That amp sounds killer.Oblivion DC":13pfylbg said:BrentSSL":13pfylbg said:Oblivion what's changing the tubes like on a framus? Is it simple like a rectifier or do I need to bias them every time
You need to bias them - but the Cobra has bias test points at the back of the amp as well as an adjustment port. Get a multimeter and set it for volts. It'll give you a fairly accurate reading. You will need to know the plate voltage in order to set the bias but once you learn what it is you won't need to open the amp up again.
EDIT: Not sure what kind of sound you're going for but this is a room recording of my old Cobra. Just some noodling, testing levels and feedback, nothing special.

Yeah man, that's right. It's was only a little modded I think I had a choke put in and a slight reduction in the gain and had it set to run KT88s. I was using a Bare Knuckle Aftermath in the bridge of an ESP Alexi "Scythe". I liked how raw it sounded but I was having a hard time getting the loop to behave.
I'll definitely get another one in the future but I'll probably leave it stock.
