Hello. I would like some advice on what can be done to tame the shrill high-end I'm getting from my Ghia. I have a brand -new Ghia head that I'm running through a closed-back 1x12 cab with a Vintage30 in it. the cab is fairly new too.
I cannot tame down the treble on that amp when I'm using the bridge pick up of my strats and teles. I have the tone set at 3:00 and its still too much treble. Anything more then 3:00, and the sound becomes muddy.
I realize that a speaker change may help, but its not an option at this time. I also don't want to become reliant on an EQ pedal.
Is there any mods that I could have done to taper some of that treble from the tone knob??
Please help!

You can turn down the tone knob on the guitar. The problem with my strat, though, is that the bridge pickup isn't connected to a tone knob...
Also, if you don't need all the volume of the Ghia, you can use an attenuator - those will knock off some of the highs.

I'm using DiMarzio VV pups on my Strat and rolling back the volume on the guitar ever so slightly takes a little of the highs off. Not sure if this'll work for you, but it works for me. It sounds like you already realize a speaker swap may be the best solution, good luck.
Oops, I just realized this is the 'experts' section. Errr, um, 'scuse me while I run outta here ...

I would think an EQ pedal would help, but I've never had that problem with my Ghia. I know you say it's not an option right now, but your best bet would be a speaker change. If money's the issue, you might try to trade with someone.
I'm not a big fan of trebily sound, and I couldn't be happier with my Ghai and Strat combo.

Try it with other speakers, the more neutral the better. the V30 has a pronounced nasal honk.

DC here!
1) Talk - email to Doc and ask his advice.
2) You almost certainly - have a capacitor connected to the tone pot on your Ghia. In principle - change that capacitor - with another - with a different farad-value.
This will change how - much/little - treble is - cut/added - when adjusting the Tone control on your Ghia.
Caveat: This operation may change other parameters in the pre-amp chain - better check with Doc first.
Cheers: Dixiechicken!

If you can stand it, give it enough time for the V30 to break in. My Ghia 1x12 combo with a V30 was IMHO terribly harsh and bright when I got it new. After several hours of loud (read on 11) playing the speaker loosened up and the harshness went away. I am now very pleased with it and after comparing the Blues and Gold I think I will hang with the V30 for its aggressive Marshall vibe. I was thinking all sorts of things before it transformed, mod the amp, change the speaker, go to a closed back cabinet, etc... I am very pleased now. Crank it up and let er rip for 15 to 20 hours and it will be a whole new animal (great excuse to lock yourself away for a weekend with your guitar and amp). ;D

I agree T-bar - there is something nice & Marshally about the Ghia & a V30. I'm currently using a blue but I'm hangin on to the V30 for sure...
As far as taming that high end - I would get a couple of different tubes for V1 and experiment. I'm betting it's just a high gain, bright tube you've got in there. I tried 4 different 12AX7's until I found the perfect fit. The JJ and EH were too bright to my ears, the 12AX7M too dark but the NOS long plate Sylvania (Hammond organ tube) I had laying around was just right...
The ghia is so responsive to tube change. What a great little amp..

Yeah if a speaker change is not an option then i would give Mike at KCA tubes a shout and explain to him what you are seeking. There are many NOS tubes that have well known general qualities or character, and you should be able to see some pretty decent changes by proper selection. For instance, while they are pricey, a Mullard 12ax7 will have a definite "warm" bump in the midrange and a slightly recessed high end which would tame some shrillness. There are many to choose from and it gets quite fun when you start to collect and assemble a "palet" of tones to choose from much like a painter would select colors. You will learn these tubes colors, and know just which one to reach for when you hear something you want to change. Dont try to do it overnite, but just make a point to start trying to find a deal on a tube or so here and there and before ya know it you'll have a bunch to play with!
