Merry Christmas to everyone! Hope everyone has plenty of time to do some soldering over the holidays.
Grind Customs has had a lot of really great projects, but their website has been out of business for a long time and it seems that they are gone for good. Their De Profundis delay was very much appreciated and they offered an additional modulation card, the PLFO. Originals had the EQ as a trimmer, but let’s go broke and have it external. The delay card fits in a 1590B, but with the modulation add-on I would recommend using a 125B. Here is the original De Profundis and PLFO Create documents for reference.
