The Texas Red model uses the Celestion Vintage 30 speaker.
The V30 is known for its strong midrange and is well suited for classic rock/lead guitar.
Here's what I did to mine to make it 'better': - replaced the stock speaker with a Jensen Neo 12-100 - replaced V1 tube with a 12AY7 (that pretty much solved the volume-issue and the bass-heavyness - reflowed all solder joints - replaced input jacks - placed tilt back legs on it - most don't like the drive channel (I think it's ok as long as you keep gain settings low) If you don't want to solder: buy the reissue!
Don't be put off by the Made in Mexico instead of made in USA. ) The seller is asking 0 as he is trying to present it as a "Vintage" amp.
There is a poll going now in which the Fender Blues Deluxe is mentioned as a choice for the best Jazz Amp. There is one on Craigslist near me and I was thinking about checking it out this weekend. Any information on the headroom and voicing for this amp would be appreciated. Pro's: - good sound, that leans towards the old Tweed Fenders, but can also do Blackface type of sounds - real spring reverb - more than enough clean headroom for jazz applications - not as heavy as a Twin - can do pop, soul & rock as well - reacts very well to pedals - not too expensive Con's: - still a rather heavy amp - reverb is not tube-driven, but IC-driven, which sounds not as good to some - can be bass-heavy with archtops - stock speaker lacks a bit when things get louder (read: at volume levels un-typical for jazz) - does a lot very well, but does not excel in anything - volume pot is a log pot, so volume jumps from zero to too loud very quickly - the original series had reliability issues!
(broken solder joints, crappy input jacks) The reissues have that fixed, btw.
Stock Speakers Outside the chassis, Fender has used several different speakers in some Blues Junior models.
All green boards and all black Tolex BJrs use the Fender Special Design, which is built by Eminence and is equivalent to the Eminence Legend 125.
Other cabinet coverings include blond Tolex, dark brown Tolex with a wheat-colored grille (custom for a Canadian music store chain), and the Texas Red Tolex.
The cream-colored board is laid out entirely differently (and better) than the green board. But the old ones sound darker, while the new ones are brighter, with more emphasis on treble tones.
