The Cave Dweller 2015is a total re-design of the Cave Dweller project from 2012.
While the original Cave Dweller was a simple and colorful sounding delay it had a few drawbacks;
it was pretty lo-fi, and darkened the dry guitar tone somewhat. This was due to the limitation of using only the PT2399 for both dry signal and delay signal processing. The objectives for the re-design were to improve the quality of delay and dry guitar signal without requiring as many parts as a full-fledged delay circuit such as the MBP ZP Micro. This is accomplished by introducing a new input stage for dry signal processing and also by adding additional filtering to the delay signal. The result remains fairly low in parts count without compromising on the delay tone.
