Volume pedal resistance(ohms)

Recommended Posts

I'm looking at some of the ernie ball vp's on ebay and a check of the eb site shows that they come in two different resistances, one for active instruments(25k) and one for passive instruments(250k). I play one passive/active bass and one fully passive bass. Should I risk getting the passive version and dealing with possible distortion. Or should I get the active version and deal with loss of high end transients. Or do these pedals no follow these "standard" rules. Any experience guys?

I would think the passive pedal would be your best bet, you would just have to set the level on the pedal to your active bass. If there isn't a level or gain/volume knob then I would turn the volume down on the active bass. Sounds like a pain in the neck.

 

I have an old Morley volume/wah. When I play my active bass I click off the boost switch and I'm set. When the wah switch is clicked off it functions as a volume wah. And it must be true bypass because I lose absolutely NO tone when I play through it, and the wah has such a tasty growl, great for funk!

Get the passive one; the active one will reduce the highs coming from your passive basses. The downside is that the volume pedal will act more like a switch when you're in active mode.

 

You won't get any distortion either way - the choice of impedance just affects the way the pickups are loaded.

If you use some sort of "stomp-box", it would generally have a hot enough output to drive the low-impedance volume pedal no matter which bass you used.

 

I recently went through "the quest for the ultimate volume pedal" too. Because of problems I read in reviews, I went with Morley:

* Ernie Ball pedals supposedly need pots replaced periorically (and string can break)

* Boss pedals tend to have a problem with the internal linkage "slipping"

 

The above is according to reviews, not my experience. You can finds lots of reviews at: http://www.harmony-central.com/Effects/Data/

 

I went with Morley, for the optical mechanism (nothing to break, in theory). The Morleys come only in "medium impedance". I've read reviews saying some guitar players hear a loss of "highs", but others dispute that.

 

The Morleys come in the two versions: Linear taper (Little Alligator) and audio taper (Pro Series Volume). I'll defer to others to explain the difference...

 

After a lot of excitement, I quickly ended-up "throwing in the towel" - bought it, shelved it. Gained new appreciation for a) on-bass volume control and b) controlling volume with fingers.

So ... I you have an amp that has a "bright" feature (Peavey TKO 115 for example), which supposedly boosted the highs, you don't get that back? (The ungainly fiddling with the amp buttons while playing and operating the pedal simultaneously aside ... this is strictly a theory application question).

 

And ... if one were to try the hands off approach, what about buying an equilazer stomp box set up with the midrange and highs a little higher and hit that before using the volume pedal? (Cash limiting, but again a theory question)

One more question.

 

I see that the vp jr from eb is cheaper than their full sized vp. Is this ONLY due to the smaller amount of material used, or is it "smaller" in other ways?

I read that the full sized eb was longer and wider

 

The VP's dimensions are approximately 11" x 4" x 2.75" and they weigh about 3.75 lb. The VPJR's dimensions are approximately 10" x 3.5" x 2.5" and they weigh about 2.25 lb.

 

straight from the ernie ball site.

Well firstly, you can't put back highs that aren't there. If you have lost some treble and try to EQ it back in it always sounds thinner, dirtier and less pure than if you hadn't lost it in the first place.

 

If you put a buffered bypass stompbox before the volume pedal that would solve the impedance matching issue; but you would suffer the tonal degradation from the buffer. However, I've found that's Boss's pedals don't add much noise or change the tone noticeably.

 

I use a volume pedal because I have a stupidly large effects chain and like to be able to keep the wilder effects under control; plus I use it for synth/strings/whale noises. If I wasn't being so effects happy then I'd just use my volume knob. As such, I place the volume pedal at the end of the chain.

It's significantly smaller in every dimension and far lighter (and the weight adds up once you've got a whole bunch of pedals). I bought an original VP (passive) and replaced it with a 25k VP Jr. I like it.

 

Why do you want a volume pedal MF?

Ive wanted a vp for a while. Whenever I ajm with friends I'll just use my volume knob to get that sound that I hear in my head. When I'm playing a show where those little glitches in my playing count however, I feel it's too risky. So the volume pedal is to gfet what I hear in my head into others' ears. I tend want swells into and out of notes and I like using the knob to get a little bit of that "delay" effect, or a controlled echo also
