Hey guys. I have a SWR Workingman's 4004 head with a SWR Workingman's 4x10T cab and i was wondering if it would be stupid to get a tube preamp for my rig. I know the rig needs a little more warmth and was wondering if the tube preamp would do the trick or if i need a power amp to pull that off. I'm an intermediate player but i just got the rig so i don't know a lot about the whole amp thing. Or would it just be worth it to start over and get a tube ampeg rig or something?
