Just got home after driving all day in the motorhome, so I will start fresh tomorrow.
The first test I'm going to do is to set them both flat and compare the sound of my DB'1 Piezo through each of them to see if the new model eliminates 'Piezo Quack'
I'm going to record it both through the amp and speaker and also the DI from the amp. I will try both pizz and arco.
If you have any ideas of what you'd like me to test just let me know.
Thanks
