BJFE - Emerald Green Distortion Machine
Posted: 23 Jul 2009, 03:23
I haven't seen this one brought to the table or discussed so I thought I'd mention it. Could it possibly be a HBOD or DRD variant with less high-end filtering?

This is all true. Is this a gooped circuit as well?Greg_G wrote:Very likely a similar design with different voicing I'd say.
IMO BJ is clever at tuning his circuits.. and what may appear simple or similar to something else generally produces a unique and great sounding effect.
This should probably go in the Members section for now, as there's no information attached to it.. but if anything is forthcoming it can be moved back into the technical area..
AFAIK all the hand built BJF pedals are gooped.TheLemon wrote:This is all true. Is this a gooped circuit as well?Greg_G wrote:Very likely a similar design with different voicing I'd say.

That's ashame as I'd really like to know what is going on inside the Model H and EGDM. Its always very interesting to see what Bjorn does to get a certain effect.Greg_G wrote:AFAIK all the hand built BJF pedals are gooped.TheLemon wrote:This is all true.

Please, if you would be truly interested in this you would spend time breadboarding the Dyna Red/Honey Bee schematics and playing with parts. Or better even, the Rat schematic: trying equivalent opamps, other tonestacks, removing the buffers, that kind of stuff...TheLemon wrote:That's a shame as I'd really like to know what is going on inside the Model H and EGDM.

Yes, experimenting without actually knowing what you're doing can really be educational. I mean that, truly... So go for it!TheLemon wrote:Its always very interesting to see what Bjorn does to get a certain effect.

I think Bjorn is referring to this: http://acapella.harmony-central.com/sho ... ?t=2397966IvIark wrote:No one in this thread has spoken about cloning and selling your designs Bjorn, you're almost trying to read something into it that doesn't exist. Unfortunately it's your own policy of gooping that piques curiosity.
