OK folks,
here it goes: to set global reverb/hall effect on the T1/T2 and I believe 3000:
Hit the mixing console button to bring up the mixing console page, then right tab over to effects, then hit the F button "type", then hit button 1 or 2 on the bottom of the screen up (in the block area) to go to reverb which is the global setting for styles, song, R1,2,3,left and vocals, then go to the right hand side on the screen to "Type" and scroll down to Stage4!
That's it.

Then save to registration memory.
If you want it even more dry use one of the Room types.

Play with it and see what you like.
A few styles are programmed in the type of Hall1 and are somewhat dry to begin with. If you use Stage4 on those styles you will actually add reverb.

Use Room instead.
Next I went to CMP by using the tab button to the right twice and set it to "club"
That adds a nice punch to the global settings and styles.
Of course for each style and song you have to do the same and save it to registration memory.
If you call up a style from the style banks it will default to factory settings.
Except for the global Club setting, all others will default back unless you use registration memory.
I hope this helps
Eric
