How to modify a Vox V847 Wah Wah Pedal to change sweep range, add true bypass switching and a status LED. Apologies for sound quality guitar sounded a lot brighter than on the video. For further details check out the website at

Thanks
Sweep range mod is magical. I transformed it into a true bypass awhile ago, but now I added 10nf in there and it's sounds much, much better. Almost no noise and overall frequency response is what it should sound like as a base model i think. Although i personally don't see the point of going higher, unless you need a bass wah, with 10nf it's sitting on the edge of my clean signal already, but then again it's totally worth it.
Hi glad you like the video, you need a DPDT (double pole double throw) footswitch to do a basic true bypass mod. If you want the LED as well you need a 3PDT footswitch. You should be able to source from any decent electronics suppliers or stompbox parts suppliers.
Cheers
Finally a sweep range comparison! Thank you
If you look at the webpage in the description it has a link to another website that has an older version of the circuit board on it. This is where I got the ideas for these mods.
Hope that helps
Very helpful ideas, but I wish you'd shown us the step by step processes for inserting true bypass switch - it's much more helpful/reassuring when you can follow the steps 'you see'.
I've just scored an old USA made V847. I'm going to make it true bypass and eventually i hope to have all the functionality of the Dime Crybaby.
You could use a VariCap and include a control on the outside of the pedal, would give a wide range of the Wah range. Nice video. Merry Christmas.
your mod is called "sweep range", but it isnt really extending or contracting the range at all, or at least it doesnt sound like it, ive done the same mod. it is changing the center frequency of the sweep.
and before anyone whines about me being pedantic, the only reason i clocked on this video is because i thought there was an actual sweep range mod going on here.
Hook the ground wire up to one of the jack terminals with a black lead coming off it. There is a diagram of how you would wire a DPDT for true bypass on the website, I have added a link in the description above.
hope this helps
Hi, I haven't looked at a V845 myself but the wiring to/from the switch should be essentially the same although wire colours may be different. As such you should be able to follow the same method for installing a true bypass switch. One thing I didn't mention in the video the replacement switch may not be exactly the right height for the pedal to trigger it, I got round this by sticking some thin card under the pedal to get it to match up. Good luck
I've watched the whole video waiting to see how to install LED....... :(
also i know that when you have the pedal in front of you everything seams easy but big close ups would be good especially when quality of the video is really low (360p)
thanks for the video tho!!:) i like the capacitors mod , but didn't understand exactly how to solder them together
Could you just hook a pot to where you are putting resistors and have it adjustable from outside the pedal?
Instead of trying out a batch of capacitors to get the one required to give you a different tone out, be it one with more bass or treble, I think an even better idea would be to drill 2 holes in the case, put 2 test instrument sockets in the holes and solder leads from these, one to each leg of capacitor C2. That way you can make a kit of capacitors of different values that can be put across the new terminal sockets (maybe using croc clips connected to terminal plugs) as and when required to alter the tone of Wah Wah. It would also enable you to revert to your original Wah sound when need be. A future modification maybe?? I know I'll be doing this!!
hey, that sounds sick, especially for going from very treble filled wah like kirk hammet in many songs to very dark heavy wah like tone for more crunch
hello
how I can eliminate the ssh noise using the AC/DC adapter
in the wha 847?It increases with other effects as distortion and others in the chain.
It is possible put 1000 pF ceramic capacitor filter between the power positive input of adapter and the
mass (negative) of the pedal?
I provided that stabilized power supply and the rest is good.
I'll wait your valid suggestion with a schematic diagram.
Regards
hey , cool project , but why dount you use a pot instead of the treeway swich? i belive that will remowe the "popping sound" .
This one is identical scheme as mine. I bought last year, made in China. It’s very different from the one v847 that I bought in 1996 made in USA.
hi, great mod, Like the idea of true bypass switch and LED.
I have a a question about how you wired the LED and ground wires to the DC Jack. On the diagram on the website the dc jack - is the boss style one. Vox has a lil different one, which confuses me a bit.
Do you have a pic or could explain to me how soldered the wires to the DC jack.
Many thanks
good evening I'm looking for the pcb diagram for vox pedal wah wah thank you
What LED should I use? I found the switch on Amazon, figured I'd get the LED there as well, just not sure what spec to search for. Thanks and great video.
hey bro nice vid. i just brought a v847 and i want it true bypass. what the name of that new piece to put in? double fro somethin switches? where can i find one?
I have done this 3 option sweep mod as well as making my pedal true bypass and putting an LED in the pedal. Though I’m having difficulty with doing the volume, mid range, bass and gain, and vocal mod. I have the same board layout as your Wah pedal and the website you listed has a different board in the pedal. How do I do the mods on the website you listed, on the pedal you are using in your video?
would be very nice of me capasitores values and I wonder if the original parallel places in Honduras and really am not very well speak very good English but I wonder if the video is the same rocedure for the VOX V847 made in china ?
Thanks. I got a carlin dpdt footswitch for the mod. Which is the ground wire on your mod?
I have the new vox v845. want to convert it to true bypass. Is it similar as this 847 mod? Thanks
I JUST WANT TO KNOW IF I CAN SWITCH ON TRUE BYPASS USING MY DAPHON DF2210 WAH PEDAL AND PUT A LED ON IT?
Hi! I made it (actually, I don't know how, cause I don't understand eletronics)...
But the only problem Is that the VOLUME is way down... any tips? Thanks a lot
I've looked all over on UTUBE for how to make my newly just bought Vox V847-A easier to push pedal down on and off switch it's hard to on and off please help
Exercise your legs & feet.
Hi i have the Vox V845 Wah, would the switch mod work on that? my pedal is a massive tone sucker at the moment
Where you from man and would you do these mod for someone and how much all in?
im new to wahs where is the battery? i think i need a new one
It works with v847a?
This will work on VOX V845? Thanks
***** in VOX V845 all the same. For wah mod info see my channel!
Thanks Alexander
Boa noite realizei todo o procedimento no meu pedal wah, coloquei um led para sinalizar o on e off, quando ligo a chave 3pdt 9 vias da um estalo no momento do ato de ligar, quero saber como posso retirar isso ou se realmente tem algoma possível possibilidade?
Eae Lucas, você conseguiu implementar as modificações?
Sim, tive que fazer algumas mudanças, não eliminei totalmente o estalo mais ficou quase imperceptível, também quando tiro o plug input ele desliga a bateria para não gastar!
Cara eu tenho um VOX V845, eu adoro o som dele, mas um MOD não faria mal nenhum, to sem coragem de fazer a modificação e conheço pouco de eletrônica, tem como tu me dar uma forcinha cara? Vlw.
posso te enviar meu esquema eletrônico, mais é fácil fazer o mod só tem que entender pelomenos o básico e saber usar o multímetro!
e o meu tem uma diferença dos outro foi que criei uma placa de CI de verdade!
Lucas Rocha amigo, meu email é heraclitothiago@hotmail.com envia pra mim =D vou estudar um pouco de eletrônica
hi, test sound? please
or review HD jejeje :)
Hi TEST SOUND please :)
what the f... why dont they install this mod stock and just send the bill to buyers or just include the mods and customer pay for it??
Secreto debelado
you said 9.947 first then you said it was 9.957..which one is it..LOL:) This video is so low res I can't see a damn thing as far as detail. It's one big blur. Redo the video at a higher resolution so we can see what's going on with the soldering and connecting.
