Nobels FU-Z Fuzz

Happened to spot one on ebay for mere 250 usd. A bargain. For this layout, i omitted the buffers and electronic switching. 30K pot value may be hard to  source, so one could try 50k pots for all of them. Original unit has 2SC2240BL transistors which are low noise devices with BCE pinout and hFE range of 200-700. I think 2N5088, 2N5089, BC549 or BC550 with gains at 400-500 should do just fine. The transistor image is for 2N* devices, so mind the pinout and experiment.

    Nobels description: " Fuzz pedal designed to recreate the vintage sound of the early transistor amplifiers. Classic chainsaw fuzz sounds.

    Built one. Not bad. It is a nice mix of modern and vintage sounds with its slow attack and buzzing overall feel. Nothing too special, but nice. Might box this up one day... The 50K log pots for attack and tone work well. However, i'd recommend using 50K or 100K lin pot for the volume.
