Using this EMG push/pull potentiometer is easy. First, choose the right shaft length for your guitar - short for Strat and long for Les Paul. Then, connect it to your dual - mode pickups such as 89 or 81TW. Since it's solderless, you don't need to deal with soldering equipment. When handling, be gentle to avoid damaging the potentiometer. For maintenance, keep it clean and dry. If you notice any issues, check the connections first. This potentiometer will enhance your guitar's performance and give you more sound options.
