Two masters?

[Tdale]

Is there any problems involved with using a clean master (wired at the Clean/OD switch) And a global master, wired after the OD pots?

This means that when using the clean channel, there are actually to masters in series, while using the OD channel, there is only one..

any problems with this?

The Hybrid has a master, and an OD level control. I think that's what you're talking about.

What you need to be concerned about it the loading on the stages. Make sure that you have the correct resistance on each stage, in and out.

[Tdale]

Yes, it has a standard global master..and of course the level control in the OD section.

But could I add a clean master too, withouth doing anything with the values of the other pots?

I realize that in clean mode, I would go through both the clean master and the global master... maybe that's not a good idea?

I don't understand the purpose, these Dumbles are complex enough to operate.

[Tdale]

The purpose is to be able to control the master volume of the clean channel independently from the OD channel.

I guess the two masters would have to be totally independant for this to work right...

If yours has a global master and you want to isolate the channels, just replace it with a clean master. The level is a MV by another name. I set my HRM OD a little hotter than the clean and control with rest with the guitar. If you need an overall master, there is no crime against putting a post PI MV that wouldn't load the preamp. That said, I wouldn't. Skip

+1. The benefit of either a clean master or a global master is that the clean gain can be set to about 5-7 and still be clean with the master turned down and give a good range for the OD sounds. I have tried both topologies and both achieve this result.
If your amp has a buffered effects loop with a return volume control you could use the return volume control as a global master. I believe this is what many Two Rock users do.

Update: after installing a global master in the Deluxe Reverb II I find it to be indispensible. It lets me turn up the OD level past 2. The amp sings a lot more now and is much better controllable. I used an 1MA pot with a 47pf bright cap.

I want to do the same thing to the Concert now since this amp is freakin' loud. I can only tame it by turning down the return level control of the effects loop. Unfortunately I ran out of 1MA pots so I will have to make do with a 500kA pot for the time being.

I tried this idea as an experiment and it worked well, no diff in tone.
Didn't have room to make it a permanent fixture otherwise would have left it in. YMMV.

Totally agree, just put a global in my HRM amp, close inspection of the real thing shows just that, only one pot with bright cap, and that`s the MASTER next to the pres pot, the Content and level look just like the 80`s set-up. FWIW, i was able to dial in sounds i`d never gotten before and TOTALLY righteous, and too, the CLEAN channel gained a fullness and life it didn`t have before. In my heart of hearts this is right! GOIN GLOBAL BABY!! lol!!

I am confused. The global master is the clean master in all amps. The clean tone should be exactly the same. In my HRM amp, I have a bright cap on the clean master and the ground is modified so the bright cap has no effect on OD tone.

That makes perfect sense to me!!
