Thanks for the help. Just one more follow up….. I measured voltage on the adapter at 9.73 V, which I know is OK. I have no way to measure the amp draw. If I understand correctly, the heat is generated by the load, so that tells me the pedal draws close to the max capacity of the adapter. With that in mind, if I were to replace the adapter with another 9.6 V but rated at 250mA instead of 200mA, do you think that might help the heat situation ?. Could that hurt the pedal in any way ?.

Well, I followed your advice and plugged the adapter into the wall with nothing hanging off it, and it stayed cool. I also tried a BOSS adapter (9V 200mA) with the pedal and this one also got warm, but not as much. So do I have a bad pedal ?, drawing too much juice maybe ?….if so what do I do ?….return to where I bought it, or deal with EH directly ?………I must add that the pedal works great…..
