Bad Horsie Mod Question: Vol Pot & Voicing/Sweep (Ansil?

[nast2112]

Hello.  New to this great forum.  

This may be a simple question but I am going to do some mods to a Bad Horsie.  Among other things I am thinking of doing I want to add a volume pot that would give me up to a 15dB boost if I want when the pedal is active.  Here's the link to the schematic:

Where would be the best place to add the circuit?  Do I need to add anything? A resistor?  Which size pot should I start with?

I really like the functionality of the Bad Horsie but want to change the voicing and sweep to something more vintage (Vox-like?), too...

1. Is it possible to change/replace the inductor?  Is this what I should do first or...
2.  Possibly change R15 (that's in parallel with the inductor) to a 47 or 68K?  With Crybaby's this makes the wah tone more vocal.
3.  Possibly change C9 to .012 uF (or little higher?).  This is the 'sweep cap' and changing it should make the sweep a little more bassier and fuller (Bad Horsie are just a little too 'high end'/trebly for me).

Thanks in advance
Chris

1. for the gain boost i am asuuming you want clea. i would wire a pot in the last opamp fedback loop.  drop me an email and i will send you a revised schematic.   yes you can cahnge the inductor, i dont' recomend it.  if you want you rmorely to kick ass and scream.. se part of the problem is  the treble booster, that its configured as.

personaly i would take the whole thing there and put it in a regular wah pedal.  using a pot keep the one tl072 opamp as a buffer so you can put in your active boost.  
2.and put a 100k pot acrosss the resistor .  personally i wouldn't mod this pedal.. i did it once. and found it is easier to gut it and make it a perboard pedal in a vox style case.  and just conver the morley to a volume pedal or sell it. lol. thats what i did.

you got to much ear bleeding treble its not the c9 cap you need to worry about but the c10 change it to a .22uf.  or at least a .068uf. to open up some othe range back
