It does what it is supposed to do, BUT the signal loss is really notable. My Moog Grandmother had a loss of -6dBs when going through it, which I guess could be acceptable, but then my Roland TR8 had a much bigger loss of around 18dbs. I guess you need an active device in order not to lose volume, but I wanted to leave this here because some other user commented that the signal loss is almost inexistent, and that was not the case with my setup.
