Hello
I am willing to make a stereo in, stereo out pedal (for drum machines and mix buss processing).
I am wondering how to make the wiring in order to get one single power supply, proper grounding wiring, and a single bypass switch (with led, if possible).
Of course, i have already searched quite a lot some infos, but most of the advices i can find are for mono in / stereo out pedals (like some chorus, for instance).

So here are the questions I have :

1- POWERING IT
I have read about the...

Hey all,
I'm brand new to this forum so I hope this question isn't out of place... I didn't see a more appropriate place :?

I had this weird thought while I was in the shower the other day. I want to make a multi-effects pedal that has a digital interface, but analog effects. So essentially, it would be multiple analog effects circuits built into one enclosure that all can be controlled digitally. I'd have a microcontroller using digital potentiometers to control all of the tone/volume/etc...

So I've built a pedal with two slightly different Germanium boosters in it.

One is a Rangemaster style treble booster that's a bit smoother and boosts some mids too,
the other is a straight full boost that gets into slightly fuzzy territory when cranked.

Breadboarded them both up to sort out part values etc, then built up vero board versions.
When built they tested fine in my test board unit, everything worked.

As soon as I built them into the pedal with switching etc, all of a sudden I'm...

I'm currently looking for a multi-effect that would allow me to have a drumbeat background that is controllable by footswitch (allowing drum roles, intros, endings and pauses etc). I'm not so interested in a programmable drumbeat, just something to go along with and at the tap of a foot I can stop\start. Does anything like this exist? And if so where do I find it?

thanks

I'm planning to build two pedals in one enclosure, and have a question about simplifying the power decoupling.

This is going to be a dual-Timmy, but I don't think the specific circuit makes much difference for my question; it's a dual-opamp overdrive.

The Timmy power supply is something like this:

V+ (9V) goes to the dual opamp; Vref (~4.95V) is used elsewhere in the circuit.

I want to add the 100-ohm + 220uF filtering as described by bajaman here:

I know I could add that completely...

My friend asked me to make him a rack unit containing a Sansamp bass preamp (my choice is BD21 lite , and a good compressor (like a THAT4301 based one ). Since it's going to be a rack unit I can power the preamp from something bigger than 9V battery. However, problem is that THAT compressors use +/-12V supplies, and the Bass Driver uses single-rail supply. What's the best option of connecting them? Should I simply power the preamp from one rail of a dual-rail supply? (I suppose not, because of...

I'm new to building pedals. I've built 2 Fuzz pedals. 1 is a BC108 Fuzz Face, the other a NKT275. I'd like to put them in one box. Have a on/off switch, but then another footswitch that just switches between the 2 circuits. I don't really want to be able to turn them both on at the same time.

How would I wire the switches? Anyone have a layout/diagram?

Thanks!

Now then lads,

Just had one of those lightbulb moments. Trying to cram a bunch pedals and a power supply on a shelf in my rack might not be such a brilliant plan after all. The enclosures take up a lot of room with all the space they need for batteries and footswitches, features that will be useless to me once I get everything hooked up. So instead of that, I might as well buy a rack-mountable enclosure to rehouse the effects I already have and don't bother with enclosures for the ones I...

Hello All,

I am planning to build 4 effects in 1 box (OD>Comp>Delay>Disto) with one input and one output. I am concerned about the loss of signal when all 4 effects will be switch on.

Would anyone advice me to build as simple Jfet buffer between each effects? or to add a clean boost at the end of the chain?

Thanks

Hi, I was wondering if anybody would have any idea on how to get one effect to switch off or bypass when another is switched on? Let me explain... I have built a stomp with 1 overdrive and 2 separate distortion pedals in it. It goes like this: (OD - Dist1 - Dist2) what I am wanting to do is when you switch from one distortion to the other I want it to turn the other one off and visa versa.. Rather than turning one off and then truning the other one on, just toggle between the two. Any diagrams...

Hi guys!

I've been thinking about this idea about putting all of my stompboxes into one custom-made enclosure. I think I've got most of it figured out, but I'm having a problem regarding the switches.

You see, most of my pedals use mechanichal footswitches, and that's great and everything. Unfortunately, a few are also Boss pedals using momentary switches and, I guess, some sorta IC (flip-flops?). I'd like to use mechanichal 3pdt switches for all effects, though. Has anyone else tried this...

I've put together a twin version of a 'Great Destroyer', utilising both sides of the chip. it's effectively two pedals in one box, each TGD having it's own 3pdt footswitch wired as true bypass with grounded input (as detailed at GGG).

what i wanted to do, which sounded so simple in my head, was add an overall master volume to this monstrous device, as each TGD churns out a mammoth amount of signal, and the volume control on each one really makes a difference to the oscillation, not just...

i was wondering if there was a diagram floating around that would help me build an effects loop controlled by a 3pdt into any stompbox. thanks in advance!!

I wanna put an OD and a Boost into one enclosure and then be able to use a a toggle switch to choose the order. In other words I want the option of having the OD go into the boost or vice versa.

Thanks in advance.

if the answer to this is already posted somewhere, i apologize - i did search but all i found were wiring diagrams for two fx in series.

i'm looking to wire two fx in one box, have ability to bypass both, and toggle between the two fx when they are engaged- i think the way to do it is to have one footswitch be the overall on/off (on/bypass) switch and the other be either/or , i.e., either effect one or two. i was looking to have footswitch one have an indicator led (on for engaged and off for...

Here's what I'm looking to do: Build two effects into one box with a little extra flexibility. For simplicity's sake, let's call each one effect A and effect B. I plan to have regular bypass switching, but then I want to have a toggle switch that allows me to choose between these options:
Only effect A
Effect A into effect B
Only effect B
If anyone can lead me to a layout of how to do this, that would be incredible!

Are there any rules as to getting them hooked up?
I'm happy doing single-box setups but recently I've had an urge to squeeze 3 distinct fuzzes into one enclosure. One of them will possibly be a positive ground circuit.
Apart from a separate power supply for that particular circuit, does this affect anything in regards to grounding?

Star ground perhaps? Confused am I... :oops:

Hi There,

an older idea that i had is grown up again, as i das the Fooltone gt500..

I Build a 2Channel Pedal some time ago, based on two Overdrive Circuits, where You can change between Circuit 1 and 2 (one Footswitch to Bypass the Pedal and one Footswitch for changing Channel...)

Another Idea was the Feature to take another Switch (not Footswitch) to make the 2nd Footswitch a different funktion
= one position of the Switch lets the Channel Footswitch change between Ch1 and Ch2
= 2nd...

I recieved this from a helpful gentleman named Димитър Димитров ---- Measuring of germanium transistors with digital multi-meter may be very inaccurate due to several reasons. Our engineer Mr. Plamen Vasev (dpebay@abv.bg) has invented a new method to check quality of germanium transistors via two measurements of the base current. With this we calculate the gain and also can conclude for what the measured transistor can be best used. 1. The leakage current Icbo is measured first. 2. Then the...
