Maybe this will help https://www.fmicassets.com/Damroot/Original/10001/OM_leg_gtramp_Super_Twin_Reverb_1977.PDF
“Equalization and Harmonic Balance Controls†- that’s a mouthful. You could probably think of it as a graphic equalizer, where the “0†setting on the control knob is flat, the numbers to the left represent a cut to the indicated frequency, and the numbers to the right boost it. So, set your normal tone controls where you get close to the sound you want, then fiddle with the EQ knobs. Looks like the frequency range of the EQ section stays mainly in the medium low to upper mid range. Use the presence knob to fine tune your treble setting. |

That's one Professor Weirdo model of amp. If clean is what you want, you got the right amp. Heavy enough to anchor a battleship!
You have your hands full. The "harmonic section" is control over specific frequencies:
2300KHz- Guitar string mid range
1250KHz- Guitar string mid range
485Hz- Lower mids
235Hz- Lower mids
100Hz- Upper bass
Since the knob has a "0" at the 12 o'clock position that means the frequency can be attenuated (cut) or boosted.
And since there is a foot switch option to turn this section on and off, it could be used to kick in this harmonic section during a solo so in effect it's like a two channel amp so to speak as you have the option to switch in a different EQ setting at the flick of a switch.
As Fred alluded to a "graphic EQ" he's right except these are knobs not sliders.
The above photo does not show ALL the exact frequencies. The human hearing is 20Hz-20Khz. So it is impossible to create a physical EQ device that covers 20,000 frequencies. It's basically ballpark frequencies used for the instrument which happens to be guitar in this case.
You would need to sit down and practice using the amp and training your ear.
It's not an amp for the uninitiated as to using expanded equalization parameters. Each slight turn of the harmonic section will dial in thousands of possible combinations.
Then you have the basic EQ section to the left of the harmonic section. You would have to experiment by switching in the harmonic section to see if the basic section is still in the circuit and works by trying to move the knobs of the basic section. If both EQ circuits are on together then whatever you dialed in in the basic section may affect what the harmonic sections settings are.
I don't have this amp and never used one. The manual does not say.
You may have to plug in a foot switch to get the harmonic section to activate. The foot switch to operate the EQ section needs to have a shielded cable and plug.

| My old (earlier model non-reverb) Super Twin didn't come with an EQ footswitch and I can't remember now if it had an EQ footswitch jack.The EQ section was always in unless zeroed out. After 40 years I also don't remember the EQ settings but I do remember steel sounding pretty clean through it! There's a non-reverb Super Twin on Denver CL for $400. |

| Are these controls of Equalization the same on a super Twin Reverb as they are on a webb amp if so what are the settings for a Webb amp's Equalization? |

I have nothing on the Webb amp question, except every amp is different.
In your original post, you asked about achieving a maximum clean and bright setting. The knob labeled “Volume†is your master volume. The one labeled “Output†is your gain control. Turn “Volume†up to 10. Leave “Output†as low as possible for the volume level you want. If it’s still too loud with Output on 1, turn down Volume. Cranking up the Output will fatten up your tone as well as increase volume.
Start with all your tone knobs set to 5 and adjust from there.
You also have a bright pull switch on the Volume knob. Pulling that knob out engages the bright function. With that, along with the Presence knob, you should be able to get ear piercingly bright highs.
If you don’t have a footswitch for engaging the EQ section, setting the knobs at 0 leaves all the tonal adjustment with Treble, Bass, and Mid knobs.
A lot of this is explained better in the manual, which is linked in my earlier post. |

Arguably, the best steel amp ever built, with tonal variation that is literally impossible to get with any other amp. (Though the Mesa Boogie III-C with the graphic EQ comes close.) The super power and active graphic EQ network is what makes it so.
If you don't know how to use the extra knobs, set them to zero and use the bass-mid-treble as normal. Outside of that, no one can tell you where to set the EQ knobs because they don't know what kind of sound you prefer. |

I have the Super Twin without reverb and love it. I got one after reading many of Donny's positive posts about them. Both models had foot switches to switch between the usual tone knobs and the graphic eq, and former's settings impact on the latter when activated (at least on the reverb-less model), giving you a massive range of tones. When cranked you can hear beautiful clean sounds from the next block away (or so my son told me once after he was out walking. Disclaimer: he may not have said 'beautiful').
I set the graphic eq for a good trebly, cut-through sound and switch to it and the boost for solos with the foot switch. The foot switch can be a bit awkward so I've been looking to turning it into a hand activated switch and sticking it on the leg of my steel.
My advice: listen to Donny's advice on anything to do with this amp and check out his past posts: https://www.google.com.au/search?q=%22donny+hinson%22+AND+%22super+twin%22+site:steelguitarforum.com&source=lmns&hl=en-GB&ved=2ahUKEwjqh43CtdrpAhU7DrcAHQV9DbYQ_AUoAHoECAEQAA |

Interesting.
I did not know that Fender made a Super Twin without reverb.
Do you have a picture or any other information?
Thanks in advance. |

The Super Twin was only made for two years, 1975-1976. The (later) Super Twin Reverb was made from 1976-1980.

"Output" is the master volume.My old non-reverb Super Twin looked exactly like the pic Donny posted.A nice little trip down Memory Lane!  |

Fred was wrong on that one.
The people here who have actually owned one of these probably know what they’re talking about. The knob labeled Volume is your preamp level control and the one on the right end labeled Output is your Master Volume. Just like any other Fender ever made. |
