04-06-2025I replaced the stock tubes on a Fender Pawn Shop Excelsior with these JJ tubes. Excellent upgrade in tone.

> 3 dayThese were given to me as a gift from a trusted fellow guitarist. It was a brand new matched pair and they kept blowing fuses (3 in a row) in my amp (Fender Excelsior, fixed bias). I put back my old Tung Sol 6V6’s, the problem went away. Brand new tubes and they already had a major short? Seems like a case of really poor QC. From what I hear these give more headroom than Tung Sols, but I couldn’t even get them to warm up.

> 3 dayA while back I got the book How to Hot Rod Your Fender Amp. In it, it says that the recent(90s and up)Fender Blues Deluxe and Hotrod Deluxe amps can be modded to take high power 6V6s made by JJ and Electro Harmonix. My stock Blues Deluxe amp was 40 watts and was running the tubes biased cold from the factory to make the tubes last a long time. The problem is running them cold makes the amp kind of sterile and unpushed. I had these installed and the amp biased correctly for them and my amp became much more touch sensitive at higher volumes. The Blues Deluxes preamp is based on a tweed Fender Bassman so to me I have a Bassman running into a Deluxe output stage. I changed the stock speaker to a Celestion Vintage 30 and the amp is much nicer on stage. These tubes have shown no signs of any problems; not glowing red or anything and I think it was a very good mod. Im guessing its about 22 watts now and is plenty loud for any indoor gig. The Celestion will handle 60 watts so should be safe from being blown out by the amps much lower wattage so I dont mind turning it up a little more.

Greater than one weekIve got a set of JJs that came in a 69 Princeton Reverb I bought online. They sounded harsh and bright in that amp. I put them into an Excelsior and they sound pretty good, still bright and hard sounding, but the Eminence Legend speaker turns that sound into a nice quack/chime. They are louder than Tung Sols, bigger sounding and more texture than the TS or the EH. They pale in comparison to a good set of RCAs in any amp Ive put them in. RCA is THE 6V6 to have, but these will do.
