HolyDirt said:Hey guys, i need a good volume pedal, one that keep the tone of the guitar, but just changes the volume... i dont want the low volume sounds to sound clean if everything else is distorted... is this possible?
HolyDirt said:so putting a passive volume pedal after a distortion pedal or in the effects loop will get what i want? seems like it's be harder than that... oh well!
Thanks kent, the first time i used a volume pedal, i built it, just a passive volume rocker pedal, i thought it would act as just a volume knob like on the guitar (like you said) and when i tried it, it did just that. But i just built another one out of a wah pedal shell, put it in the effects loop.. it worked beautifully! thanks guysKent S. said:In front of the amp the only thing you are doing is the same as turning down you guitar's volme knob, but with a pedal.

ah i see, that explains the boost of warmth and darkness in my tone after i began using it (i changed from using in the loop, to using it before a distortion pedal but before the amp, btw), but i'm leaving it, it sounds really full! But i still dont get why the 2 500k pots together are parallel... i would think it would be series... well.. anyway.. thanks kent!Kent S. said:One more theing that no one talks about, say your guitar has a 500k volume pot, you you run thru a volume pedal that has a 500k volume pot (for example) ... you just hooked two 500k pots in parallel ... that's a 250k load.
If you just wanted to regulated you *guitar's volume* with a volume pedal, the smart thing would be to use a sizeable gauge of wire, and bypass the guitar's volume control via a switching jack.
Putting a volume pedal thru the amp's loop, the pedal should be a lower impedance than what you would normally use for straight into the guitar.
The BOSS FV-50L works well, and the 300 series is supposed to be *sworn by* as to not interfere at all with your tone in the slightest. See if you can find a schematic of the FV-300L.
Another note also, most volume pedals because of the way they are wired can be used as passive expression pedals, on any two wire circuit. Simply connect the expression pedal line to the *output jack*, althouh the value of the pot may be different than the one that the circuit wants to see, so it's most often will still work, even though you might sacrifice a bit of range though.

oh! i get it! you know your stuff man!Kent S. said:You're kinda confusing me here, if you put it after the distorion pedal, then you may want to go with a lower impedance volume pedal (you really just have to try to different types to see what works best here though in regard to before the amp but after a distortion pedal ... especially if still going into other pedals ...Dist.>Volume>other pedals>amp.
The volume pedal shares a common ground with the guitar, the two are in parallel, running after a pedal with it's lower output Z buffers this somewhat, and make the effect less noitceable. Draw out on paper the schematic of the volume pedal and the guitar and you'll see that the 500k pot (for example) of the guitar is in parallel with the 500k pot (for example) of the volume pedal.
500k to ground in parallel with 500k to ground is 250k.
