Why do buffers make my fuzz suck? (Signal Fixer demo)

Why do buffers make my fuzz suck? Guitars have a fairly high output impedance, and the pickup/volume/tone pot circuit is actually pretty complex. Many fuzz circuits have a low input impedance that your guitar can't drive. The relationship between your pickups/volume/tone circuitry and the fuzz circuit is very interactive and creates signal loss particularly in the higher frequencies. This interaction can even make the output sound gated and velcro-y depending on your volume and tone settings. A buffer can drive the low input impedance of the fuzz circuit which effectively retains the high frequency content of your signal, and can kill the velcro-y goodness.
What is the signal fixer? The signal fixer is nothing new. It's passive circuit that is basically a modified version of the Jack Orman pickup simulator. There are fuzz pedals on the market that use a similar circuit which allow them to play nicely with buffers and non-true bypass effects (Earthquaker Devices Eruptor comes to mind). I built the signal fixer to allow me to move my fuzz pedals throughout my signal chain without killing the effect. Hell, even some active pickups can make fuzz pedals misbehave, and this solves the problem.

Hi man, how are you? do you sell them or have an schematic to share? thanks a lot! Excellent job!

[@bradthompsom2957]

Do you build these just for yourself? I didn’t see a link if they are for sale.

Hey, Brad! I mostly build for myself, friends, and recording studios in the area....been doing it about 20 years. I've put a few things on Reverb and eBay in the past, but there wasn't much demand since the pedal world is over saturated.

I put one of these in my Reverb store.

Awesome! I want to be able to move my fuzz to other spots in fx chain. Will build one of these if i can. Judging by the amount of people on forums seeking a solution for this, i cant believe there isnt more comments. Thanks for the vid. Cheers!
