I  tried with my cheap Digitech Digidelay (which doesn't color my tone on my old Marshall modded (with a tube buffered effect loop).

In the overtone, there is a significant lost in the highs.

It should be could that Nik will make a kit for a 63' Fender Reverb Unit !

Someone shoud ask him to.

This unit is simple, and can be a cool "first" build I think.

How will you do that ?

You need to put an extra piece of wood with some tolex on it ain't it ?

I think I will do something like that, I really like how it looks with the grill coth on it.

Thanks for your help I will check this.

I feel a LOT aimed in this thread.

What's the problem ? 

As erwin_ve said, tweaking an amp isn't that simple.

You have to be careful and have already some knowledge in electronic to not killing yourself with a charge coming from a capacitor.

I will done some tweaks/mod and maybe others and they will be do by an amp tech !

I spend long time on the amp garage forum, and exchange few mail with people which HAVE the knowledge to mod a D-style amp. And I'm happy that on this forum too lot of people try to help me.

And I will do some tweaks, but KEEP in mind that see how an amp will sound like just by watching the layout or tweak an amp is not as simple ...

I feel it's a bit pretentious to say "Oh my god, just tweak your amp if you're not happy with it ! YES it's harsh haven't you see the layout ?!"

I don't understand why it's getting on you nerve that people don't like the amp the way it is actually (with no personal tweaks), for me it's just "normal" and as the overtone will get famous as more you will have that kind of post.

I enjoy the fact that Dumble style amp is getting more democratizes and will not be reserved to some kind of an "elite" of people who can know how an amp will sound like just by reading the layout ...

So sorry ChrisL but as the Overtone will get famous they will be more and more "noob-post" like mine asking for some help with tweaks.


Best regards

ps : I'm in the same case as erwin_ve, I'm not a native english speaker so for me tweak and mods are the same.

Are you using a dumbleator or a kleinulator ?

Maybe it will resolve my problem !

It's kinda strange that I'm the only one who have some prob with the OD brightness.

My Kleinulator doesn't work (the little chip in it has blow when I first put on the divice, I must receive another chip in few days). The Kleinulator should smooth a bit the amp but will affect both clean and OD channel.


Hywelg, is the 5751 a 12AT7 ?

Thanks for your advices .

I'm a huge John Mayer's tone too and I have a Overtone (I purchased the Overtone with the hope to approach his tone)

First time I plugged my Overtone I was impressed the clean channel is great (very fenderish) etc but past the excitement of a new gear I have to admit that the Overtone doesn't do the "John Mayer's Tone", I'm really disappointed with the OD channel !

Why ? Because the Overtone has so much highs and treble on the OD channel (it's sounds aggressive). I've already change the OD trimmer for less gain et a smoother sound but it's still to edgy.

The amp still need some tweak. I'm currently selling some gear to get some cash to buy some other stuff (other guitar) and to mod the amp with my amptech.

My amp have the actual layout from Ceriatone (which contain a big part of J.Zucker mods). But it's still to edgy. For those who's wondering I mainly play stratocasters through an old 4x12 Marshall Cabinet loaded with G12-65 or a 1x12 with a EVM-12L (these speakers are not "harsh/trebble" speakers !

I'm sure I can get closer to a Two Rock with a few tweaks for the OD channel I don't think it will sound like the real thing but I'm sure I can get close.

Keep in mind that John Mayer doesn't really use his OD Channel, he mainly use his two rock as clean amp and running his pedal through it (T808, Marshall BB-1, Keeley Katana, Keeley Blues Driver and Hermida Zendrive) for his dirty sound.

His Two Rock's signature is mostly a Clean amp !

For instance I'm also playing the Overtone on the clean channel and running my pedal through it (Fulldrive 2, a Xotic BB Preamp and also a Marshall compressor).

With the Fulldrive and a Strat I can get pretty close to "Good Love Is On The Way" type of tone. But if you want something more "liquid" / "cooler" / "smoother" it's another story. The only way I find is to roll of the volume knob of my guitar pretty low and dial with the tone controls of my strat. But when you do that you miss a lot of precision in your sound and it's doesn't sound very good.

I think that for a John Mayer tone, you can also go for a Super Reverb / Twin maybe a Bassman or a Pro Reverb with few pedals, and you will get close too.

I really dig the Two Rock Custom Reverb Signature sound but the Ceriatone doesn't do it (I'm not bashing the Overtone it's just doesn't suit my taste for the moment).

After the tweak were done (if you have any suggestion about tweaks / mods please tell me), I will make a review of the Overtone and I hope I will be 100% satisfied.

That was my opinion

Here the schematics I get for a 2x12 Two Rock Signature like.

You should use multi-ply birch.
You need to center the oval open back and to not make the handle's holes.

I plugged my Fulltone FD-2 Mosfet, my BB preamp, my Marshall ED-2 in the Overtone, and all sounded great too ! Specifically on the Clean Channel, as I said in some other post, my OD channel need some tweak to sound good (the OD is too bright and when I add a boost it get worse).

Jack Zucker posted few clip of his Overtone with a Fuzz on youtube, you can have a quick overview of how it could sound !

Sound is before everything in the fingers we all know that

I was not aware that this mod was possible ! If I knew that few weeks ago I would sure asked Nik for this mod !

I have to mod my amp (to tame some of the high of the OD) and I think I will make this mod.

I don't think I will make this mod myself, I'm not able to do them, I will certainly give my Overtone to my amp tech.

That don't change my problem, even after turn down the OD trim it's still too trebbly / agressive for my taste. (I'm using old 12-65 in an old marshall 4x12 cabinet, not a trebbly speaker !)

I think I need some "tweaks" but I don't know which ones ! I mainly play strats, and I want to get close to that sort of liquid / sweet tone that John Mayer can obtains but I'm pretty far away !



I know that a 1k$ amp can't do what does a 3k$ amp but I'm sure that with few tweaks I can get closer to that sound.
