Fuzz & Negative Ground

Postby FausterCraster » 16 Apr 2017, 21:12

Hi,
the idea is to build the Dallas Fuzz using PNP transistor and negative ground.

Knowledge base : http://www.muzique.com/lab/fuzzface.htm

I bread board this circuit and it works, but I'm wondering
if I did the right thing and I'm close to the orignal sound
or I'm just building another variant of fuzz...

Note:
R3 has been rised fron 220R to 6K8 in order to have more output volume
R4 has been set in order to have 4,5V on the collector of T2 (measured resistence : 200R approx)

I've used 2 Ac128 (T1 hfe70 and T2 hfe 120)
any comment to this circuit is appreciated.
TX
