I have a 66 bassman that has never been retubed and desperatly needs work. I am thinking about getting it up and running and using it for guitar and for recording. it has the original 2x12 cab with it wich also needs work. What would you guess I need to get done to it and how much would you guess it will run me? I am guessing the speakers need to be reconed or replaced wich would you suggest. I dont want to ruin the value of the amp but I dont see ever selling it as it was my grandfathers. Thanks for any info you can provide.
