A quick question: i need a robote delay with FX loop so only the repeats would get affected by the effects that would be placed in loop.
Schematic:
Where do you think that would be better to add it (according to my thinking): after the 1uF cap from the level pot (100K-b lower right corner of the schematic) and before 33k resistor (maybe adding a lower value resistor ... like 15-24k?
Here's one that apparantley has that all allusive and sweet Tube sound. Seems interesting enough. If you build it please let me know what its like. There is a full write up on how they achieve this so i will let all of you be the judge. Please enjoy and have fun!
so i set out to debug the liberal komrade with boost pedal i abandoned about 6 months ago, and got it working.
i'd made some mistakes on the vero and pulled it, and was determined to make it work, and did.
couldn't get the boost to work tho... i'd tried making a pnp version of the omega boost dino turned me on to for the suzy q project, but it didn't work.
since i'd fixed the fuzz, i was determined to make the boost part of the vero work, too... so i looked at simple boosts, and tried a few...
Hey guys ... i know that this is not an original idea but, i come in front of you with this: A very good friend of mine (a very good bass player) is never very pleased about any distortion pedal that he used, he would like to cut there to boost on the other part ... to have distortion only on mids or ... a little bit on low freq. and so on (i guess you know the type Smiley) - artist type without any idea about technical matters).
So ... i imagine this - split the signal in 4, have an EQ on...
Press and hold the switch to reset, ramp up, and finally hold the control voltage. Higher CV=longer delay. Some of the values are altered to make it look better in the sim. More appropriate values shown in the image below. I have them this way in the sim because it's dreadfully slow to watch the circuit operation at normal speeds.
There are plenty of other ways of doing this, sure... but there's something satisfying about using the PT2399 itself to...
I always build my stomp boxes with the power connector at the top end (furthest away from the player) - but I notice quite a lot of pedals have the power connector on the side, usually next to the input jack.
Is there a distinct benefit in doing this (other than having a shorter distance for the power switching) over the inconvenience of having two plugs so close to each other and possibly having longer power distribution cables on your board ?
Ive been having a lot of fun with Tim escobedo's circuit snippets, my favorites so far are harmonic jerkulator and punch in face . Can anyone help point out more circuits like this? In particular I'm looking for designs with low current draw and using silicon transistors not op amps. Or if anyone has any input about successfully adapting germanium fuzz designs for silicon transistors I'd really lie to hear what you have to say! Bonus points for designs that are very touch sensitive, or wave...
In my relentless pursuit of improving things I stumbled over the Boomstick (box of rock clone).
Mr Z. Vex says somewhere, that the class-A biased mosfets the BOR (and all its derivates and ancestors like the SHO) produce even harmonics.
As true as this may be, the B170´s chop off the sinewave brutally, a blant square wave generator.
I also fail to hear the often quoted touch sensitivity of this circuit. I do not believe there can be much done about that. There is nothing to tweak this.
(Note:...
all germanium, from hint of dirt to fuzzy goodness.
here ya go, the venerable kay 704 guitar amp adapted as a fuzz.
link to schematics/vero at the ultimate guitar site are in the video description if ya diggit.
An interesting little twist I stumbled across: I was messing about breadboarding a fuzz circuit using the input Q1 from the wampler velvet fuzz spliced with the Q2/3 rear-end of the skreddy lunar module using all 2N5089s. I was expecting a roaring, filthy overblown fuzz, and was pleasantly surprised at the lower gain sound I got. I had started to tinker with some values when I realised I had inadvertently installed the Q1 transistor backwards (i.e. with collector and emitter flipped). I put Q1...
i discovered they fucked this circuit up... or at least i believe they did.
i discovered the swell control was what made this pedal sound like dog doo.
info, to the best of my ability to explain it, here:
imho, this thing sounds freaking great now. no more wimpy fuzz with huge useless gain boost.
the fuzz is nice and thick, you can turn it from kinda...
I have a Super Bassman head and a Meatsmoke Preamp pedal. I want to run the Meatsmoke directly into the Bassman poweramp, bypassing the Bassman pre, but I'd like to be able to switch between the two. So basically my chain is:
Guitar > bunch of pedals > BassmanPre-or-Meatsmoke > bunch of pedals > Power Amp In
I don't need parallel/blending, nor do I *think* I need a buffer. An LED indicator is a nice to have but not a requirement... if I do have one, I'll have to feed it 18V because...
It's a good project on its own, but I did some extensive testing with alternate op amps in each position and have some notes to share.
There are two op amps, IC1 is a dual op amp used as an input buffer and then as a boost. IC2 is the clipping op amp, and is a single op amp.
For IC1 I settled on the TL072 after testing the JRC4558 (stock), LM358 and LM833.
* The LM833 sounded dull, likely owing to its low input impedance. It would likely have been...
JIMIPHOTONSTONEBLASTERMKIIverified.PNG hey guys, i revisited my toneblaster project last nite, and thought i'd share what has become a very groovy pedal.
i always thought it was too tame sounding for a tonebender type fuzz...was more like a compressor with a hint of dirt, it could overload an amp, but it wasn't right.
so last nite i opened it up, discovered the attack control had been disconnected...ooops...thought it seemed real subtle..
while i was at it, i discovered the ticket to tone...
naaaaaah..... aye and aye be gettin right lately, this is one of my dumber ideas, mon...

(the twisted tran-sister quick change socket, if ya don't get 1337)
i've done this on several fuzzes and things now... i am a germanium FREAK. screw that silicon stuff. it's not the same.
played thru my bro mike's rig last nite, all si and was startled by the differences in response of the wah and fuzz in particular... it is...
what is it? well, recently an audio designs fuzzound was on evilbay with some pics... so me and CRR decided to see what we could make of it.
he's still working out the original, i've already boxed my version, which i call the fuzzy balls boost based on the labeling of the knobs.
very gated, buzzy in your face fuzz, kinda reminiscent of both buzz boxes and univox superfuzzes. cleans up decently at some settings via guitar knob.
inSANEly loud.
Long time no talk around here, as i had a lot to fix in my life :roll: i have a new project on bench and that is a MIDI switcher. This is build for a customer of mine, witch had a very specific request:
- should change amp channels
- should change a bunch of pedals in amp's FX loop
- should use note on/off to change the configuration as he sing a song. And this is accomplished with a click-track (from a computer with midi interface) witch will send me note on/off events, and so the...
Anyone have info on this one ? Looks like it could be a mod Dr. Boogey without the mid control from the pcb shot and sound clip. :hmmm: Of course the sound clips don't match 100% but through my crappy Dell speakers they sound pretty close with the exception of a little EQ tweaking on each pedal. Tried the search and didn't find anything here.
Hello everyone,
I finally dug up the book with this one in it. It's an old comparator-based fuzz designed by Craig Anderton. It was originally published in Popular Electronics, July 1972 in an article entitled, Build the Optimum Fuzz Adapter .
I built one of these in high school and it was probably the second thing I ever built. It gets a big buzzy square wave sound that reminds me of the sort of tones you hear on Siamese Dream . One thing to note is the fact that the negative terminal of the...
I have this looper pedal which I want to use both in FRONT of my FX chain and in the BACK of my FX chain.
I was wondering if a pedal already exists that can do this? If so, please point me to it, would be interesting.
(I don't think you can do this with a line selector pedal right?).
Anyway, this should be pretty easy to make myself. But I'm not that great in electronics, so I have some basic questions:
- I guess you don't have to switch the grounds of the FX right? Just the signal...
I had a bit of time this weekend, and a strong desire to breadboard, so decided to see if I could a make BMP I actually liked (as I am wont to do every few months).
I really like the simplicity of the clipping diodes and the idiot-proof biasing arrangement of the big muff, but I seriously dislike the tonestack and the way the pedal only sounds really good when the sustain is cranked (and therefore too distorted).
Probably a fool's errand, but I was aiming for a more versatile high gain...
