Fuzz & Negative Ground

Postby FausterCraster » 16 Apr 2017, 21:12

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...

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.
