Acoustic Guitar with Piezo and Preamp to sound miked up

My first experiments in modeling acoustic guitar sound. Trying to find the best working wet/dry pairs! Played live in Valeton GP-5 with 0 db inputlevel works. To hear the model undistorted in the plugin the input level needs -20 db attentuation. The DAW is Ardour in Linux. Finaly the last model Duke 12.3 sounds nearly 95% as the microphone. Blindfold A/B check gets exciting. Unexpectedly lower ESR doesn't always sound better. Tips, tricks and ideas for improvements are very welcome. Of course you should build your own NAM for your specific guitar to get a good match.
