We usually talk about true bypass or not. Here I would like to share an article by Seumour Duncan that clarifies this topic:

I have 8 Truebb Pedals on my board. And they are all high quality pedals. However if you put too many TrueBB pedals in your chain, they do change the sound. I loose upper mids and highs. That's why this thingy is now the first unit in my chain

PureToneBuffer . This helps sooo much !!!!

If you are gonna use pedals, the PRO TONE BUFFER is crucial IMHO smile.gif It will give you your tone back!! It's getting sucked out each time it goes through a "True Bypass" pedal.

Also, part of the reason so many folks moved to multi efx boxes / processors smile.gif But IT's a big world with plenty of room for old style pedal boards, 59 Strats, and any vintange/traditional gear that one might want smile.gif

On my bigger boards I have a quality buffered pedal first in line, usually a tuner or a Demeter compressor, and also one at the end of the chain - a boost or a delay.

My take on this is that a (genuinely) true bypass pedal is as transparent as anything can be.
However, with a multi-pedal arrangement, all those short interconnects between them add capacitance which loads the pick-up and brings down the resonant peak.
And if some of those interconnects are low quality (or even poorly terminated / otherwise faulty) then that effect increases, perhaps significantly.
This page http://buildyourguitar.com/resources/lemme/ is one of the most helpful I've found for clarifying the issues and constraints surrounding pick-ups and how they impact on tone.
From that, it may be seen that it's unrealistic to go from the guitar, through a 20' / 6metre cable, then maybe 6 true bypass pedals, then another 20' cable to the amp (maybe about 2000pF in total), and expect the bypassed tone to be the same as plugging straight into the amp.
So I agree with the above conclusions, that a buffered / buffered pedal, near the beginning of the chain, is a good way to avoid loading the pick-ups and so maintain the expected tonal character.
Pete

Interesting article. That picture of the guitar pedals is insane, imagine the tap dance you'd have to do to turn your delay off..
