I think if you want to mod your amp, first do your homework... learn about the design. Only then you will be able to understand what those gurus are talking about and only then you will be able to make your own conclusions and decision what to change.

For example, if you want to make your OD sound darker, there is a lot of things you can do to achieve that. The easiest way is to follow tweaked layout from Jack but what happens if your clean channel now sounds to dark ? .... see, only if you know what those elements are doing, you will be able to make the right decision.

...or go to an amp tech who knows these amps and he will do it for you but expect to pay some $$$ for that. ...and not any amp tech will do, you have to know these D style amps to be able to tweak them.

Chris, all I can say is, I'm with you on this...
 

 

I have BB and RC as well (TS9 is there as well) and like Chris said, you can get huge tone with those pedals. I really like the tone stack on these Xotic pedals, it really helps with shaping your sound.
 

Well this Jack Z. definitely owns a tube amp, so maybe he changed his mind or there is more than one Jake. Z.

 

 

Mmmmmmm, I like it.
 

Cool rig
 

Maybe you'll find your info here...

I'm waiting for mine but still my assumption is, you don't want to overpower PI tube, so basically what I would do, is to brig the output level to the same level as if you would not have Kleinulator in there.

Does that make any sense?

Greenback with the deep switch ON does not sound thin or harsh to me. Even without the deep switch it still sounds good to me, very Fendery if I'm allowed to say that.


Marin which one do you like best G12-65 or Greenback?

For me the best sound happens when both are used at the same time.
 

I think you are infected with this tweed disease and there is no cure for it I'm afraid.
 

Tubes are important too, so difference between those two amps could be the tubes as well.

Welcome to the forum.
 

Regarding the mid tone section I read on the TAG forum, that if you want more low mids for example, then adjusting the mid cap is the easiest way...smaller value gives more low mids.
If you want more high-mids then increasing the treble cap would be the way to go and if you want 'more of everything below the high-mids' then decreasing the slope resistor would help.
The slope resistor mod will increase the bass along with the mids/low mids where the Mid cap mod will tend to just focus on the low-mids.
Something like that...

or
You could also try to play with mid control network... currently you have 250K/.001 and you could go with 100k/.05 which would give you even more "mid range sound". You could of course try different caps like .047,.022 and by putting a resistor in parallel with a 250k pot, you can make the pot whatever value you feel like.
...but hey, I'm not an expert, I'm just a guy who read everything on Dumble amps I could find on the web. 

My first amp from Nik was a 5E3,... today I have three Ceriatones and I'm selling my Fender.
...and when I was buying my 5E3 I said, OK that's the last amp I'll buy.

 

What tubes are you using currently? For example Ei tube  will give you far more sparkle compared to TungSol or JJ.
If you want less gain 100KL on the OD level is the way to go, just in case you're still using 250KA.

BTW what is the value of your bright cap?

All I can say is 



 

Nik, you should have take the money and give me a bigger discount on the next amp I order from you, sometimes in the future. 
Ignorance is not an excuse IMO, so you do your homework or you pay.
