Devi Ever Ruiner

Another brutal fuzz machine from Devi, and sounds great on bass and guitar. Pretty straight forward design–two cascaded transistor amplifier stages with a pre-gain control (intensity) and standard volume control. Pots are board mounted and it shouldn't take all that long to throw together.

    It works! LOTS of (too much) boost and with the drive past one or two, its more of a noisemaker. Dunno, maybe I'll try a pair of transistors with less juice.

      Thanks for verifying!

      I have to agree. Tried it now with 2N3904's and its a lot more manageable. Also seems a lot closer to the demo vids. Loaded with the MPSA18's it seems like there is little gain range. I also upped the intensity pot to 500KB. More range in general.

    Any link to a schematic you worked from? I know its a pretty simple circuit. Just have some conflicting capacitor values with the only schemo I can find of this one. The only difference in values is input and output capacitors are 1uF instead of 100nF. Did you modify the values? I understand why you would, would just like to know if 100nF's are found in the original version?

      I laid it out based off of this vero layout.

    Used 2 x BC337 Transistors and sounds well synthy. Not seen the demos online yet but good project to experiment with.

    Thanks

    Mine is behaving a little bit odd. It is quieter when the effect is engaged and the only thing I get is some farty sounds when I strum hard. Would that be misbiased transistors possibly?

      Yeah, probably biasing. Try adjusting the value of the 10k to the right of Q1 and the 10k to the right of Q2.

    I used 2N3904, sounds so cool and closeto the original (I have it), but there is a constant sinthy noise when I don't play, what can be?
    Thank you so much!!

    Omg, this is be the best sounding fuzz I've ever heard..simply must make it today!!

    May I ask, after the first stage isn't missing a 100nf to GND ?
