The Fender Bassman 100T thread

I'm sticking with my Genz Benz Uber 410 103 db. Is that Fender cab sealed or ported?

I would think that's the perfect sensitivity for a 100 watt head. That's 7dB more efficient which is a way bunch. I think the Fender's ported but don't recall exactly. Pretty sure it would be. But again I shouldn't draw conclusions before I gig with it because 100 tube watts is considerably more effective power than SS. But all this comes full circle back to my worry about heat if the 100T is going to have to blow its guts out with an 8 ohm inefficient 410. It also makes me wonder if this is why the 410's are so scarce. Could be Fender's found nothing less than 6 drivers is going to be adequate in an inefficient cab with the 100T.
Holy crap I'm starting to sound like a Kennedy assassination conspiracy theorist! I'm just going to take a deep breath and have a Jack rocks and jam a little.

I still had the three cabinets setup in my band room from an amp comparison at the weekend, so have just done a test on this. Please bear in mind that it is not scientific and is based on my hearing and perceprion. I had the Bergantino NV610 (sensitivity 103 db), the Bergantino NV215 (101 db) and the Fender neo 610 side by side. I used the vintage side and had all tone controls at 6 (thanks Freight Train :) )and the gain and master volumes both at five. The Fender 610 was definitely louder than the NV215 which had a more open sound; the Fender 610 was about the same volume as the NV610 which had a tighter bass but the Fender bin had a little more bottom end being ported. I had the tweeter on the Fender set in the middle, but the result was the same in the NV610 comparison with it off also. I used my 1968 Fender Jazz bass with both pickups on full. The results are obviously open to interpretation but certainly put my mind at rest.
Then for the hell of it I cranked the Fender stack and I really cannot imagine too many situations where the 100T wouldn't be plenty - again I say that it just seems to have so much more headroom than my old tube Bassman 100s and 135.

My fender 610 pro and 215 pro are both much louder than my Bergs with the 100t. They are the non neo fender cabs. By contrast the Bergs seem a little muffled and like they havent opened up yet.

Yes, I certainly agree that the Fender neo cabs seem at least as loud as the Bergs and the Berg 610 has 103 db sensitivity. I do not think there is any issue at all with the sensitivity of the Fender cabs for the 100T head - they seem a great match. The Berg 215 certainly sounded more transparent to me but it does have the 6" midrange driver but I thought the Fender 610 had more bottom end. I agree the Fender 610 is more open sounding than the Berg610 which I sort of expected since the Berg does not have a tweeter. Either way Fender have got it right - their head and cab not only look great together but sound great together.

I continue to learn in this thread. Can you explain the impedance difference with tubes compared to SS?
Click to expand...

Not getting bogged down in details, but the way the output stage of SS amps works, they can safely drive a range of impedances - usually anything from 4 to 16 ohms, but the amount of power they'll produce is directly affected by the speaker impedance. So a SS amp that'll deliver 300 watts into a 4 ohm cab will be something in the 150 watt range into 8 ohms. Tube amps on the other hand have to be carefully matched to the impedance of the speaker - that's the impedance switch on the 100T - and they'll deliver the same power to any of the impedances they're rated for. So your 100T will deliver 100 watts to an 8 ohm cab the same as it would a 2 ohm rig.

I use to live in Witicha Falls area for about 15 years that is about 150 North of Dallas but now now live in Florida. Where in Dallas did you purchase you Fender Bassman 100T and Cabinet, can't find them here in Florida?

Thanks

Seems like I'm always the cock blocker around here. I'm not trying to dampen spirits, but as I keep pointing out this is all brand new stuff and new technology, we're in uncharted waters and believe me we first guys in are more or less the beta testers for Fender. I would be shocked if they have made the cabs too inefficient for the a single 410 neo to be enough cab for the 100T, but it's not beyond possible. And from decades of experience I know manufacturers will sometimes rush things out before they're fully beta tested in order to make the next big trade show. Don't really think Fender would do that with this series as it seems nothing but top-of-the-line to me, but again it's happened to manufacturers bigger than Fender. If you want to live on the bleeding edge by being among the first to buy into something, you have to accept the fact that some unforeseen bugs might be popping up.
The test I did was with a 1kHz tone and a sound pressure level meter carefully positioned to be at the same distance with both cabs. So we get to the old thing of testing with tones rather than program, but it is a valid test and repeatable.
I wouldn't be going through all of this if I didn't totally love what Fender is doing here. I'd just get something that's tried and true. I'm just overly anxious as all of this happened just as I am getting a new band together, so I haven't been able to get it into a real gigging situation yet and see what it can really do. I don't care what it can do in the practice room or rehearsal, I gotta know if it's enough for a medium sized club venue with no mains help and the style that I play, which you might say is not shy. May 18 will be that day for me. Believe it or not, I'm expecting good things.

Hey man! Small world! I'm from Nocona, Texas, which is the little hick town with the boot factory about 45 miles east of WF, but moved to Dallas right out of high school in '71.
I got the head from Sweetwater. I don't why it worked this way, but for over a week the only place I could find anywhere that had a 410 neo in stock was Austin Bazaar in Austin, and every time I looked it showed they only had one. So since Sweetwater wasn't coming anywhere close to getting one, I just called Austin Bazaar, thinking there's no way they had one and they probably just didn't keep their website updated on quantities. Turned out they not only had that one still in the warehouse, it was unopened. Ordered it last Tuesday, got it on Wednesday. Plus, being an established studio pro here in Texas, I got it for a much better deal than what you see online. Could've done the same on the head if I'd known.

Take off the Engineer Hat, put on the Musician Hat & wait & see! :) Don't kill it on paper before you use it in the real world. (still, all your measurements and concerns are entirely valid!)
