Just wrapped this GPCB ParaMix up today. Built for my brother to use in his bass and electric cello pedalboard. He was looking for a way blend in his heavily effected sounds but retain the fundamental bass and transient. This circuit fits the bill and can do a few more cool signal routing tricks.
Build docs list 200 nF caps for guitar with recommendation to increase for bass use. I used 680 nF to let plenty of low end through. Tayda Metallic Champagne Gold enclosure because as a teenager I used to drive a Volvo station wagon in the same color and we used to drive around listening to all kinds of obnoxious music.
Pretty easy build, required specific always closed mono jacks for the insert loop. I used a bi-color LED, first 2 I tried were duds finally got it lit up with the third. I need to either remember to test those before I solder or not buy the cheapest ones I see on Amazon. Maybe both.
