Pas-Isel is Welsh for Low Pass, handy that when this is a Eurorack filter module.

Dwyfor Tech are a new company who have taken inspiration from what has been said to be a “forgettable” Buchla filter circuit, smashed that into a Korg MS-50 diode ring for a resonance path and masses of lovely guitar pedal style overdrive and they’ve made that a Eurorack filter with bags of character, and a different tone and circuit design (it’s really multiple high shelf EQs).

“3 Patches with … ” is a video series where I pull focus on just 3 things with a piece of gear, set of functions or techniques. More of these to come alongside the larger in depth demos in the future.
