    Testimonial for Flever Sounds Japan Shop – Boss US-20 Purchase I had been searching for a reliable controller that could seamlessly switch between my Boss GP-10 and GR-55—or run them both simultaneously. After a long hunt, I finally found exactly what I needed: the Boss US-20, offered at a fantastic price by Flever Sounds Japan Shop. Most US-20 units I came across were listed at nearly double the price, so finding one in like-new condition at such a reasonable cost felt like striking gold. The

    Flever Sounds Japan Shop is a first rate seller. Not only did I receive the product in 5 days (which is very impressive considering it came from Japan to the east coast of the United States), but it was very carefully packaged in bubble wrap and a strong outer wrapper. It was in perfect condition. I would be very happy to purchase from this seller again. Much appreciated!

    Hello, I received the shipment in excellent condition, the goods were very well protected. The seller kept me updated on the status of the shipment, despite the fact that in Japan on 21-22.12.2024 was a holiday. Roland US-20 as described is new, orginally packaged and works in parallel when connected to Boss GM-800 and Boss SY-1000 synthesizers. The seller I highly recommend ! Best regards! Artur Nycz

    Playing 3-instruments at once using the Roland US-20

    The A/B and Both functions of this buffered switch box allow the instrument player to mix tones from two different synthesizers or choose one or the other synth. In my case I like the effect of being able to use the Nylon String patch on the BOSS-10 while simultaneously introducing a light Flute background patch from the GR-55. The switch on the BOTH setting achieves any mix of any two instruments simultaneously, and even a third could be added if the GK-3 is set to split the guitar input between the guitar's native pickups and the GK-3 divided pickup.T

    Roland US-20

    Roland US-20 does the job, all be it a little noisy when switching between 2 synth units. A bit overpriced compared to other aftermarket switchers. I'd Grade this a B- to a C+

  • Works very good but strange design on cable attachment

    Seems to be working well. One strange thing is the 13 pin cables go in upside down, meaning the push button to disconnect is on the bottom. None of my other devices - Gr-55, Sy-1000 or any of my GK guitars are set up this way. It’s very awkward to have to lift the unit in order to disconnect the cable. Probably should have been designed differently. Otherwise works fine.

  • a must for multiple GK equipped devices

    the us20 lets you use 2 roland guitar synths from one guitar... either or or both. really adds to the verstility, kinda expensive but worth it if you want to use more than one roland synth. works seamlessly. should include two 3 foot gk cords so make sure they're there, they're expensive to replace and the aftermarket 13 pin din cords work but aren't an exact match. the gk4p parallel box is similar, that gives one gk in to 4 gk outs. the us20 is more suited to live use with simpler setups.

  • Roland US-20 Must Have if Running 2 Synth Pedals

    If you are running two GR55s then you absolutely have to have a US-20. Very easy to use. This gives you the ability to really sound full with totally different sounds coming out of your Gr55s.
