This is a new split stock water trap with a sponge device to collect extra moisture should you be a moist blower or be playing for long periods. It's very straight forward. With the split stock, you are able to remove the sponge and tube and either dry them off or replace the sponge. It may seem simple enough but it is very effective.
- This trap is the one at the bottom of the three shown in the photo - with yellow sponge
