Well i've been searching for the perfect bass amp for quite awhile and haven't found anything thats just right yet. So I thought i might give a shot at building my own. It would be class A tube so no circuit boards or anything, and it would have the most basic controls. I figure how tough can it be? anyways, im looking for some info on schematics, tube manufacters, pots manufacters and whatever else might be helpful, any info would be greatly appreciated.
