What I am working on . .
1960’s VOX AC30 original chassis in a modern reissue cabinet. This one had the top boost added some time back but the owner felt it was just a little too brash. So let’s remove and try it without. It’s quite an easy job to install and remove the top boost as there are just a … Read more
