Resonant Lopass Gate PCB's (New Batch 4/29/12)

I kind of get what TekniK is getting at - by "comb filter" he means the karplus-strong-pluck type effect you can get by turning up the resonance on a comb filter and feeding a transient sound into it. On a vactrol LPG you get a similar effect by feeding a sustaining sound through it and hitting it with a transient CV. Either way, the efffect is somewhat like a finger plucking a string. The Plan B LPG does do this effect very well. I don't know what the actual answer to the question is, mind.

I used to think the slower the vactrol the better for those plucky sounds. Could be wrong or a matter of taste.

However, the Borg 2 has very fast vatrols and can do plucky sounds but I thought my Fonik LPG better in this regard. Unfortunately by now I've killed my Fonik LPG so I've no chance to do a direct comparison at this moment.

Hi gang,

The PCB's arrived today. I am currently sorting them per the orders and making up shipping labels for each. I will ship them in two batches (USA Domestic & International). There are around 100 orders so it will likely take the full week I anticipated to get them packaged and out in the post. Stay with me, your order will ship by next Monday at the latest. My wife will help me write the customs slips for the International ones to speed the process. Boy, the post office is going to loath my arrival with all these little packages to weight and process (HA!).

See below for the PCB pictures. The silk screen and solder mask came out great. The RoHS Lead-Free process means they are whitish instead of silver like tin/lead boards... and I tested them to make sure the finish solders easily and it does. The spacing for pots came out very nicely if I do say so myself and is fully compatible with Spectrol/Vishay 148/149, 248/249, Alpha 16mm PCB type pots and Bourns 91 series among many others. Enjoy the pics folks! Shipping emails will come soon!

Thomas

Hello, if it turns out that any pcb's are left over, or become available, i'd like to put my name down for 2 or 4, please. Thanks.

Ladies and Gentlemen,

All shipments are being sent on the same day. I will be at the post office at 9:00am tomorrow, on Saturday, November 8th to mail all the packages to the world... and let me tell you there are a lot of them. You just don't know how much work this is going to take until you have all the shipments packaged, the customs slips written, and the packaging all sealed up! So, be on the look out for brown craft envelopes as shown in the picture below. I ran out of them so two were sent in white ones and a few larger orders were sent in standard orange paper bubble-envelopes. Please email me when your shipment arrives. It could take up to 2-3 weeks for some of the far regions. Just remember I am shipping from Los Angeles area, California when trying to figure out how long you should expect. Thanks again for your support of this project!

As someone who ships a lot from my own online store, I feel your pain! Thanks so much again for this, and I look forward to receiving my boards!
well done

Saturday "Post Shipping" update:

I just got back from the post office. A kind lady named "Joulee" helped me to ship 112 packages total over the course of 1 hour. All orders have been filled and processed. Please email me when your order arrives. All International should take 5-10 business days to get to you.

I will make sure to update the PCB layout on the docs packet this weekend. All the parts are the same, but the traces got switched around a bit for the resonance pot. I can't wait to see the various builds people put together from this!
