Hi all, I have marshall sv20h, but the amp is very clean and i am looking for some more dirt and blues sound. Now i need some advice for what fit my needs best. Vox ac30 Fender bassbreaker 45 - master volume Fender bassman 70 - master volume Fender bassman 50 1969 - no master volume. This would be with attenuator. I am looking for some eric clapton/rory gallagher/srv sound. Who can give me some advice? Thanks in advance!
