Madness!
Haven't tried a Chromatron, but the filter series seemed to be getting progressively less interesting since the GR2. I wasn't impressed at all with the Wonderlove. I wouldn't feel compelled to pay anything remotely near those prices. I find it impossible to believe someone would pay £800 for an Octabvre, a pedal cloning an OC-2 and an Octave Divider, and selling for more than both of the originals would combined.
In fact the only pedal I've really been impressed with is the Doom, as it went somewhat against Spencer's usual remit (an actual original design), and the Doom 2 seems to get people excited.
I don't like the guy, but I hope he's okay as it is odd that he's stepped back during a time you'd think he may really boom, as others have done.
