I've had a 2204 for a long time that came with 6550's. Was considering trying out EL 34's. It doesn't seem like too involved a swap. Just wondering what people think. Is it worth doing? Easy to reverse?
I'm actually cab shopping. Had been using a 70's Ampeg 4X12, but I've also used the amp with a bunch of different Marshall 4X12's over the years.What speakers are you using?
You may want to try different cabs/speakers before anything else, pretty easy first step instead of having the amp rebiased etc
I believe Cesar Diaz said Hendrix used 6550’s in his Marshalls for the bass response
