Good speakers, even if the amp is terrible. The fish is mute, expressionless. The fish doesn't think because the fish knows everything. | |||

At the very least, yeah, Mark wound up with two nice vintage Celestions (assuming they’re in proper working order) and from the looks of the wiki, a decent long spring reverb tank if that’s one’s preference and the springs are in good shape. Like I said, looking forward to what you run into as you tear into it, Mark. The rebuild is most of the fun, after all.  ______________________________________________ “There are plenty of good reasons for fighting, but no good reason ever to hate without reservation, to imagine that God Almighty Himself hates with you, too.” | |||

Hmmm, I'm not sure if I like the Celestion Seventy 80 in the amp or the Celestion G12M. I'm leaning heavy toward the Seventy 80. | |||

They both sound good, but I like the beefier low mids and smoother highs with the G12M. The 70-80 sounds really scooped with a ton of highs and high mids. I bet they’d compliment each other nicely as a pair. Was that just a straight speaker swap A/B? A sounds like you’re running a lot more gain on it. ______________________________________________ “There are plenty of good reasons for fighting, but no good reason ever to hate without reservation, to imagine that God Almighty Himself hates with you, too.” | |||

Straight swap. No changes other than the speaker. The sensitivity is different between the speakers. The G12M is 96dB and the Seventy 80 is 98dB that's about 1.3 times the sound pressure level. I'm thinking in a band context the Seventy 80 won't get lost in the mix as much. | |||

I put a G12T-75 in my DSL40 and it sounds fantastic. When I have nothing better to do with the money, I'll try a Creamback, but no rush. | |||

I've got to remove some of the variables by actually putting one of the speakers in the Marshall combo. The separate open back cabinet probably isn't ideal. | |||

Don't you have a few different amps, mostly Marshalls? Wasn't it you that had loaned an old head to your brother or friend or something, back before you were looking at the Blackstar combos and such? In any case, I'd try the old Celestions with every amp at your disposal, since (I'm sure you know) every amp/speaker/cab combo can sound different. Last year I was at a friend of a friend's studio for a 12" guitar speaker shootout like we've all probably seen online or done ourselves. They had about a dozen 12s there that day, from old Celestions and Jensens to modern stuff from all the popular brands, plus about ten different heads and combos as power sources (Plexi head, vintage Twin, SHO head, etc). I left that day quite surprised by some of the combos that I ended up liking best. For instance, I preferred a newer Cannabis Rex (no jokes...) to a vintage Jensen in a reissue Tweed, which I would have never expected, and was blown away by a Marshall head that day with a particular Celestion and I'm not even normally a Marshall guy. I agree that your little combo sounds a bit better suited with its OEM speaker, but the vintage one does have a nice sound. Now it's just a matter of figuring out what amp it would better pair with, and perhaps whether or not it would sound better in a closed back cabinet or even a tuned and ported one made especially for that vintage speaker. Sometimes 1/10th more or less of a cubic foot of air volume in a cab can cause discernible shifts in tone/performance. | |||

Yeah that was me. I only have the Marshall DSL now. I liked it better than the Blackstar. I was the one that loaned my brother my 1972 Marshall Super Bass and he sold it. I've tuned the pedals and EQs to the OEM speaker so that could be why it sounds suited to the amp. I'm sure if I swapped in the other I could tweak it much more to my liking. I'm just concerned that since its a 40+ watt amp, I'd tear up a 25 watt speaker. I'd surely have to run two of the 25 watt speakers to play it safe. Edit - Oh, I forgot that there is a 20 watt switch on the back. Hmmm. | |||

Speaking strictly "ideally," yeah. That one's gonna punch and carry better. ______________________________________________ “There are plenty of good reasons for fighting, but no good reason ever to hate without reservation, to imagine that God Almighty Himself hates with you, too.” | |||

I just played through my DSL40C at full band volume with earplugs in for an hour. Sounded heavenly. But then I tried it at low volume without earplugs and it sounded like dog shit. No biggie. I practice unplugged or with an acoustic on the couch a few hours a week and then a few hours at full volume with earplugs through my big Marshalls before the neighbors get home. Might need to use an attenuator in the future. | |||

Damn shame about that head your brother sold.
Oh, that's no reason to worry, not really. There is almost zero chance of harm in sending "too much power" to a speaker. This is not how speakers get blown 99.99% of the time. At worst it could cause over-excursion/travel and maybe tear the surround or cone, but you'd have to beat the crap out of it and wholly ignore the warning signs to maybe even cause that repairable damage. Too little power, however, can create DC current in the voice coil and the voice coil essentially welds itself together which is what happens in most "blown speakers". One of the best things ever is to have surplus power on hand, or headroom as its often called. Contrary to popular belief, it isn't over powering speakers that's the risk, it's under powering them. So I wouldn't worry about that particular scenario. It's all but impossible, since you're no dummy and would notice the speaker flopping about via over-travel.... | |||

I took the GBX apart today and it's super clean inside and the solder work looks immaculate. Tons of electrolytic capacitors that I'll have to check for leakage. It's gonna be a project for sure. | |||

Great sounds at low volume have plagued guitarists for ages. Such a quest is the very reason your amp and 100 others like it in the Sub-50w range even exist, that mixed with the ever growing pool of Bedroom players who will rarely gig or play with bands, if ever... and that any of them truly sound good, like tracking/recording good, at low volume is amazing. Pretty much every famous guitar record ever was recorded at high volumes with big ass amps and multiple speakers, and these sounds and expectations are rooted in our very subconscious after so much exposure to it, but no one gets that sound out of a 40w 1x12. Not really. Even all the teeny low watt Fenders need to be cranked to sound like right. Sometimes it gets close, though, and maybe good enough, but there is always a loss. This problem is further complicated by the fact that the very lineage of Marshall amps in the first place is from taking high powered Fender Bassman head guts and hopping them up to be what we now call the Marshall sound. It's very conception is rooted in high volume and high gain and air movement and there's just no small/quiet substitute for it... | |||

Well, everything sounds better louder, for some technical reasons some much more experienced people than I have tried to explain to me. But the big thing is, the power tubes on tube amps don't start to open up and saturate nicely until they're pushed to some degree. So yeah, tube attenuators will get you there. ______________________________________________ “There are plenty of good reasons for fighting, but no good reason ever to hate without reservation, to imagine that God Almighty Himself hates with you, too.” | |||
