Right on both accounts^^... that was it! now it's working and quite nicely i might add.

i had misinterpreted the rewire and cut the trace at pin 8 instead of at the cap thus cutting it off from the rest of the circuit it's dependent upon hence the suspicious drop in voltage when switched to LP because the two 22K weren't able to feed the leg of that circuit. little bit of a green move

i know but i could've gone the duration not realizing it had i know brought it up so thanks again.
also, just to confirm what others have said... "low pass" mode indeed has a nice lil boost in the signal witch is a nice bonus for the effort.
now i'm curious about the "bleed" 220k resistor or pot at cap11 (i believe).. Q: what sort of effect does this have exactly.. does it sustain the envelope longer or the opposite. because i'm looking for a way to elongate sustain a micro second or so as i believe this would help balance the attack between the high strings vs low strings (non-wound vs wound resp. )
i find the wound strings little too silent when i've dialed in how i like the higher strings to sound. btw, i always start at a Garcia (estimated prophet) and/or Zappa (Inca roads solo) classic envelope filter sound first and foremost as it's my favorite for envelope filter sounds, fro there i do occasionally venter past that to other types of sounds.
That said i have it purdy darned close especially with the LP mod. now a few fine tunes here and there and i believe this pedal can cop a Mutron 3 or a Maxon AF-9 with relative ease... what do you think...??
