I am currently thinking about changing the cap to activ, I had the SD 170 but want it integrated, currently I have build a power pedal into the head itself but the active cab would be even better. I would do a new back as well and I would look to get the wiring kit... if somebody has a plan which wires has to be connected it would be very useful... especially the large connector with the multiple pins. Anyway I will buy the icepower somewhen and then I will investigate, but if something exists it would be very nice.
on the J3 connector I had pins 6 and 7 tied together and going to ground/shield of the signal coming from the Kemper. Then pin 8 is connected to the hot signal from the Kemper. Those are the only 3 used from that connector.
