Nocenteli Magnalous Lunevibe

Stumbled across this design by Nocenteli on FSB and thought it was cool, so here you go. Mashup of the Tremulous Lune LFO and the audio path from the Magnavibe with a toggle to switch between tremolo and vibrato mode. I ended up putting the Fine control internally as a trimmer for 2 reasons: 1) In my experience with this kind of LFO it's not all that necessary, and 2) I miscounted the number of pots in this when I started layout it out and was too far in to start over. 😂 You can always wire it off-board if you prefer. Should fit nicely in a 1590B.

Nocentelli JFET Boost

Here's a recent design by Nocentelli. A single JFET stage into a Baxandall EQ stage with a BJT gain recovery stage. Originally designed with an opamp gain recovery stage and no gain control, Nocentelli redesigned it for a lower parts count and easier build. I added a trimmer to the JFET stage so it's easier to bias correctly. More info here on FSB.

Greaser Fuzz

Here's a cool little fuzz designed by Nocentelli over of FSB. It's based on the D*A*M GB-83, which is a silicon adaptation of the Tone Bender Mk. III (sans the tone control). Definitely worth building up. Here's the schematic for reference (you'll have to login to FSB to access).

MMR Fuzz

Here's another great design by Nocentelli for Fuzz Friday. It's a fairly simple 2-transistor design with a wide range of tones on tap. Pots are all board mounted and should fit in a 1590B just fine.

JFET Overdrive

I could have sworn I posted this back when I started this blog, but apparently not (hence the 'old school' pcb). It's another of Nocentelli's designs and somewhat similar to the Marvel Drive. Original schematic can be found on the FSB thread.

King Dubby Delay

Here's a cool delay designed by Nocentelli posted over on FSB. Here's what he had to say about it over there:

Here's a variation on the deep blue delay; two PT2399 chips and a current mirror delay pot give around 2200ms delay, although beyond 700ms gets pretty lo-fi. There are two points where a momentary SPST can be used: Either to briefly connect the input to the delay input on select phrases (dub mode), or to bypass the repeats feedback resistor for self-oscillation on demand.

Note: I've recently found out the capacitor going from Repeat 3 to Osc Sw2 is 22n.

Bikini Wax

Nocentelli's Bikini Wax is a shaved down Big Muff with the tone control and gain recovery stage removed. Play around with transistors and especially diodes to change the tone to your liking.

Update 3/16/15:
Since the layouts for the Green Russian Big Muff were derived from this one, and the Green Russian was missing a resistor from the power rail to the collector of Q3, I figured this one might be lacking that resistor as well. Sure enough, there was no 10k resistor where it should be. Updated the layout and should be good to go now.

Axial Fuzz

Here's a silicon Tone Bender type fuzz by Nocentelli from FSB. Just about any NPN silicon trannies will do... 2N2222, BC108, 2N3904, etc.
