I am trying to run my HD400 through as an effects loop into my VHT GP3 preamp. I have it setup in the following order.
VHT fx send -> to HD400 fx return
HD400 fx send -> sent to VHT fx return
both mono channel
I program the bank on the hd400 to turn on the effects loop and the mix is set at 100%
my guitar input is going into the VHT.
The VHT channels come through just not the HD400 fx.
why is this not working?
thanks.
Ken
