6386 Manley Vari Mu Vibe Loss?

I read when earlier 6386 tube Vari Mu's get upgraded with highpass switches they loose their "vibe". I know they definitely have vibe, does this mod really change that?

Can anyone with direct experience comment please?

That’s absolute nonsense. I had one from the late 90’s added both the HP and TMod and both mods improved it by a massive amount.

You might be a bit confused. The non 6386 Vari-Mu’s have a different “vibe” to the earlier models that used that tube. Manley had to make the change as 6386’s became harder to find/more & more expensive. The filter mod/upgrade doesn’t affect the sound/vibe.
If you can get an older 6386 model (but save up for replacement tubes!).

I know T bar mod affects the compression behavior, allowing for improvements at higher levels of gain reduction. But does it affect the box tone when no compression is used? I know some slight compression occurs even with threshold all the way up, but does the mod affect the overall boxtone of the Vari Mu?

No same tone, w/ TBar more forgiving compression behavior.

Yes to clarify I read that adding the sc hipass filter mod to a unit like the 6386 model that doesn’t originally have it makes it loose it’s vibe.

Adding the mod does change its circuit, extra wire, parts, etc.. Thats why was checking to see if anyone had direct experience with this. Thanks for the reply.

Thanks a bunch. I was contemplating the mod, but I really only use it for the tube flavor on the input. I have threshold all the way up, attack at slowest setting and release at fastest setting. Its a beautiful box and I don't know what I would do without its footprint on my sound.
