Fluence Open Core Classic humbucker pickups now come in the popular uncovered humbucker style.

Using your Fishman Fluence Classic Humbucker Pickup Set is a breeze. First, you can simply drop the pickups into your guitar to replace the standard humbuckers. To switch between the different voices, you can set it up according to your preference and wire it to toggle easily.
If you choose to use the optional lithium - ion battery pack, make sure to charge it properly. The battery can give you weeks of playing time, but if you use the 9 - volt battery, you may need to replace it more often. Remember, the battery life can last up to 200 hours.
When it comes to maintenance, keep your pickups clean. You can use a soft cloth to wipe them gently. Avoid exposing them to extreme temperatures or moisture, as this can affect their performance. Also, if you're not using the pickups for a long time, it's a good idea to store them in a dry and cool place. Enjoy your new pickups and the great tones they produce!
