Welcome to the Fender Twin Tweed Project builder site.

The purpose of this website is to document my progress as I build a late 50’s Fender Twin Tweed (5F8A) guitar amplifier.

Also, I look forward to comments from other amplifier builders; in attempt to further my knowledge base throughout the process.

Hopefully, others will be able to utilize the information on this website to assist them with their projects.

  1. Hi, I just found this site and I am extremely interested in following your project. It appears that there has been no site activity since 2010 though so I thought I’d sign in, express my interest and ask how’s it going?
