2 Effects pedals in one box query.

Fuzzy-Train · December 21, 2006, 09:05:31 PM

Some of you may remember that I've built an Octavia clone, and a Fuzz Face clone. Well, I'm planning on making more in the near future, and I want to clear up some space in my effects chain and make it nice and neat. I was wondering how to go about installing the Fuzz Face, and Octavia in one box.

The way I want to do it, is to have 1 stomp switch to turn the octavia on/off, and 1 toggle switch to turn the Fuzz on/off. I won't be using any LED's BTW.... just don't like them, and I always remember what effects are on/off anyways. I tried looking around to find a site that shows you how to wire a up 2 effects in one box but I couldn't. So, I have a couple questions:

1) I need to use a DPDT toggle switch so I can turn the Fuzz Face on and off right? Which will I need though.... on/on, or on/off/on.... or something else that I didn't mention?

2) Do I just wire in both effect units directly to the input/output jacks, and DC jack, so I have both effects going to each jack? Or is there another method to do this? I'm assuming it's just like wiring 1 effect only there will be double the wires going to the jacks.

Is there anything else I should know about doing this? Do any of you have any ideas, or tips, or any comments?

Thanks for your time, and help.

Ah is that you LZ Nut? Check out the Dragonfly effects in the Layout gallery. I think that they have a diagram in there

^ You know it man.

I'll check that out.

Thanks for the help.

NO problem

tcobretti · December 21, 2006, 09:21:12 PM

I built something similar, and I used a DPDT in the traditional fashion for true bypass, then a 3PDT to switch between the effects which allows you to wire in an LED for each effect. The second switch is wired very similarly to the first, but instead of uneffected/effect you switch between effect 1/effect 2.

^kew...

I don't want to do that with this one though (gave me an idea for a future project).... I'd like to be able to use the fuzz combined with the octavia, or just the fuzz, or just the octavia.

Would I be able to do that with the method I mentioned?

Couldn't find the drangonfly layout or whatever.... I'll look it through again.

Fuzzy-Train · December 21, 2006, 09:43:21 PM

Yeah ok, found it.... was in the "mod zone".

It's done pretty much the way I thought it would be.... but it doesn't say anything about the power supply though.

Can I have 2 effects units going to one 9v DC jack? And, should I use an on/on toggle switch to activate the fuzz?

EDIT: nevermind I'll just use another stomp for the fuzz.

Two ways to do this come to mind.

One would be just be to house both effects in the same box and power them from the same power supply, but have each effect be essentially separate. You could have input and output jacks for each effect and use patch cords to decide the order. In this instance there's really not much reason to house them in the same box except for the fact that they share the same power source. You woulds have to press two switches to have them both work at the same time. In this example, the input goes to the 1st effect's bypass switch, then to the 2nd effect's bypass switch, then out.

The other would be basically the same, but you'd wire a master on/off DPDT so you could bypass both with one switch. This would bring the grand total to 3 DPDT foot switches. The problem here would be how to wire the input/output jacks. I think you'd have to decide what order the pedals are gonna go in and then hard wire them that way. So, in this instance, the input goes to the master bypass switch, then to the 1st effect's bypass switch, then to the 2nd effect's bypass switch, then out.

Something to think about here is the way the effects interact. In a previous thread we discussed that Hendrix's use of Guitar then Wah then Octavia then Fuzz Face may have allowed the Octavia to act as a buffer to kepp the wah from oscillating when running into the FF. So, you may want to wire the Octavia first, then the FF, and in this instance you may want to NOT wire the Octavia as true bypass so it buffers your signal and helps out your wah. Disclaimer: I have not personally tried out the Octavia-as-buffer idea and cannot verify that it works as advertised.

Fuzzy-Train · December 21, 2006, 10:47:02 PM

I'd like to do it like the 1st example... with 1 input, and 1 output.... I guess I'll have to figure out which one I prefer to go first.

The way I have it set-up now is guitar-octavia-fuzz-wah, it sounds pretty good, but I haven't tried any other ways setting it up due to lazyness. I think tomorrow (when it's not as late as it is right now) I'll try out some different ways see what I like better.

Thanks for the help.

Recently, I finally tried putting an buffer on my wah (which is hopefully similar to a non-true bypass octavia immediately after the wah), and it sounded great before the fuzz. I highly recommend you try it out before you cement your plans.

I'd either

A) put an output buffer on the wah and wire both fuzzes for true bypass
or
B) try the octavia as a buffer idea

I used a buffer by Phillip at Fuzzcentral, and it sounds great. There's a layout in my gallery. I've built two of 'em so far so the layout is certainly verified. Two tips: trimpot sizes vary, so make sure it fits before you cut the vero, and watch the pinout on the FET!

Another thing you may want to try at some point is building an Axis Fuzz. It is a love it or hate it pedal, but it is great with a buffered wah in front of it.

Agreed, put the wah first and use an output buffer.

Adjust to taste.

Fuzzy-Train · December 22, 2006, 03:36:33 PM

Fantastic guys... thanks a lot for the help and links.

I won't be finifshed this t'ill after the new year some time, (haven't even ordered the parts yet) but I'll post the end product in the pic thread.

Thanks a lot guys, and happy holidays.

Ah I forund something else on 2 effects in one box and all that... http://generalguitargadgets.com/pdf/two_in_one_wiring.pdf

RDV · December 25, 2006, 11:53:32 PM

You wouldn't believe how long it took me to do that diagram, it was like a brain teaser but it helped me learn to visualize things in my mind. It's cool that people use it.

Here's one without the leds from Dragonfly's layout gallery:

Appologies for bumping an old thread... but I didn't want to make a new one.

A little while ago I made this thread about making 2 pedals in one .... LOL... well, it actually turned into 3 pedals in one, and they work great (octavia, ge FF, and Si FF... i'll get some pics up somethime today or tomorrow)..... some of you told me about using the octavia as a buffer for my wah, but it doesn't really work very well as a buffer so I tried to make one using this layout:

http://aronnelson.com/gallery/Grooveyard/gywahoutputbuffer

Has anyone used this layout.... I'm having some trouble with it. It makes my wah sound very muffled, adds more bass, and drops the volume down. I tried adjusting the trim pot but with no success.... doesn't really seem to do much to the sound anyways, and the sound goes away completely when it's set all the up (or is it all the way down... not quite sure which is which with trim pots) I'm using a smallbear 100k cermet trimpot BTW

Thanks for the help in advance.

tcobretti · January 27, 2007, 07:08:24 PM

The layout looks right. I have built that one using my own layout and it works well. The only problem was it clicked if I swept the wah too quickly AND had the gain trimpot too high. So, I lowered the gain and all is well. The problem is most likely a solder bridge between two of the strips on your board. I do that all the time.

So, you tried a non-true bypass Octavia as a buffer after the wah and it didn't work?
