There are 3 ways you can buffer your signal. The first is with active pickups or circuitry. Active pickups take a weak signal and amplify them with a preamp and a buffer. Active circuitry works the same way, by boosting frequencies and buffering the signal. If you run active circuitry on your bass, your signal comes out buffered. The other ways to buffer are with pedals. You can either run buffered pedals, or run all true bypass pedals and have a dedicated buffer. If you have a passive bass, and use long cable runs or multiple effects (or both like me), you need a buffer in your chain to prevent signal loss. Some people use pedals with weak buffers (Boss) and stack them to buffer their signal, but this tends to weaken attack response. The best way to buffer with pedals is to use all true bypass pedals and have one, strong, dedicated buffer. So, how do you buffer your signal?
