Fender Bassman 100T - chapter 2

Status
Not open for further replies.
Bass Gear Magazine scoped the Super Bassman, which uses the same preamp, and got 1-10-1 as flat.

Cheers,
Liam

Yup. Link Removed. On the Super Bassman, at least, the Vintage channel EQ definitely seemed to respond like the classic Fender tone stack, and what my ears told me matched up with what Tom Lees measured. I suppose it's possible that the 100T is set up differently, but I didn't think it was supposed to be any different from the Super Bassman.

Edit: I was going to add that the optimally flat setting on the Overdrive channel was not too far off of the center detents, but it looks like Liam already covered that.

I totally dont doubt you guys but it makes me wonder why Fender calls it a cut only eq in the vintage channel in the manual. You would hope that they know what they are building.
 
Its really a 1 band midrange cut only eq. The 3 knobs control the parameters that shape the curve. The 100T EQ is very subtle compared to other versions like the alembic, so 1 vs 2 isnt going to change a lot.
 
Lord! To hear someone say the 100T/410 Neo won't cut through with a loud band with no P.A. support is like the people telling me sex only burns 4 calories a minute. Clearly, you're doing it wrong. By my count, played my 32nd gig with the rig Saturday night, and the thing blew the walls. Had a well respected bass player in town come up and tell me my sound was "insane". Once again, never been happier with a rig in 47 years of playing.

It did cut through, though not very well in the upper registers after I adjusted the mids. Then it got much better. The headroom was not as generous as I am used to however. Like it said, nice amp, but no SVT or v4b when it comes to raw power.
 
I assume the answer is yes, but would this thing be way overkill for playing at home? I love the idea of the vintage tone circuit and being able to use it in 25watt mode. I don't play out much at the moment so this is way more amp than I need, but I can't help but want one. How's the tone at low volumes on the 25watt setting? Good mic'd tone for recording?

I went through a lot of Class D amps trying to find one I like for home/studio use and finally gave up relying on the reviews to sway me. But knowing what a true tube amp could do and the honest discussion by many 100T owners here I took the plunge. Great, great amp!! A sure keeper.

I only use it at home and in the studio at the moment and 25W is more than I'll ever need. I change it every now in then to get the grunt of 100W but the 25W is substantial - way better than the Ashdown Little Bastard 30W.

If anyone is reading these post on the fence this amp is phenomenal if you want a "portable" tube amp. Granted it's not an SVT and many people seem to too think it will duplicate or "it's" supposed to be a small SVT but it's not - it's a "Fender Bassman". And it sounds like a damn good Bassman. I have both and they're both great amps.

So glad my Class D quest is over - I was trying so hard to make them something they could never be - but the Bassman delivers.
 
Its actually very loud for home on 25w. Im selling a 25w power soak for cheap that you could use to dial it back while letting the tubes do dome work. I swapped down to a 5w tube amp for home and its still pretty loud.
 
Looking to downgrade my rig to two heads, maybe you all can help with the decision.


Fender Bassman 100T, to cover 99% of shows, and use the 25W switch for studio and home stuff.

Genz Streamliner, for when I don't want to carry a tube head. If (for whatever reason) the Bassman isn't loud enough. I can run preamp out of the Fender, into the Genz's poweramp. May not sound the same, but at those volumes, I don't notice anything.

What do all of you think?

Dont think you'll need the Genz.
 
Those are my main two. The 100T is seeing the vast majority of gig action, but I'm using the Streamliner sometimes during practice at home and to have as a backup. (You never know.)

Sounds like a good idea to me. Keep in mind you the pre out from the 100t is post-power amp, so you get the power-amp tube-breakup tone. That, and you can run it without a speaker load. The 100t is very versatile!
 
The owners manual indicates that you can connect a 4 ohm load to the main speaker output and an 8 ohm load to the extension speaker output, resulting in a total load of 2.6 ohms. It also indicates that to do this your amp should be set at the 4 ohm setting.

I usually don't like running fractional impedance loads, but apparently this amp provides for that. This is the only combination of different speaker impedance loads that is indicated in the owner's manual to be acceptable.

And if I load the 8 ohms cabinet to the main speaker, and the 4 ohms to the extension? Can this combination cause some damage to the amp?
 
Well if you take a look at your owner's manual, they are very specific as to what goes where. It is on page 7, item "S". Most manufacturers don't recommend mixing cabinet impedance loads at all, so I am actually surprised that this amp even tolerates it. IMO You should stick to what fender recommends.
