Here's another Lovepedal for you. What's in this one I wonder? Well, IVIark (of the great tagboardeffects.blogspot.com) has provided a trace and schematic with the help of rmrosa. Firstly lets see the Lovepedal description;
"Your quest for the ultimate Fuzz ends here.
Lots of players use it like an OD pedal or full on fuzz, even distortion.. Roll back the guitar's volume and you're left with a lively shimmer atop your guitar and amp's identity. Amazingly, this happens to an appropriate degree throughout the pedal's range, and without the annoyingly excessive boost in volume that many overdrive pedals generate. And, yes, it's dead quiet.
The Fuzzmaster is a VERY sweet, smooth, silicon transistor based, fuzz that is warm, organic and sings with sustain. While it has an UN-mistakable vintage tendency, it also has a unique voice. Vintage Fuzz Face tonal heaven and everything in between, even tweed amp tones are in there."
And we're going to need a nice ProGuitarShop demo too;
So it sounds good enough, now lets have a look at it's innards - here's the schematic;
So it's the standard Fuzz Face circuit with a few tweaks - firstly the Blend cap which controls the bass level (and overall fatness) and slightly altered gain control network. The main change is the way the circuit utilizes PNP transistors but is still wired as a standard negative ground circuit (so it doesn't require it's own isolated power supply!). It's a clever trick that has been around for a while now.
Note, rmrosa (who provided the circuit to trace from) noted down these voltages from the original:
1 - 1.46V
2 - 6.62v
3 - 7.24V
1 - 6.62V
2 - 7.48V
3 - 7.93V"
