Vox Wah 847 Porn

[STRATDELUXER97]

Curly and I have been spending alot of time lately figuring out what makes a wah great...
I picked up this recent Vox 847 off E Bay and bought a spare board to tweak..Curly let me borrow his Teese RMC1 last week...This wah is my attempt at getting the same vibe as Curly's wah...I say "vibe" as I don't have Teese's inductor and pot in the equation...This wah is all about the strat player....Full sounding,smooth,no shrillness in the highs and a built in "boost" circuit that gives the wah it's balls...

Check out a Teese RMC1 Board here...Scroll down to the big board photo and compare mine to his board..Mine isn't an exact copy,but it's voiced with that vibe in mind..

The wah is complete now with my power supply board so I can run a 9v adapter,true bypass via a Fulltone 3DPDT switch..Fulltone pot,fulltone inductor,big upgraded caps,metal film resistors,tweaks to the board to get the wah to meet my fussy requirements...This is just to give you an idea of what can be done with the Vox 847s....This is a very vocal wah and I like the way it turned out..Thought I'd share it with you all..

Re: Vox Wah 847 Porn

Here's another board I did last night that has a yellow fasel inductor and an on board adjustment pot for "gain"....This board is voiced like an original Vox Clyde McCoy...Clean,brighter,and very vocal sounding...These boards just drop right into your 847 after you remove 2 screws and the connector..I'm just starting this and I don't currently have any extra boards to sell...They'd have to be ordered and built 1 by 1 by me...Cool solution to give your Vox wah some different wah tones? :dance:

I'm currently using Curly as my guinea pig as he listens to some of my board ideas.. Lew also has a VOX 847 I just completed for him...

R1 is left empty on the board so a guy can mount an external 100k volume pot...This volume pot gives you perfect unity gain between your on and off wah volumes..At real high volume settings you get slight compression and alot of output from your wah.If a guy doesn't want to drill a hole into his wah for the volume control,we put the resistor back in R1...The transistors are either BC109Bs or higher gain BC109Cs like this board has on it..I haven't figured out how much to charge to sell the boards,simply because the inductor alone is around $20 to $25? The boards are $16 and this is before I do any board work?

My plans are to offer a very vintage sounding board based on the early Vox Clyde McCoy wahs of the late 60's and also a warmer,smoother,ballsier board with a slight gain boost...This board is similar to Teese's RMC1 board in that it is less bright,still vocal,but darker in it's presentation...Right now,the boards and inductors would have to be ordered..If you are interested in upgrading your Vox 847 wahs...Contact me..These boards are specific to the Vox 847 unless I hard wire to your Crybaby wah etc...If you'd like the mods done within your current Vox 847 and using your board..We'd just need to order the inductor of your choice..Fasel red,fasel yellow,Fulltone etc..The Fulltone pot and a DPDT switch if you want true bypass..The power supply is time consuming and will be extra,as I Make the boards from scratch...

Re: Vox Wah 847 Porn

thats ALL there is to this??? or is there more circuitry?


lets see.. pots for volume change, capacitors for the RC circiut for changing the sound pitch hum hum... thats REALLY all there is to it >.<

Well...You have to know how to voice the circuit and what components and component values to change..If you tweak the board you still benefit greatly by getting a great inductor and full sweep pot into your wah...It's the total combination of all parts that gets you the sweep and vocal expressiveness from your wah...External pots etc..are things that can be done if I do the work on your pedal..The board literally is removed just by taking out the 2 screws and unplugging it..You then substitute with another board...

If you don't need a power supply,you just do the board tweaks,replace the pot and install a DPDT switch for true bypass and you now have a great wah...Lots of range and alot more vocal..

Re: Vox Wah 847 Porn

John: You're wah mods are really appealing to me! I PMed you before about them a ways back. Basically I eventually want to have three wah sounds: Tom Morello's in "Bulls on Parade" (My Dunlop Hendrix wah gets close), Claptons in Cream's "White Room", and a more modern wah like in "Summer Song" by Joe Satriani.

Do your mods nail that "White Room" wah sound? Also, can you mod a wah to sound more modern, or could you recommend a modern sounding wah to me instead? Thanks man.

Hello Joe...The Clapton Cream wah tones were all about the earliest Vox Clyde McCoy wahs...One wah board is voiced on that line...The other board is voiced with a strat/tele in mind in that some of the really highend toe down tone is eliminated..The pedal is also bassier,warmer,and smoother and has a boost circuit to give single coils more balls..You have a smoother,stronger sounding wah,but with good overall vocal quality..

Not sure if this fits into your questions about Satch's tones etc.? Mike Fuller told me that Satch uses one of the newer Dunlop Crybaby wahs? He probably also uses the Fulltone Clyde,but Satch is an endorser for Dunlop....

Re: Vox Wah 847 Porn

John, is there a way you could say put a switch on the side of a wah to change its "orientation" from strat/tele to Clapton? You mentioned mellowing the toe-down tones for strat, would it be possible for a guy like me to send a pedal to you and get both in one wah, with the flick of a switch? If so, that would be absolutely Amazing

EDIT: and thanks a lot for the Satch gear info!

Re: Vox Wah 847 Porn

I have a Cry Baby THomas Organ Company Wah from the 60's that John Modded for me about a month ago. Prior to this mod I was using a Vox Clyde McCoy. The Modded Crybaby that John did for me just flat out smoked my Clyde McCoy. My Amps are Marshall 900 & a Fender Super Reverb. I use three guitars primarily a EC Strat, a 335, and a Tele. In all cases the Modded Crybaby just out performs the Clyde McCoy. I also have a Vox 847 that I will send to him sometime in the future to have him work his magic on. From what he has told me it will sound better than the Crybaby he did for me. I find that hard to believe, but this guy is a tone Guru.................... So John if you are reading this... probably after the holidays I will be in touch!! As far as the Clapton tone, a lot of that will really come from the Amp and Pups more so than the Wah. The voice of his modded Wah is real close to it though!!

I'm currently messing with the a switch that would cancel the boosted part of the strat voiced wah...This would allow the boost,more lows,and overall ballsier tone for the strat/tele guys and at the flick of a switch,the circuit would be removed and you'd be back to a stock style wah tone...I have the circuit completed...I need to listen to the results after I grab something to eat...That switch is currently mounted on my circuit board,but it could be mounted outside the wah also...

Also we can mount an outside volume pot that would give your pedal more volume,gain,and slight compression at high settings...Currently the Fulltone Clyde Deluxe and some of the Dunlop wahs have this kind of feature....Wish it wasn't so time consuming for me to post some clips of this stuff... :smack:

Thanks Bludave....So are you saying the modded Crybaby smoked an original and early Clyde McCoy wah? Wow! Is there something wrong with your Clyde McCoy maybe? :13: The 847 has more range and is easier for me to work on...It's also my favorite pedal overall....I bought my reissue 847 when they first came out in 93 and it's been a big part of my tone since then...I had a Dunlop Crybaby before that and it was a terrible wah.. :32: Glad you like your Crybaby..Very cool..

Joe....Yep....I Now have the switch all wired up...The switch removes the boost circuit in the wah and decreases the lows and stronger tones that the strat needs...With the boost circuit out,we're back to a stock wah tone that is thinner and brighter(Better suited to humbuckers and darker guitars)...There's some unity gain differences when you disengage the boost circuit,so the fix for that,is to install the external volume control...The un-boosted wah tones are thinner than my stock CLYDE type voiced boards but you do end up with more versatility with your wah and I'm still working on a way to get more bass and output into the un-boosted position,but it's pretty great as is right now if I left it that way...

Guys that use the bridge position on their strats and Teles would flip out over the sound of this board in the "boosted" position... :dance:

Re: Vox Wah 847 Porn

John,
The Crybaby you modded for me is my main Wah now. I had a 847 but the pot crapped out on it. I replaced it but it never sounded right, so I bought a Vox Clyde McCoy(I gues it must be a RI). That was my Wah until you did the Mod for me. Maybe what I will do is send you the Clyde as well as the 847 and let you work on both. Either way you can never have to many Wah pedals.

Send me both wahs....I have my own 848 that I like alot now after the mods..Curly has an 848 Clyde Reissue that I did for him also..Maybe Curly will chime in on the results of his 848 for you...The key is to have the right inductor..The red fasel is ok,but the Fulltone inductor makes the pedal smoother,seems to add lows to the circuit,and I get the most vocalness with this inductor...Add the Fulltone pot and some cool board tweaks using great caps and tweaked metal film resistors and you have a quiet and great sounding wah...The Clyde Reissue is ok stock and it has a great pcb,but it still needs some work...

I'm up to 4 wahs now....2 847s,an 848,and a Crybaby that Teese modded to an RMC1 that has his pot,inductor,and his board tweaks...I'd also like to have a Fulltone Standard Clyde wah and that'll be my next wah...
