Nice little dirt circuit:

wizard fountain gain pot.jpg

The twist control is odd but interesting. At absolute minimum it produces a gated, octave-up, sort of poorly superfuzz sound. There's a volume bump as you start to turn it up, and it becomes a much more polite kind of dirt: It then becomes gradually gainier/fuzzier as you dial up to max.

Boosting the input gain by bypassing Q1's emitter resistor with a large electro gives a wider range of sounds, and the minimum twist madness sound can...

I got a one of these pedals for cheap on ebay to try a rehouse (first time) and true bypass(also first time). So Im waiting on the parts to come in for the true bypass but I had an idea for a mod. It has a spst switch to turn the octave on or off; my question is can I replace that with a pot to blend the octave in and out?

I recently acquired one of these and I've read that they can be modded to address the volume drop issue. One post I found suggested swapping a resistor but, I couldn't find that resistor on the board. Can anyone help me out?

Thanks!

last night i surfed the site and all of his hard to get transistors were gone...
he is out of stock on all of them ! :o
question is... has he been that before or is this the end ? :shock:

Hi mates... I bout a 4tet of matched trannies for this build..
The seller sent me the 2N5952 set with this note attached:
Id 2,4 mA
Vp 6,5 V
Since im running low on trannies sockets, i soldered them on the pcb raw.
Am i in the ballpark for a good sounding Phase90?
Swooosh

hi, i want to make a ABY switcher, but i want also a mixer output, can it be done?? maybe mixing the signal with an op amp???

slo avendger\hotrod or jcm800 with depth mod !
1.5 mm steel , 4xM5 screw, powder coating
60$ + shipping
very solid construction!)
only chassis!

Here is another one schematic for comparison and workbench if someone wants
to get 808-steroids sound. 8)

since the cheapest way to ship to europe now is the flat rate priority box, it is the best deal to ship 3 wah shells in one box. total shipping is 59, so total is only 40 shipped per wah shell.
these are near new dunlops, - two will be near new with almost no chips, the 3rd is 'good' condition with only minor chips. i can also sub one or two chinese vox shells ( one v845 , one v847a). each shell is complete with rack gear, bottom plate, non- original feet/screws and rubber treadle, fully...

i just bought this one:

with free shipping :)

this seller has more pictures of same product, but higher price:

i will use it for testin hFE and ICEO on my transistors.

i hope it will do the job för circa 50 bucks only :)

this one was even cheaper but i dont know if it will do the ICEO :S :

i will come back with a short review...

I've got here a 1971 Fender Blender. Sounds rad.

So, I'm poking around in here and have found a few things differing from the original Fender schematic

As opposed to 5 2N3391, I'm seeing 2X 2N3565 and 3X marked 121-433 7111, the manufacturer's logo is tough to make out, maybe Nat Semi?

Any of y'all know anything of these 121-433 trannies? I assume 7111 is a date code.

And the diodes... as opposed to glass bodied 1N276 GE's, I've got these white, solid bodied little jammies marked only 920...

I had off work last Monday due to snow, and came up with the idea of tossing together a quick overdrive to pass the time. And because I'm not good at doing simple things like that, I instead ended up breadboarding and working on a new design all week. ::)

The Snow Day OD is a FET- and MOSFET-based amp simulation overdrive running on 18V that includes a switchable miniature compressor circuit and soft clipping in a power tube section. It goes from glassy mostly clean to either open or slightly...

Hello - i approached Zvex Seek Trem and TREMORAMA but they seem a bit overpriced?

Since the zvex Super series came in what's a good price on those pedals?
I mean the price that would make them gone from listing in about a week more or less.
Here - they are listed Seek Trem for 395.7528 US$ and 362.7734 US$ for tremorama.

hotpotz2 used $12 each or 2 for $20, these came out of donor wahs for my custom builds. used is no problem as they virtually do not wear out ( plastic trace construction). for an additional $5, will substitute my larger 16 tooth gear for less drastic kink in sweep. add $2 for postage in the US, $9 outside US,regardless of quantity.

beat up dunlop wah shell - complete with blocked off batt cover on bottom plate, feet w screws, rack gear/ tensioner/
full shell minus pcb and harness. moderate...

HI, im selling a dry film solder mask resist for good professional finish in pcb, this its high quality Duponts 3mil thickness mask, easy to use and amazing finish,

im selling it for 8 USD per foot long and 16 Width, shiping its from Honduras using postal service, also i can use fedex or dhl to send to USA, but thats an exprensive service.

this its a tutorial

also a complete thecnical guide from Dupont

hi

i have just built a bk butler clone (
the problem is that pedal sounds very muddy. I know that TD is a muddy pedal, but this one is extremely muddy (including low gain settings). Gilmour use it as a booster, what is not possible with mine.
all components are correct value, all soldering OK, tried different tube-no success.
is there any idea what could be a problem and where to start?

thanks in advance

Hey all, I'm selling my Peak Atlas DCA55 on eBay.
There aren't too many pedal builders out there so I'm trying to spread the word.
Product info and specs here..

It's in perfect working condition. No scratches, no issues.
Includes original owners manual.

$0.99 starting bid, no reserve. Reasonable shipping costs.
It goes on sale tonight at 7pm (Central time), auction goes for 7 days.
If you know anyone that may be interested, please let them know. Thank you.

anyone knows where in the usa , i can find high quality know small ones , standard 6mm shaft

The other thread is already pretty heavy, so I'm creating this thread for reference.

This addresses both clone PCB's that UKToecutter produced. Version 1 is the orange board, and version 2 is the blue board. I realize that everyone that bought the first version was subsequently provided a second version, due to errors. Although the second version had two small errors as well, I decided to list all the corrections, for both boards. At least that way, if one wishes, they may recuperate the V.1...

:?: I'm planning on building two completely independent circuits in one box with separate I/O for each but I need it on one master switch and a master LED so both go on or bypass at the same time. Am I missing something or is a Millenium Bypass for each circuit with a 4PDT stomp switch and LED +/- for each bypass board tied together is the only way to do this? thanks!! :thumbsup

hi guys,

I am building a 1776 Multiplex Delay... quite big build, but believe me its worth the effort.
The pedal sounds really good, definitely all I would ever need from a delay pedal.

Now when it works it's great. My problem is that after couple of minutes it goes into screaming frenzy, which seams to be coming from the second head delay chip... at least it is effected only by the knob that is controlling the speed of 2nd head.It;s triggered by higher signal on the input - like hitting...

Hi everybody
Marshall JH-1 is a cheap but I think interesting stomp box, with a lot of pots, especially for tone tweaking.
The gain is way to high for my taste, so I tried to find ideas to make It sound more crunchy and less mushy ...
Attached is the schematic and the mods I did.

It is fairly simple : 2 resistors to change, leds to remove, new diodes and a switch.

Resistor R10 is set to 10K instead of 2.2 K, thus changing gain range (first stage of op amp)
Then R11 is set to 140 K instead of...

Hi, looking around for switch solutions... I found these stomp with nice (to me) switch ..looks like an actuators

Anybody knows where to find such particolar model ?

Okay, so the Boss Hyper Fuzz FZ-2 is pretty rare. It's really just a Univox Superfuzz with a much fancier tone stack though.

I started out thinking okay, I'll just isolate the EQ section for Mode 2, since that's the mode Electric Wizard used and that's the only thing I really want from the FZ-2, and I'll bake that into a Superfuzz box. Except the Superfuzz layout I used is a bit gluttonous on internal volume, and now I'd be adding another couple of knobs to the enclosure and it was beginning...

I wish to true bypass this wah as when its in the chain and not on you loss a heck of alot of top end, thing is iv'e only ever true by passed a pedal when the input & output jacks are not soldered to the board as they they are in this ibanez pedal. would it be a case of some extra jumpers on the 3PDT switch
