This is based on original design by Merlin over at ValveWizard.com. Board by EffectsPedalKits.com.
Easy enough build, and there's only two off board components so I'm happy.
Soundwise, this thing thumps. It's clear, it tracks quickly, and it doesn't seem to glitch out as easily as the OC-2 based circuits. The build docs calls for a TL072, but this didn't sound good at all- the decay was almost like a Prunes and Custard. I have an NE552 in it now, with a handful of LM833s on the way. The 833 is what the designer intended to be used in the comparator spot, so hopefully that works out the few wrinkles left in the sound. It does sound vastly different depending on pickup position, with the neck being the most chest-pumping
As is, it sound pretty good, tracks well, and unlike a lot of other "clean" analog octaves, it has some decent volume on tap, and an internal volume trimmer for the -1 signal.
I'm hoping with the correct chip, I'm able to get closer to the sounds the other demos online show.
I built two simultaneously, they're identical except for a few parts types (electrolytics) and the different JFet part numbers used. The one in the vid uses a 2N5458, the other uses the J112 the build docs calls for. No reason other than I only had the one 112 on hand.
