The Fender Bassman 100T thread

Status
Not open for further replies.
I don't normally use the tuner out on an amp, preferring to go through a pedal in line to the amp. Last night I thought I would try the tuner out plug on my 100T and was surprised that it does not work when in standby - I cannot mute the amp to tune without turniung the volume down and losing that right spot on the volume control for the gig. Guess I am back to the in line pedal - am I wrong or does anyone else find this annoying? I assume it is the same with the tuner out on other brands too? Just does not seem much point to me. Haven't tried it with the amp's DI connected, I suppose the same applies.

I jumped on that tuner out right away. I personally don't like ANYTHING in line between my bass and the amp. IMO and IME, passing through anything when the signal is at such a low level and so sensitive to any added impedance, capacitance or inductance is asking for trouble, and results in a tone suck. That's why I still consider pedals to be toys. :hiding:
 
++1 on that, Freight Train, except that for years I have used a Sonic Research Turbo Tuner ST200 which is a fantastic strobe tuner with direct bypass - when I have tested it I have never been able to hear a difference. However, I will now be using the tuner out and the pull mute switch on the amp - although it is not quite as convenient as kicking a pedal in between songs to be honest my basses all stay on tune and it is only when I occasionally tune down to drop D that I need it. And no, I don't trust my ears over a tuner.
Interestingly your settings for overdrive with flats are very similar to what I have arrived at for my Jazz bass with its flats. I have been leaving the Precision at home recently and just using the 68 Jazz with the 100T, mostly on the vintage channel but that overdrive is far more useful than I ever thought it would be.
 
New tubes should arrive tomorrow - matched quartet of Winged C 6L6s. Being an impatient guy I shall swap out the preamp tubes with JJs at the same time so if what I have read is correct there should be a noticeable change ( I won't say improvement as I am very, very content with the tone as it is).
Will keep you posted and keep an open mind - more than happy to stick with the original Groove Tubes if ti doesn't work out.
 
ok question 1, if you were to run two 4 ohm cabs with the fender head , and you had one pluged into the main speaker and the other into the extension speaker jack, would you set the amp to 2 or 4 omhs?
question 2, is there any difference between hooking up two cabs as described above versus daisy chaining the cabs and running them from the main speaker jack at 2 ohms? thanks
 
Joemer, I am in New Zealand and don't know where you are but I had mine made by Sundown in Christchurch. For kiwis Dave is a great guy to deal with - PM me if you want his email address.
Growly, yes the amps are autobiasing which makes tube swapping a breeze.
Chrisan, it is my understanding that in both cases you would set the amp to 2 ohms.

Tim1, I am actually in the US. I'm sure I can find a cover maker. Played my first gig with the 100T last night and I couldn't believe the overall thickness of the sound. We played in a restaurant, in a fairly large area. We are 3 piece with a lead singer and I played at the 25 watt setting all night. Sounded great !

No difference, and in either case the setting would be 2 ohms.
 
For those who dig JJ Burnel from The Stranglers. I think I got close to his signature tone on the active side. P Bass with SS Rotosounds with pick: Gain 5, Blend 3, Bass 8, Vol 7, Mid Freq 8, Mid Level 8, Treble 7. It's not your everyday tone, but very aggressive with a lot of presence. You guys got anything cool?
:bassist:
 
My 100t was delivered on Thursday and I gigged with it last night for the first time and was very impressed. I may have a potential issue where I am seeing the 2 outer bias lights staying on steady orange. In the owners manual it mentions scenarios where any pair are red and orange but this is not what I am seeing. This has been an intermittent issue, that has happened twice. At all other times, all 4 lights have been steady green. Has anyone else experienced this?
 
na mine have always been solid green. i reread the manual and in the very bottom where it says all are steady orange with multiple tube failure there is a side note that says any pair will be orange if the fuse for those two are missing. im sure your fuse is not missing but maybe its bad? IDK. u see what im talkin in the manual?

Yes, I see that in the manual but if the fuse was bad I would think the pair would always be orange. I just tried it again and they are all back to green. I am going to have to watch it after playing for a longer period of time.

That can't be right - something's amiss. It might be good idea to take the cage off and make sure all of the tubes are seated nice and secure. Sometimes things rattle loose in shipment.

Took the back off, checked all fuses, tubes all secure, played for about 3 hrs today and all solid green. I wonder if a variation in house voltage could cause this? It never shut down or sounded any different.
