Walrus Audio Canvas Nano Line Isolator
I use it to go to a PA from a Tonex peda, which also goes to my guitar amp and cab. The signal it produces is strong and clear better than a DI box.
The size is great and doesn't take up much room on a pedal board.
Great that it doesn't need power.
Feels well made and sturdy.
A few less features than the larger one but not a problem.
I use it in a live environment and it's a great help not having to mic my guitar cab, makes the overall sound better.
