I'm going with a "Fat Jimmy" C1025 for my "just started to be built" Tramp. These speakers are designed to work great with vintage Fender amps. I have a Fat Jimmy C1270 for my 1969 Fender Bassman 50W head. The owner of Vintage Fender Amp Repair in California designed them and Warehouse speakers builds them.
https://vintagefenderamprepair.com/prod ... 8451140301C1025: Our favourite 10″ speaker. Rated at 25 watts, this 10″ speaker has a certain magical quality to it. It delivers everything you could want in a 10″ speaker – punchy lows, richly textured mids, and smooth, round highs. As a single speaker it adds just the right amount of speaker breakup to your sound when pushed, without losing the tight ‘clean’ characteristics you need for optinal performance, even at higher volumes. This speaker has the smoothest, creamiest overdrive characteristics of any speaker in the FJVS lineup (which is saying quite a bit). An incredible upgrade for a Princeton Reverb or any vintage Fender with 1 x 10″ speaker! Highly recommended as a full replacement set in any 4 x 10″ combo such as a Super Reverb or Tweed Bassman, or any 2 x 10″ combo such as a Vibrolux Reverb, Brown Super, Tweed Super, etc. MAGIC in Tweed circuits (does wonders for a tweed Vibrolux)!! This setup will also help your 4 x 10″ or 2 x 10″ combo shed some serious weight! Rated for 25w.
