Thanks T2Stratman

No probs. I love all replies and I must admit I have for a thing for changing my amp back to original agin. However, a Master volume might prove handy when playing both harmonica and guitar both in a band and at home.

EriK, my guess is that the amp is the Twin Reverb AA270 circuit. The master was probably added to aid in recording and stage situations. JMHO Art

If you're happy with the tone of the amp as it stands right now then I would do absolutely nothing to jeopardize that sonic bliss beyond the routine servicing and maintenance that any piece of gear that old deserves. Forget the blackfacing bullshit posted by others who wouldn't know the difference between Kirchoff's law and a handkerchief and think bias is something to be legislated against at a Berkeley city council meeting.

:lol:

Bet that Twin had very good care and maintenance, in it's past. I too, would keep the amp as is. You know, there are very good master volume designs out there. My guess is that your's has one of these. Very nice amp!!! Art

Yeah! +++1 on Art's comment.

I have a 1968 Twin Reverb 2x12 85w Silverface. Normal volume controls.
This baby plays loud and clean. I still get good sounds/tones at low volumes.
But, I have to keep an eye on the volume, as it gets real "neighbor wake-up" loud.
To have real fun with my 1968, I bought a Weber Mass 200 attenuator
which acts like a MASTER VOLUME to keep the volume low, but still can play hard.


Even Better:
I have a 1984 Fender Twin Reverb 105w Paul Rivera Amp Head.
WITH MASTER VOLUME CONTROLS (and Gain and Presense and Reverb as well :shock: )
Gotta tell you, cranking this baby up to 6-8 and turning down the MASTER VOLUME,
is a real blast :!: :!: :!:

Like Art says, keep it unoriginal.
The original 1971's are cheap & available.
Hot Rod 1971s are few and far between.


Let us know what you end up doing. Take care. Toppscore 8)

Top, I also had a '68 Twin. Rebuilt(AB763) and put it in a Rodger's cream cab. Played it for years in the Blues band. I lavished so much attention on that amp, I called her the "Queen of Fullerton"! Art

You can have your speakers break-up at lower volumes with a Master Volume.


How is it that the speakers break up at lower volumes with a master volume control? I though that it was the tubes that create the breakup with a master volume control and that speakers only break up when driven to a high enough volume. I'm confused.

To the OP. You have a nice amp there that's been modded. You say you've been using it for 10 years and you have mentioned it's colorful history to us. I hope it's history grows well under your care.
Whatever you want to do with your amp I assure you that all the help you need will fall upon you from the fine members here. As you may have already seen you may get more than you expect for such a simple question as you have posted. Just wade through the pettiness and the sometimes long winded bragging about personal gear. Filter out the gems of information you need and try not to get sucked into the drama that happens around here at times.

I've been thinking about writing a book based on what I read on this site. I think I'll call it "When Egos Collide" :mrgreen:

You are not confused. You are 100% correct. Speaker breakup and power tube distortion require high power levels meaning the amp will be LOUD. A master volume allows you to crank up the first volume control and turn down the master to achieve preamp distortion at lower output levels. You will not get speaker breakup under those conditions. Preamp distortion sounds very different from power amp distortion due to the different mixture of harmonics present when one or the other overdrives. Turn both controls up all the way and the amp acts just like a non-master amp in that you get both preamp and power amp distortion along with speaker breakup.

+1000!

*SOMEBODY* flunked "tube amp theory 101".

1968's Fender amps are a very good year.
I have the:
1968 Fender Twin Reverb 85w 2x12 Silverface Drip Edge
1968 Fender Dual Showman Reverb TFL5000D 100w Amp Head Silverface Drip Edge
1968 Fender Bandmaster Reverb TFL5005D 40w Amp Head Silverface Drip Edge

I sold my 1968 Fender Bassman 50w Amp Head because it was missing the Reverb knob :lol: :lol: :lol:

Totally concur with the pre amp-power amp relationship, with a master volume. But I will say, that a well designed control will serve the user quite well. If power amp drive, in a Twin with JBL's is the goal, then Yeah, full power-on!!! JMO Art

Arc. You are right. I should have used the word "distortion". Sorry. IMO, the
master volume works similar to an attenuator, as far as end volume results.

Imagine taking a non-master-volume amp that has distortion
at #7 on the volume dial;
or, you just like the amp’s clean tones at #7 or #8.
Pretend #7 is the exact volume tone you desire for a song.
#7 on most amp's volume dials will get you kicked out
of most small clubs/bars and apartment complexes :lol: :lol: :lol:

Now, imagine all of the above to be true, but with an amp that ALSO has the
“master volume control” as well as the “regular channel volume control”.
With the master volume feature, you can set your regular channel’s volume
to #7 to get the distoration or desired high volume tone or sound.
But now, you can sustain the desired "high-volume-tone-sounds" and be able
to turn the over-all output volume "down" with the master volume,
or "way down" and onto "nearly barely hearing anything at all" :shock:

I own a ton of modern amps. Except for my Fender Supersonic,
I require all of my modern amps to have a headphone jack.
This solves a ton of problems as to when and how and where I play.

Also, I own a heavier ton of 1950s/1960s vintage amps which are both
combo & amp heads. They all range from 30w (1963 Tremolux) to 100w(+).
NONE are with MASTER VOLUME.

All of my 1950s-1960s Fender amps do not have master volume. I definitely must
watch out when and where I can play those babies, because of their raw power.

Until, last month . . . . .
Last month I purchased a Weber Mass 200 Attenuator w/Headphone Jack.
Headphone jack or not, the Mass 200 allows for me to play ALL of my vintage amps
cranked up to the desired amp volume output levels while using the Mass 200
to turn down the volume end speaker volume to zero or lightly minimal.
The Mass 200 with the special ordered headphone jack allows for play with amp heads
into my headphones WITHOUT A SPEAKER LOAD or NO SPEAKERS ATTACHED :!: :!: :!:
Is not that awesome :?: :?: :?:

Therefore, with the master volume on your 1971 TR (have not you had this amp for ten years?)
you can play great distorted tones/sounds at very low "bedroom" volume levels.



ABOUT ATTENUATORS . . . . .
I've studied attenuators for months. The Mass 200 automatically adjusts to any
amp's speaker impedance load or any amp's wattage & ohm output without adjusting
any Mass 200 controls :!: :!: :!: This is totally amazing. I questioned Weber many times
to make sure. Most all other attenuators are dedicated to only one wattage/ohm handshake,
or they may have a 2-4-8-16 ohm selection switch but no wattage potentiometers, variables
or wattage management at all. I own about ten vintage amps that all have different & varied
speaker/ohm and output transformer/wattage specifications.
The Mass 200 AUTOMATICALLY MATCHES ALL amp handshakes. Amazing :!: :!: :!:


You can use the Mass 200 when gigging.
The only issue with the Mass 200 and all attenuators, is you cannot dime-out the
volume and expect any attenuator’s impedance load to not swamp-out or burn-out.
The recommendations for most all attenuators is to have twice as much attenuator
than you have amp wattage. A 100w Fender Showman should use a 200w attenuator.
Try to keep the amp volumes into the attenuator at "8" or lower.

I really hope this helps you, your question and possibilities towards playing amps
with headphone jacks, master volume controls and/or attenuators.

Take care. Toppscore 8)
