How to Modify the Ernie Ball VP Junior pedal to be an Expression pedal ( 10K Ohm Linear Pot for Roland/Boss/ Fractal

I too like the feel of the Ernie Ball Junior pedals. This is what I've used to mod several of them into Expression Pedals...

Honeywell/Clariostat 380C110K 10k ohm linear pot. High quality heavy duty construction.

http://www.onlinecomponents.com/honeywell-380c110k.html?p=44002872


Its a bit difficult to get a good quality ~10k ohm linear pot that will fit and will have the right rotation range etc. and will fit the string pulley used in the Ernie Ball Junior. And its clear from the Ernie Ball Junior pedals I've seen that the pulley does not fit the pot shafts properly on these pedals so even the manufacturer seems to be having problems sourcing potentiometers. But these Honeywell pots fit great.

Switchcraft 1/4" TRS Jack

This is typed from memory so here goes...

Disassemble the Ernie Ball Junior Pedal. Remove the three mono 1/4" jacks and circuit board from the back panel metalwork, discard jacks and circuit board. Save the existing wire between the pot and board to use between the new pot and TRS jack.

Unhook the kevlar drive string, remove the central black plate that the pot mounts on and remove the string pulley and pot.

Drill out the hole where the pot mounts to accommodate the larger shaft bushing on the Honeywell pot. You will also need to drill a new small hole for the anti-rotation/location tab on the pot body. Pay attention to where you drill this location hole so the pot body is rotated so the three solder tabs are pointing back most of the way to the rear of the pedal - so the solder tabs and wires won't foul on the pedal bottom or on the moving pedal top or the TRS jack. Install the pot on this plate and slide on the string pulley and mark the excess pot shaft length protruding past the pulley. Remove pulley, cut off the excess pot shaft with a fine hacksaw and clean up with a file. Reinstall the pulley. Some Loctite on the grub screw is a good idea. Trimming the pot shaft flush with the end of the pulley will make it easier to reinstall the drive string.

Install the 1/4" TRS jack in the rear panel left side hole as shown in the photos below (for most straightforward wiring) and solder wires from the pot to the three tabs on the TRS jack. The wiring is trivial, if in doubt follow the wiring in the photos below.

Reassemble the pedal following this guide on YouTube. If things are not going together don't panic -- just watch the video again, its easy to wind the string on the wrong way etc.

Attached are several quick photos of my modified Ernie Ball Junior....

When I get around to it I'll make a nice plastic label that covers the back panel and hides the two holes no longer used.

I tried a new pedal - mostly due to its size and low mass ( saves weight )

Proline Expression pedal   
http://www.musiciansfriend.com/accessories/proline-standard-expression-pedal




Its very similar to the M-Audio EXP - same length, but 1 inch narrower width = means you can fit more of these on the pedal board.

Here is the schematic
(Hint: if you remove the 1K Wiper resistor, its more compatible with Roland/Boss gear   






Compare to the wider M-Audio EX-P

Roland EV-5 Price hike

this is a bit ridiculous (and $100 more than the option above)

I have a Moog EXP pedal, and it does not work well with Boss EXP input,
it is designed for C.V. with a 100k ohm main pot and a 50k low limit trim pot.
It will be just a simple procedure of swapping the 100k pot for a 10k one though.
Here is a mod I did to my Moog Exp and it works perfectly.
Main pot 50kB and a 10kB trim

Wow is this a versatile  / small  / pedal solution - with much wider travel than you would expect from such a small size  - more usable / wider range of  travel than any Vox Wah-Wah pedal
and it works for Roland/Boss EV-5 replacement

For those of you looking for a physically small sized control/expression option:  I just purchased the

Hotone Soul Press Volume/Wah/Control pedal.
http://www.hotoneaudio.com/products/press/Volume_Expression_Wah_Wah_Pedal/75.html


 I can report that it seems to have a 10K pot in it and works very well connected to the Control Input of the VG-99. 
This pedal features a very compact size, metal construction, and feels generally very sturdy. 
It has 3 modes:  Volume, Wah, and Expression.  In Volume and Wah mode the unit requires power. In Expression mode you can connect a TRS cable to the input side of the pedal and the unit functions as a control pedal. 

Since it has a Wah function, it has a switch at the Toe position.  If you engage this switch while in the Expression mode, the expression signal goes to 0.  I've easily set up the VG-99 to turn on/off the Wah using that switch....

And, you can use it as a wah or standard volume pedal when not using it as a control pedal. 

Recommended.

Yeah, these in combination with the Audiofront MIDI Expression pedal to MIDI converters have been AWESOME.

I have an old EB volume pedal (from the 90s), not a JR, no tuner out. I used to use this as my expression pedal for my MIDI Mate. I tried "programming" my DD7 delay with it, but it doesn't seem to work (check light won't turn orange). I tried switching the send/return cable inputs to the EB. Am I just doing something wrong, or is it just not compatible?

Edit - I figured out that if I put the pedal all the way off, I got the DD7 to program, but it doesn't work properly. It basically turns the DD7 off if I push the EB 2/3 of the way down...must be the wrong pot in there or something (obviously, I know almost nothing about electronics)...

All Boss pedals with Expression pedal inputs rely on Roland EV-5 -and can not calibrate for third party pedals

The old EB Vol pedals use a 500K pot or 25 K Pot (marked 25K)

Neither work as a Boss EV-5 ( which uses  a 10K linear pot) and with specific 1/4" TRS cable wiring  configuration described on 1st post in this thread   
http://www.vguitarforums.com/smf/index.php?topic=33.0 

If you don't know how to solder  or mod a pedal - get a genuine Roland EV-5 , they have been $60 at Amazon for a while

As always, thanks Elantric.

I might be able to handle modding the EB, but I still use it with the MIDI Mate from time to time. Looks like I'm getting an EV-5.

Does anybody have a list of expression pedals which are 100% compatible with the VG-99?  I need more like the EV-5 but can't find cheap used ones and the new ones are around $100 now in Canada.
I've tried a few Korg expression pedals and they don't give the full 0-100 range of control.
I know it's something to do with the potentiometer resistance but don't know which other brands such as Moog, M-Audio, Yamaha may have same potentiometer as the EV-5.
-Thanks in advance for your info/experience.

There is a new Boss EXP out now, a smaller version of the EV-5
https://www.boss.info/us/products/ev-30/
Big Expression in a Small Footprint

For pro expression control in a compact package, there’s no better choice than the BOSS EV-30. Its small footprint is perfectly suited for cramped pedalboards, while the die-cast aluminum chassis offers a rock-solid foundation and BOSS’s famous rugged reliability.

A key feature of the EV-30 is an innovative internal mechanism that provides ultra-smooth feel and precise parameter control, delivering performance that rivals full-size pedals. And with two expression outputs, you can save further space by controlling two different devices from a single pedal. The outputs are electronically isolated, eliminating the possibility of noise issues from ground loops.

The EV-30 brings powerful real-time parameter control to the many BOSS compact pedals equipped with expression pedal inputs. It’s also ideal for use with BOSS multi-effects processors and effects switching systems. A handy polarity switch provides compatibility with a wide range of music gear, allowing you to use the EV-30 with most devices that support expression control.

There are many pedal options besides the Roland offerings.

In the UK,  Red Onion Switches are cool
http://www.redonionsolutions.co.uk/General/TripleMom.htm

Hi Guys,

Update to Elantrics posting about roland/boss compatible footswitches:

Red Onion are now called Bright Onion:

http://www.brightonion.co.uk/roland-boss/

I have a couple of these and the small imprint is great if you want a compact board/

e,g, for £20 uk I got a great, robust little pedal, basically a simple FS6 clone for switching patches up/down on my GT-001

Hi,

For information, i just receive a Lead Foot LFX-1 from thomann (24 euros or 19 euros from b-stock) which works perfectly as an EV-5 with GA-FC and Katana head 100.

im interested in that pedal , i wanna buy a Katana amp , and the only info i can find say that the compatible expression pedal is the Roland EV5 , however , it looks really cheap ...
that EV-30 looks fantastic , but im not sure it would be compatible with Katana

If you look for sales online you can pick up an EV-5 for a lot less these days.   With discounts I  bought one recently fro MF for $43.
