Do the Nova pedals have analog-dry-through?
Unlike TonePrint pedals, there is neither true bypass, nor analog dry-through in the Nova pedals. They are built on the G-System and G-Major-2 concepts, with a permanent AD/DA conversion, for the entire signal.
This said, Nova pedals converters are extremely transparent. (just like in G-System and G-Major 2) and will work perfectly in any amp's serial FX loop.
