    I usually just try stuff. Not sure if I should this time.

    Traded into a really sweet '68 SFDR. Came to me with one of the original Alltone 1250s installed. And it does sound really good. A few pre-amp tube changes later, even better. The surprise is, it's noticeably better than the (also excellent) '67 BFDR I had for years. In which I tried many speakers.

    I just got a deal on an Emi GB128. Have used this speaker in other cabs, combos, and have always enjoyed it. Question is, should I go to the trouble of swapping it in to try in the '68 DR? Has anyone had experience with both speakers in a DR?

    I'm curious, but not sure I could improve on the Alltone. Thanks much!

    When I bought a GB128 I thought it was the same speaker as the Alltone 1250. I tried them both in same cab with a Princeton Reverb, a SCXD and my 6V6 Plexi and they were so similar (allowing for the Alltone being broken in) that I set the Eminence aside for a rainy day (couldn't return it, long story). I currently have the Alltone in a 1x12 cab with my SCXD plugged in most of the time - puts out a great Fender tone. Neither that amp or the speaker has ever sounded better. So I guess what I'm saying is - sure go ahead and try the GB! What's a liitle time spent?

    I have had many but not the Alltone. Reportedly they were pretty sweet. I tried various brits in my DR; GB's, Cremeback, various G12-65 types. They were not my favorites. Although Robben Ford reportedly uses a G12-65 in his DR.

    I have not tried an Alltone 1250, but I can attest to the fact that the Eminence GB128 is a great greenback-style-ish speaker in a SF DR. If you don't mind, why don't you put it in and give it a listen? Then do us the favor of reporting your findings. I'd love to hear what you think about the similarities and differences, and what you prefer.

    Alltones are very good speakers . I had a 1045 in a NR Princeton once and it blew my bandmate’s 70’s PR outta the water both tonally and volume-wise. He had a Celestion Vintage 10 in his.

    That's exactly what I usually do, just try what I have and see. The Alltone is soldered in, which makes it just a little trickier. I don't have a lot of energy these days, so that's part of the reluctance. But you're right. I should get the little press on connectors to make swaps easier, and just do it. Then report back of course ...

    A few hours later ...

    Thanks for the nudge Professor. Once I got my dead ass in gear, it was no big deal. Especially as I found a spare speaker wire harness on the parts shelf. I used two teles, one with regular single coils (Don Mare Joel Foy set), the other with 2 P90s. Left both guitars set at a certain volume and tone level. Same went for the amp. Volume 4, treble 6, bass 4.5.

    GB128: At 102db spl I figured it would be quite a bit louder than the Alltone. Louder yes, but not by much. Very even balance low to high. Nothing really pops out. The low end is not more prominent, so much as it is a bit more defined, or detailed, than the Alltone. This speaker sounded quite good. I could be happy with it in this DR. Except that it had a somewhat harder sound, for lack of a better description. Maybe the bigger, heavier magnet? Not sure why. I didn't test at higher volumes, but would certainly expect this speaker to break up a bit later than the Alltone.

    Alltone 1250: 98db spl, yet it was only a bit quieter than the GB128. The key difference with this speaker is the warmth. It has a little bit extra in the mids. Not a prominent spike as in some of the Brit voiced speakers. Just enough extra fat that it fills in that BF/SF scoop a bit. I don't mean "warm" as in less bright. Both speakers seem equivalent in brightness. Just that the Alltone has a smoother, warmer edge as the volume goes up. Doesn't have a hardness to the sound. More pleasing to the ear. This speaker too is well balanced. Not lacking in bass, matches up well with the high end.

    Not any kind of rigorous test at all. I wouldn't generalize from this experience. At least with this SFDR, the Alltone is the clear winner. It's back in now and won't be coming out. Too good to mess with further.

    Just remembered that some years ago I tested my Alltone in a DRRI against a couple others and recorded it. I think the others were the C12K original and a hi-power Weber Chicago. I remember the Alltone sounded pretty scooped & clean while the Weber was much more middy but also fizzy even at clean volumes - it was just reconed by Weber from a Thames (which was horrible) so no break-in time. Those soundclips exist somewhere, I hope to dig 'em up.

    I had an original Alltone 12" in a 1968/69 SF DR years ago, I had tried a lot of different speakers in that amp,IME the Alltone was the best sounding. They started making them again I think but I've read that the newer Alltone speakers sound different.
    I tried an Eminence GB128 some time later in a different DR, it was good but different to my ears.

    Thanks for the report, mad dog! Sounds like the Alltone 1250 is a winner!

    I have a GB128 in my 1972 Silverface Deluxe Reverb. Love it! All the clean you expect, and anything over 5 on the volume is magic, really growls when you hit it.

    GB128 is my favorite speaker.

    I love my GB128 along with a Cannabis Rex in my 2x12 50 watt Kendrick combo.

    Alltone 1040s in my VR for the past couple years. Excellent speakers. Retain Fender clarity when clean, sweet breakup when pushed.

    Love the GB for all amps I've used it in. It does have the British upper mid thing going on which moves it away from the traditional relaxed upper mid Fender tone. Nonetheless a great sound with nice muscle for stage work.

    We must hear things differently.
    To my ears it lacks the upper mid thing of a e.g. the new celestion V-type or a celestion classicl lead 80,, It is woody with lots of low mids,, Just listen to a demo on youtube with a guy comparing 4 celestion and the GB128 in a twin reverb.. THe four celestions in the test, Classic lead 80, Celestion 70/80, V-type and G12K, all have clarity as having more 1-2kHz signal and more above 3kHz than the Eminence which has a larger dip at 1.5kHz and less treble above 3kHz.
    Right now I have paired the GB128 in a large open back cab with a solid state DV mark micro 50 amp,, The mid control on this amp has a low center frequency,, (no harsh mids when boosted), The problem when playing with the band is that the amp/speaker lacks high mids to hear myself in the mix.. The celestion 70/80 with this amp seems louder as it cuts through with a large 1.7kHz spike.. A spike that is rather annoying in amps that have a lot of high mids in the signal.. I can see why the GB128 speaker works nice in a fender blues juniior,, The small open back cab and the more biting nature of the tonestack (not a fender blackface tonestack), and pushing the EL84 output stage in that amp fits the GB128 to a tee.. But the sounds of the DV mark micro 50 is big and warm with a mid knob with a low frequency center.The GB128 likes the slightly overdriven nature of a small EL84 amp as it introduces second an third order harmonic distortion.. Play an A4 at 440Hz and you get an extra 880Hz and 1760Hz signal added when the amp distorts slightly..

    I have found the gb128 to work well in any amp, seems to give an even string response, with tight bass.
    I played through an amp with an alltone years ago and remember it sounded good.

    I have a stereo 4X12 cab, with a pair of the Alltones in the right hand side, and a WGS Green Beret (greenback clone) and Emi Texas Heat (greenback w/bigger voice coil clone) in the left hand side.

    I can basically A/B the right vs. left hand sides of this cab in just about real time, and what I hear from the Alltones is a more scooped sound, and when the amp is overdriven, they sound more bright and brash, compared to the greenback'ish speakers.

    If I want a fatter sound that handles overdrive more musically (to my ears), I'd go with a speaker that's supposed to be more of a chapter-and-verse greenback clone. If I want something where I'm going to use the amp for mostly clean stuff, or maybe with an amp where it's harder to eke more top end out of it, I'd go with the Alltone.

    Just IME.

    +1 on this review of the two speakers. This was my experience trying both. I still have the Alltone but sold the GB128.

    Another original Alltone 1250 fan here. I have two. One is in my ‘72 SFDR and the other is paired with a ‘56 Maggie ‘p232’ in a convertible open back 2x12. When running the SFDR, I’ll often plug in a ‘60 Jensen P12 that’s in a tweed Avatar 1 x12 cab, kind of getting the best of both ceramic crunch and alnico compression.

    I’ve never tried a gb128, but have tried a dozen other new and vintage speaks in that SFDR (including the original Utah, yuk), and the Alltone just wins.
