fv500 with a moogerfooger. think i bought the wrong one.

[Omniant]

So I bought a really durable expression pedal to control my moogerfooger's cutoff and I think I may have gotten the wrong one. Boss makes the fv500h and the fv500L. I purchased the H, was I wrong? I mean as far as I know the H was for mono signals. But I can tell you for sure the H isn't working right.

Anyone have any ideas?

It has nothing to do with H versus L.

There is a good chance that the pot is not wired to the jack in the way it's supposed to be for Moog products. There is no standard for exp. pedals, so Roland/Boss expression pedals are only guaranteed to work with Roland and Boss products. I checked the manual but they don't show a diagram of the wiring (for shame, Boss!).

The Moogs send 5v on the ring of the stereo cable, ground is the sleeve, and the divided voltage (which corresponds to the wiper or center lug on the pot) is on the tip. Boss very well may use a different setup (haven't opened one up) so if this is the case, the only way to use that exp. pedal with the Moog is to rewire the exp. pedal.

You want to connect one outside lug to the sleeve, the other outside lug to the ring, and the wiper/center lug to the tip.

mike at www.putnamguitars.com could probably do the mod for you. send him an email through his website. great guy!!! or, you can just give him a call and talk to him about doing the mod.

peace & music,

The H is for High impedance, from what I understand. The L version is ...well, sure you can guess.

[Taylor Livingston]

Yeah, but impedance doesn't matter with the expression output.

[superbassman2000]

the FV500 isn't a cv pedal is it?

or wait--the moog pedals can accept non-cv expression pedals too right?

[warwick.hoy]

It's an obvious question but just to rule it out,...are you using a stereo TRS cable?

[Omniant]

yes...does not solve anything

[VermonaLisa]

if I'm not wrong, the fv means foot volume, so they might not be cv pedals but volume

[Taylor Livingston]

They have expression jacks. They can be used as expression pedals, and Moogs work fine with passive voltage dividing expression pedals. The problem is very likely what I wrote above.

[Omniant]

Yea you may be right. Unfortunately I'm just not tech savvy enough to know how to do that.

[Taylor Livingston]

I'd take it to a local guitar tech. It's a very simple mod to do, 2 wires to be swapped.

Anywhere online I can find a tutorial on that mod? Also, if I used this on my fooger accidentally without the mod is there a chance i messed something up?
