Pedalboard Inputs and Outputs

I am trying to compile ideas for input and output buffers for my "Deluxe" pedalboard. This has been capture by the Dr J Armor Booster/Buffer pedal above. Below are some candidates for buffers

• Emerson EM-Drive
• MXR MC-401 CAE Booster/Line Driver
• MXR Micro Amp
• Xotic RC Booster
• Xotic EP Booster
• Klon Buffer
• Cornish Buffer
• AMZ Jack Orman Buffer
• ZVEX Super Hard On with Volume Control

Another consideration is the effects loop. One of my requirements is to have a volume control to limit db's in my apartment lifestyle. For this I am considering the below.

• EWS subtle volume control
• Emerson EM-Drive
• Mad Professor Deep Blue Delay with Volume Control Mod
