There was no Build Your Own Community Pedal category, so if this should be in another sub-forum then by all means relocate it!

Here is the schematic for the Octophant, a pedal we threw together over at Harmony-Central's FX forum. It is similar to a fuzzrite but with 2n7000's. The octave up is from the push-me-pull-you. The boost circuit is a simple gain stage with an AC187. It isn't the most groundbreaking thing in the world, but it sounds cool and we had a ton of fun tweaking the design....

I accidentally posted the build report in the workbench section, so here's the link:

Hey guys,

I'm looking for a little help in finding the right components for the following fuzz face circuit:

I've been looking on Small Bear, but I don't think they have the right capacitors I'm looking for. I'm wanted to check to see as well if the following trimpot will be big enough to fit in the required space:

I was planning on using BC108 transistors and was wondering if anyone has used the Small Bear BC10x work-alike transistors. I've got plenty of resistors already but I was...

:scratch:

Hey guys, tonight I worked on my 3rd 1484, I replaced the power caps, added a 3 prong plug, electrolytic caps in the pre amp, and added a new mojotone output transformer and it has nothing but hum when I switch it on.

I've done 2 other 1484, one changing just the caps and adding a 3 prong plug, and the other I did the same thing as above but it worked just fine. I will post pictures tomorrow because i've been hard at it on this amp for hours and it not working is pretty much making me need...

Hi all. Hope I'm posting this in the right place. I'm wondering if anyone has tried building a hybrid of an Octavia with the octave section of the circuit taken from a FTM. I've been looking for a good versatile octave fuzz. I have a Devi Ever Godzilla that's going up on Ebay soon because it's just TOO crazy. Didn't like the sound of the Joyo Ultimate Octave (even after the mod presented on this forum), and from what I understand the Joyo is based on the GGG FTM as well. What I like about demos...

hello!!

Please excuse my english!, i'm writing from chile!

i'm starting this topic since it wasn't created yet!...searching at google found this pics!

I would like to know how the add ons of this pedal are made... as everybody knows its a refined tubescreamer with active tonestack... but in the simple version there is only bass and treble so here is the first question...

how we can add to the simple bb schematic a mid control?, it necessary must be an active circuit?

A second switch works...

Hi There,

I'm lucky enough to have an MN3005 and would really like to build an AquaPuss to MK1 specs.

Anyone have one to sell me?

Alternatively, I would also be open to having someone build me the pedal, minus the ICs. I like to focus more on playing rather than drilling holes in enclosures in my yard!

Kind regards,

John

Hey Just saw this. This is a pretty ambitious Kick-starter program but figured it should be viewed here so I post it.. I have no involvement with it..

can someone help me ? i live in brasil, and right here a original electro harmonix pulsar costs like 250 dollars, so i decided to make my own. i already did the andervol circuit to my volume pedal, and the bluesbreaker, but yesterday i decided to start de pulsar, and i read about the rate pot fix, and some other mods. so i did the fix on the pcb layout, and i put a 10k lin pot. the fx worked, but i think the rate is too fast, how can i lower the velocity of rate ? change the value of r14 works...

There is thread about older unit, but I want to make one with unit that has LED,and different circuit.....
fuzz is different, and wah section is standard ,but have FET input buffer and 100K instead 10K emiter to ground resistor R107 on pictures...

more to come.....

Hi,
i know that many topics were about Dr boogie transistor's ,but i had to open a new topic
My problem is that in my country (Croatia) the j201 is very rare and vvvvvvvvveeeeeeeeeeeerrrrrry expensive
I found the alternative in a form of a 2N5458 which costs much much less
So the question is what kind of sound will the 2N5458 produce,and which elements do i have to change on the pcb(source resistor,etc.....)

Also those with the expirience of experimetnig with other alternatives I ask of yout...

Hey! I didn't find any info or threads about this, so here goes:

I built a Ruby amp a while ago, and finally I got some sound out of it. Too bad the sound is constant BZZZZZZZZZZZ or HMMMMMMMMMMMMMMM , you know. Guitar signal doesn't go through at all. Is this just because of faulty grounding? I checked all the soldering joints and it was all right. Is the IC fried? Voltages on ic pins goes as follows:
1. 1.46
2. 0
3. 0
4. 0
5. 5.82
6. 12
7. 5.85
8. 1.46

Sooo yeah IC looks nasty. IC is JRC...

I thought I'd throw this up since I didn't get any hits here and I finally found the zine ( 101 Electronic Projects ) it's in. This thing was included in the 1972 edition, the 1973 edition and the 1974 edition (slightly renamed Fancy Guitar Fuzzbox ).

It uses a couple germanium pnp's

I cleaned up the schematic and breadboarded this a while ago

It was cool, but I didn't spend enough time to get it to the point where it was worth boxing.

So, I breaded it again. I used some standard...

Hello,

Can anybody in here help me with wiring a Neutrik NTL1 Isolation Transformer? I found this diagram on the web

As you can see there's a XLR jack used, but I want to use it with a regular mono jack. Am I right, that I just have to leave out Pin 2?

Kind regards,

Dominik

A google traveling looking for something I've forgoten now gave me this:

wich I have duplicated here, just in case:

A great, comprehensive reference book.

Regards,
Juanro

this was something i breadboarded up dicking around earlier...
i did a vero for it, but it's not verified yet, so if you built it, you're on your own,

probably been done, oh, 200,000 times, but it's new to me...

if someone else builds this, please let me know!! i will try and work up a schematic for it when i can.

nice fuzz...nothing spectacular, but ballsy! ;)

hi all,
i'm looking for some 16mm 50k pots, and up to now i only found the bourns - pots, that have higher bushings (ca 9mm)

but there are only 24mm ones.
any ideas?
thanks,
sonni

Hey everyone.
I am slowly digging into PCB designing, and now I've encountered a silly problem.. I'm designing a no offboard wiring PCB for a Ruby amp with the bassman mods, with the board size suited for a particular box. The fact is I have too much space there, therefore I don't really know what configuration will work the best. If I were limited by space I think there would be no problem. ;p
So here's my layout. It's kinda done, but I'm not sure about it.

What should I...

I've searched and can't seem to find how the level pot's value works with the EQ.
I want to mod my Boss HM2's tone at the High. At the moment the mids and highs are tied together with one 10kB tone pot.
They look like fixed bands like you would find in a regular EQ pedal, does that mean it gives +/-dB gain?
Was looking at splitting up the two with a concentric 100kB pot from either small bear or a cheap MT2 donor pedal.

Another thing i noticed with the pots, they are all parallel, and lowering...

Hello all

I've recently been looking into modding my cheap Belcat OVD 302 overdrive pedal to make it more bass friendly. I've been using Tube Screamer mods as a rough guide as it seems the Belcat is a really budget TS808 clone (though nothing seems to be set in stone). It seems Joyo have overtaken Belcat as the cheapo pedal of choice (I own a few), but I would like to make my Belcat more usable with my bass.

I've attached three images;

Hopefully from the three the more expert...

this is basically a silicon fuzzface with pn2222 's hfe about 200 modded with a 100k output pot, and a 10k bias trimmer. it's wired before but in series with a guitar pcb.com Transparent Over Drive Deluxe...both are completely independent of each other, and to my twisted ear are a great combo...hard to show what it can do without a blazin' amp...there's a red led on the overdrive, and a blue one on the fuzz...put 'em together, ya got purple...add me, and stuff gets hazy...so...

First off, long time lurker, first help request. I really appreciate the humongous amount of information here.
Now I have a box of pedals that either dont work, kinda work, or work and suck... And in it was this small stone, now in the past I've heard it phase, while experimenting with the wiring, so I know it works. But the butthole that had it previously hacked up the wiring. I haven't seen a wiring diagram for this model and was wondering if anybody could help.

Hey all:
I just bit the bullet and ordered a couple of GT313s from mother Russia. 3 will go into a Toecutter, and I think 3 more have Buzzaround written all over it. They're specified at 20-200hFE.
For those of you with GT313 experience, do they follow any trends gain-wise, or are they completely random, as most Ge transistors are?
I only bought 10, so I want to make the most out of what I've got. Thanks!
