Boss PSA-230 Regulated Power Supply

The Boss PSA-230 AC/DC regulated power supply (PSU) is perfect for most Boss guitar and bass guitar effects pedals, stomp boxes and for some other Roland and Boss products. The PSA230 power supply output is regulated and smoothed, which means that the voltage and current delivery are constant and almost no hum is produced. A regulated DC power supply with very low hum is essential when using guitar effects pedals, especially distortion pedals. Humbucker pick-ups reduce hum – hence the name – while single coil pick-ups are more prone to hum. To reduce hum, especially when using distortion pedals, try switching to the humbucker pick-up if your guitar has one, or switch to two single coil pick-ups combined if your guitar has single coils. An example of a humbucker guitar is the Gibson Les Paul and a single coil guitar is the Fender Stratocaster. Most Boss guitar effects pedals only require a small current, so several pedals can be used with only one Boss power supply unit (PSU).
