I was working with the fretless features on the BP-50. I will tell you that results may vary depeding on what bass you are using. This it with a Ibanez Soundgear GSR-200 Bass. It has a P and J pickup configuration and is passive. Ok to the Jeff Ament effect. EQ Treble 3 Mid 6 Bass 5 Noise Gate: G5 Amp Model: Trace Elliot Commando with the gain on 3. T3 Compresion: Off Fretless/Wah at 36 If anyone else has some neat signature patches from artist I would love to see them.
