Concert-1 with electric bass
The Concert-1 works great for high output devices like active bass guitars. It is able to handle the huge signal levels from active pickups without distortion and the transformer isolation pevents ground loop hum. The Concert-1 sends the pure sound of the bass to the PA and to the player's amp.
Concert-1 with acoustic guitar
Acoustic guitars can sometimes have sharp sounding active preamps. The Concert-1 naturally smoothes out the transients for a warmer tone. And because the Concert-1 is able to handle loud signals from active pickups, it will not distort. This makes it a great direct box for acoustic guitars.
Concert-1 with a Keyboard
Today's digital keyboards are not only very dynamic, they also have a tremendous range from low to high notes. The Concert-1 is able to withstand excessive signal levels at all frequencies without introducing distortion or phase shift so all your patches sound great.
