I run a Hartke HA 3500 head into a 4OHM Eden 4X10 cabinet. Ive been playing on it for a few weeks and recently it started smoking while playing (it seemed like the hartke was getting overheated). I immediatly turned it off. I use a Ibanez Prestige SDGR series and I think the pickups are active so I was running through the active input. I turned it back on running my bass through the passive input and it seemed to be running better and it much louder than when I I was running through the active input. Would it have anything to do with the fuse sled?
