vaccum/silicon and spongy/bold

[crankyrayhanky]

Hello Board

I recently acquired a 2channel Dual Rectifier (Rhodes modded)
Flipping through the settings, the tonal changes are clear, but I'm curious- how do people set the switches: vaccum/silicon and spongy/bold?
I typically play angry aggressive metal detuned stuff, so I am told silicon bold is the way to go (?) seems to sound great, but check me on this...also, does this mean the big bottle tubes are being unused? I know, total newbie questions

I like all kinds of music, so if anyone can give me an example of the type of music you may play in each setting, such as "brown mid gains, 80s west coast happy metal, pop mid gains" etc.....that would be a big help. Combinations include:
vaccum spongy
vaccum bold
silicon spongy
silicon bold

If you're feeling frisky, you can comment on the above with the orange/red & vintage/modern combinations
orange vintage
orange modern
red vintage
red modern

I think I have this down pretty good, but the spongy type settings I would love to hear comments...thanks in advance!

Hey man, saw your post on rig talk, I commented there as well in case you head there first.

When you use diode rectification, the rectifier tubes are taken out of the circuit but the tube heaters are still on.
For anything heavy I prefer diodes and both channels cloned to modern, just a faster tighter response out of the amp.

The rectifier tubes introduce a slower response and more sag/bloom from the amp, which in turn works well with both channels cloned to vintage with the cleans and vintage rock tones.
I mainly play metal these days but will go clean every now and then.

Thanks- this makes things very clear for my fuzzy brain

I typically use mine with the amp set to spongy/tube rectifier. Those settings drop the output to somewhere around 60w, so I can crank the master volume a little harder. I'm after more of a sludge metal sound and like the extra swirl and harmonics this setting provides.

Bold/silicone is more articulate and hits a little harder, but I find it a little too clean for my tastes.
