This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.
Happy Fuzz Friday! Here's the Spaceman Effects Titan II fuzz, traced by Dino (Digi2T). I simplified the polarity protection, removing the BS250 in place of a simpler 1N5817 diode. Transistors need to be pretty low gain—under 200 hFE. Should be an easy fit for a 1590B.
Google tells me: "Ferrite beads feature a hollow cylinder or a bead made of ferrite and are suitable for eliminating high-frequency EMI noise on any circuit design. They are widely used in commonly used electronic devices, including cell phones, computer and laptops, TV tuners, audio players, DVDs, and gaming systems, to keep the power lines noise free."
That's a pretty concise description, without getting too technical. I'm sure you've seen them on the ends of some computer cables.
I built it based on a layout from other forum . Sounds very good but gets an oscillation at the last 10-20% of the fuzz pot. I believe it must be an issue with the layout... small caps here and there did not help. So how its gonna be with this layout...any info would save me a lot of /de/soldering... thanks
Spaceman is kinda obsessed with ferrite beads, puts them everywhere, even where they are not needed.
ReplyDeleteWhat is a ferrite bead and whats it used for?

Yeah... not as common inside of pedal builds.
Recuerdo mí rangeblaster... Esto podría bajar ese humm tan odioso...
DeleteI see a lot of different ones but they all range in resistance. Which one is needed in this build?
ReplyDeleteRegarding which part? RE: Ferrite beads you could literally just put a jumper in place, they likely don't do much most of the time.
DeleteVERIFIED and it sounds great!
ReplyDeleteWhat transistor do you use man?
Deleteu sed 2N2222A's with 180-190hfe.
Deletesweet i got like 200 of those little shis. awesome
DeleteVERIFIED +
ReplyDeletesounds great! Transistors i use: 2x of 2n2222 (hFe=180), 1x of 2n3904 (hFE=190)
verified too, used Q1,q2 3904,Q3-2n2222(hfe 340), changed Q1 2n 2222 (hfe 320), good sound. did not use any ferrite beads.
ReplyDeleteDo you guys get an oscillation at higher gain settings?

ReplyDeletethanks
hi geeks,
ReplyDeletewould you explain the way this tone control with the 2 caps wokrs.... is it hi pass/low pass thing or just blending...
thanks in advance!
Sounds great. Definitely building this with 2n2222s
ReplyDeletenice with Q1,Q2 germanium mp38a, Q3-2n2222a
