I bought this unit in April 2008, and used it perhaps 10 times in my house.  Practically new condition, though I can't find the original box.  I do have the original manual.  Before I put this up on ebay or craigslist, I thought I'd offer it up here.  $200 plus shipping.

That's about what they go for new. Any flexibility on the price?

Really?  I saw $279 at amazon, $279 at pedalgeek, and $279 at musiciansfriend.  I'm certainly not trying to ask for more than a fair price, but on ebay's completed listings used ones have been selling at $200, and plenty new ones at $279 and even higher (why would anyone pay more than that anyway?).  I'm confident I'd get about that if I put it on ebay, but thought I'd offer it here first.  What do you think is a fair price?  Would photos of it help?

$200 is a fair price Mark, especially if it's like new.  
 
If I didn't live in the tax you to death state, I'd have snatched it up  yesterday....

And if I didn't live in the tax you to death, than bring you back to life and charge again, but double this time country, I'd have bought it in a glimpse too.
I've been wanting a Moog pedal for quite a while....
Good luck Mark!

Thanks.  Yes, it really is practically unused and in pristine condition.  I'll leave it up here for a few more days before posting it elsewhere.

$200...I'm pretty interested, but thinking it over. Feel free to contact my via email.

I have had an MF-101 for years. Great pedal. You can use it as a envelope filter type of wah, or you can sweep the filter with an expression pedal. Actually, the control voltage (CV) inputs and outputs are the key to unlocking this thing. This was my entry into analog synthesis. I like to use a sample-and-hold to control the filter, whether it's stepping or randomly controlling the filter - useful when also playing bass pedals! You can also use the envelope follower to control other things.
 
But it is great as a standalone auto filter - especially with the mix knob which lets you maintain your original signal along with the effected signal.
 
Good luck with the sale!

Sold to a clubmember!  It's a pleasure to find a good home for good gear.

That would be me...a New member since 2003.

Gerry, That's very cool! Welcome back Congratulations on your acquisition of the Bob Moog legacy.  Art
