About this product

Product Information

Guitarists who use multiple pedals, tuners, and metronomes can go through 9-volt batteries quickly. Instead, try a PSA-120S power adapter from Boss. This Boss AC adapter has a 10-foot cord. It can easily reach your nearest wall socket or power strip. It is compatible with Boss mini and twin pedals in the ME-50/-20/-20B series. It also works with DB-66/-88/-90 multi-effects. Save yourself the hassle of dealing with 9-volt batteries for your Boss effects pedals.

    Works for Boss products

    The Boss PSA wall adapter is the best adapter for your pedals. I have used others such as Power Spot and although they may work, Boss does not recommend them. I believe this is due to the warranty issues. The PSA does not block other outlets if you're using a power strip. There is a green indicator light so that you know it is working. Other adapters I have used have, over time, developed a "hum" or they are susceptible to interference from fluorescent lights. Maybe I'm just a stickler for the rules, but I use a lot of Boss products, so I like to "keep it in the family".

    easy to use and works great

    Got this to power up my BOSS Micro BR recorder and now I don't have to keep buying AA's every other days. No cons works great.

    PSA 120S

    I didn't try recording electric wired guitars with my boss br864,but I'm looking forward to it. Since the boss br864 has digital amplifiers in it, using the PSA 120S addapter may reduce the cable distorted sound,I heard a rumor about it and I hope it will.

    Good buy

    I've tried to use the cheap ones, but they just don't work. I've only had one of these fail out of about 10 that I've bought in the last few years. Takes away the noise for guitar pedals.

    The best 9v power supply.

    Simply the best 9v power supply on the market for powering up guitar/bass effects pedals. Very quiet noise floor and reliable for many years of use. Not the cheapest power supply on the market.But it's the best and well worth the money.
