Alright.. I just added to the SVT3 and 6x10 arsenal buy buying a SVT Classic and an 8x10 Cab. Whoa thats ****s heavy in more ways the one. A couple Questions for the crew here. Its got the old blue and red writing..is there an approx. date I can judge this amp on age with? Has anyone had biasing issues with this head? My buddy had it worked on a few times but I believe it was because he was a little rough on the road with it and gave the tubes hell. New tubes, full service and one gig later shes been going strong with me. Also has anyone gotten a roadcase for this head and do they have any idea on where I should start to protect this investment? Thanks for the help ahead of time and by the way I ran both 4 ohm ampeg cabs 6 and 8x10 at the last gig and it was rockin. I always wondered what the hype was about. Now to A and B my two heads at stage volume to really get a good idea on the volume and tone differences. Ive noticed at practice volume there isnt much difference but just that the classic sounds meatier. One last thing. I have a DBX 160 compressor..it does wonders for the SVT 3 should I even bother trying to work it with the classic or is that just wrong? oops no FX loop nevermind. Cheers!
