Double Bass FDeck HPF-Pre?

[drurb]

If you run your bass into the preamp, and then into your FX return, then you retain the 10 Megs. If you run the preamp through the effects loop, and use the regular input of your amp, then you get whatever impedance your amp has. I think Ric might have meant the latter. Still, it's worth finding out what impedance your amp has, because many of the newer amps sold for DB use have sufficient input impedance.

Ric did mean the latter.
