Impedance matcher?

[smeet]

So I play active basses and I love them. But some effects don’t deal well with the signal. In many cases this seems to be due to an impedance mismatch. Is there a pedal or box that will let me dial my impedance up or down so the finicky pedal will think it sees a passive bass signal?

This one should do what you are looking for. You’d have to import it from Greece though, so maybe someone else knows a us made product.
