So I guess SRV, Bonamass, Eric Johnson, clapton and Jimi sounded muddy to you?I honestly don't see how anyone can play a guitar with the volume tunred down without some sort of treble bypass. Most guitars turned down lower than about 8 sound horribly muddy to me, so bad that it's almost unusable.
What's a good way to figure out what to use?It totally depends on the size of the cap and whether it has a resistor either in series or in parallel with it.
You can have any effect from no detectable change compared to not having it, to extremely shrill and harsh when the volume control is turned down, and all points in between.
Saying you don't like treble-pass caps (it's pass, not bleed, BTW) is about as sensible as saying you don't like single coil pickups because they all sound thin and weak.
No offense intended.
And yes, most treble-pass caps on guitars are overdone.
I would like to see what John says here too.What's a good way to figure out what to use?
Experimentation, unfortunately. There is no 'right' value or combination of values - it depends on the pickups, the pots, the guitar cable, and what you're plugged into, and this can affect the ideal values by up to a factor of ten.What's a good way to figure out what to use?
Exactly. 'Bleed' is totally the wrong name for this circuit, and means signal leaking somewhere it shouldn't - either to ground (causing loss/'suck') or into another part of the circuit when you don't want it to (eg between channels on a channel-switching amp).I also mentioned in a different thread not knowing where this "treble-bleed" idea came from, but I think generally a bleed is when
some signal or part of a signal is shunted to ground, which is not what is happening here. Here we give an alternate path for
certain frequencies to make it through the pot more or less "untouched".
That's true, but the bulk of his tone came from his Tube Screamers, which produce pretty much the same output tone even with rolled-off treble on the input .One thing everyone is ignoring is that the eq rolloff you experience with the volume control is part of the tone that we all know and love, just like passive pickups, tubes and overdrive.
Listen to Stevie Ray when he plays texas flood or Lenny and turns the volume control down. It's gorgeous.
