Looking at the BOM for the After Blaster, there are no dip switches listed for this build. However there are 2 needed for the build. Are the ones listed for the “T-Drive” (https://guitarpcb.com/product/red-dip-switch-2-positions/) the ones I need for the “After Blaster”?
Actually you do not need two dip switches for the build. You may use a DPDT switch instead for a pedal mounted option. If you do opt for the 2 position switches those are indeed the ones you need and the ones that I carry. See page 2 of the Build Document and the schematic for dip switch. Also see Page 4 of the doc for the DPDT switch.
