|Gil Ayan||Weird Report, Steve... Re: humble clone|
The presence control on many Humble clones is a bit weird... I just barely crack it open and it sounds like a "regular" pc set to 4 or 5... If I turn it up to 4 or 5 the sound is way too bright.
The Dumble's presence control works like every other presence control (true presence control, that is) which uses a linear pot. That is, it does nothing until you hit the 1-2 o'clock position (so that's like 6 or 7 on a 1-10 scale) and it begins to breathe from there. The real amps do this, all three of my clones do this, Marshalls do this, Groove Tubes Soul-Os do this, etc.
There are amps which are exceptions: MB MkI Reissue, because its presence control is simply a tone control with an audio pot dumping highs to ground; the Rivera-design Fenders, because they used reverse-audio pots in the presence positions.
As for the amp being too bright with the presence cranked up... aren't all amps that way? They are to me; I like the presence when it's just cracked open. Anyone who's had a chance to see LC or RF with their amps will see that they set the presence control at about 1 o'clock or so, that is the threshold of where it begins to do anything at all.
