hey how's everybody?
last night i decided to take the big leap and get into diylc for the first time. it is my first attempt at cobbling anything together on my own, as well as the first time attempting a layout of any sort. i figured i might as well take a few simple circuit snippets that i have previously built and cut and paste them together. the basis for this design is the Triggered Square Wave Fuzz by Craig Anderton that Soulsonic posted a while back and Royaltoots posted a vero layout for. i really dig the freaky squarewave action that this simple circuit puts out. when i built it i removed the last resistor and back to back electrolytic output caps. this made it extremely loud but the square got even more pronounced.
an idea came about when messing around with this thing and my Time Machine Boost. i liked what was going on when the comparator fuzz was actually driving the input of the boost. the square got even bigger and meaner as it got compressed and then boosted. that got me thinking about how i could take this thing totally over the edge, so i got out my Bazz Fuss circuit(a squarepusher in it's own right) and slapped that at the input. what came out was pure squarewave armageddon! big thick chewy squarewave goodness with lots of rich harmonics. it gates when you aren't playing(not to much to get in the way), and sustains forever then eventually starts into feedback and deconstructing itself in the most peculiar and wonderfully disturbing ways.
the the funky thing is, is that the anderton circuit uses a floating ground. so i know i probably don't have the grounds hooked up right in the layout. i don't even know if it is possible to run this thing off of of a common 9v with the other circuits. i guess if i have to a can give it it's own separate 9v, but i'd rather not. :wink: i'm not above putting on a big ol power switch on the face as well. (2 batteries=dpdt?)
in the layout, i left in the electrolytics(i figured it could use them for coupling- whether they stay or get
replaced we'll see.) i figure i will probably need some sort of power conditioning, and there are multiple pots that i just kind of slapped on there without much double checking as well as spots for seperate switching in and out of the circuits. values have been left blank for now. finally i decided to us Gus's NPN boost for the final stage with possibly a germanium transistor.
any advice or criticisms from the scary brainiacs in this forum would be more than appreciated.
