The Deluxe pedals for bass like the Bass Big Muff Deluxe and Battalion are really great. The one problem is, I wish that there was an effects loop for these pedals. In the case of the Battalion, an effects loop after the compressor and gate, but before the drive would be perfect. Of course the loop being before the DI output is also important. I like to run the Bass Clone and Holy Grail on my bass, but after compression/gate and before drive.
To potentially make it even better, a separate foot switch for the FX loop. In my opinion, this would make pedals like these absolutely perfect.
