Dallas RM sucking tone when bypassed...

[squidsquad]

Set-up = Strat into RangeMaster (PNP positive ground) into Mosfet Boost into minbooster.
Sounds great...until I bypass the RM....and I get bad tone sucking. 
I'm guessing because of the positive ground connecting the next box,
leaving half the circuit connected? 
I dunno.  Any simple way to fix this? 
Would a negative ground NPN have this problem?
I'm using a standard DPDT switch.

Is it wired for true bypass?

From geofex:



You may know know about true bypass, but just in case I figured I'd be proactive.

[squidsquad]

Yes...thank you...as in the top left illustration...it vexes me.

  I'd check across the switchings with teh DMM to see if the continuity across the lugs is good, you should be able to get a beep from input tip to output tip when in BP mode.

Makes sense.
I'd also check for crud build up on the jacks.

Should be pretty easy to solve with the DMM set to the lowest ohms range... IE showing resistance in the leads themselves. From there just step by step follow the bypassed signal.

I'm assuming this acts the same way no matter what's following it.

What do you mean by "leaving half the circuit connected".

Well....I was thinkin (wrongly) that with neg ground on one box...positive on another...no jacks isolated...
perhaps backassward current was connecting the circuits somehow via ground....however...
It sounds like a simple wiring error. 
I have a 3 way input cap switch...and it is faintly doin it's thing in bypass mode.
It's wired after the stomp-switch...but must be sneakin in somehow.
However....the volume & tone control are (correctly) disabled in bypass.
(It's a java boost attempt)
So...I know WHAT is sucking...now if I can find where/why...hehe.
