Sorry to report that it appears OverToneDSP, a plugin developer whose products included emulations of SSL, Pultec, and Fairchild gear, has vanished. 
 
Their website is blank, their KVR forum was moved to the "old" section, and nobody seems to know what happened.
 
Very disappointing, as their stuff was high quality and priced in no-brainer territory.
 
Anybody with any info, please post if you can.
 
Cheers,
Eddie
 

True, and they just added that new EQ (http://www.musicradar.com/reviews/overtone-dsp-eq4000).

True, and they just added that new EQ ().

Thanks for sharing new EQ address. 

Oh no! They had one of the best PulTec emulations out there. I use their products all of the time. What a bummer!

I need to get that 4000 EQ. For Mac. Now.

I emailed them to find out what's going on but no response. The thread over at GS mentioned something about SSL but I'm not sure what that meant.

It's probably a one-man operation, so he may have suffered an illness or otherwise had to give up his business. Maybe someone in Oxfordshire should go knock on his door and see if he's alright:
 
    Michael Robert Start
    White House Cottage, Denchworth Road Grove, Wantage, Oxon, England, OX12 0AR
 
I've actually been to Wantage, strangely enough. It's not far from where I used to live. And a very small town, so an inquiry at the local pub is likely all a detective would need to solve the mystery of Michael's disappearance.
 

Great idea. Anyone on this forum living nearby?

It's odd that until recently, Mike was posting on forums and touting the success of his latest products. Simply disappearing seems like a strange way to go out of business, even if it was caused by illness.
 
Cheers,
Eddie
 

Well thankfully Overtone appears to be back with us.
