Can anyone tell from looking at my Vox V847 if its already been true bypass modded? I took it apart today to replace the old pot and bought a 3PDT switch to mod for true bypass but this doesn't look like any of the stock vox wahs I've seen online. It does seem to suck a bit of tone when it's bypassed but could also just be the extra cable dulling the tone a little.

Definitely isn't a 3PDT switch but is it still true bypassed or should I replace it? I can't seem to get onto the wah-wah.co.uk website at the minute to check it against their diagrams.
from what I remember when I bought it years ago the guy did say it was true bypassed but like I said it doesn't look like it has the right switch?
