enthused about spending money on another piece of software that didn't leave me thinking it would be a "go to" choice so I passed on the sale price and after missing that opportunity the decision became even easier.
I admired the demos of Sonic Couture's Broken Whurli, but I realize that I have a ReAmp patch laid out all the time and a room full of amps, and if I try hard I can scrounge up a broken speaker too. I'm going to try using Scarbee through real amps before I spend $99 on another sample library.
Thanks for all the suggestions, opinions, and insights.
It has worked out ok, because I was just offered a once in a lifetime deal on a custom hand made L-00 acoustic guitar from a batch commissioned by a friend of mine. He has chosen a couple to keep for himself and is taking the rest to the guitar shows to sell at full price, but he has offered to let me have one for the cost of the wood.
Software with a lifespan of a couple years or a guitar that will last 100 years? I did the math.
Now I need to save up for some nice strings. ;-)
