i didnt realise you got high F build up when using multiple buffered effects.
I understand the concept of
loosing high end when using long cables + multiple effects with no buffers. same effect people aim for when running with a 20 foot cable up front to attenuate highs or something.
That's were I was getting confused. I thought you meant if you have NO buffered pedals you get increased highs.
I do have a true bypass loop switch I built, possibly to use, but mainly to test out how much a pedal can effect tone.
using that with guitar in & out to amp, and the switched loop containing (in order) ST-100 Tuner (true bypass), Wah (true bypass), chorus (true bypass), Delay (switchable True bypass off) even with only about 10feet in cable total, bypass that chain of 4 pedals returns clarity to the output of the amp. even with one pedal in that loop (a cheap buffered chorus) it can make a big difference.
I usually run with 4 pedals max, usually 3. tuner, wah, and delay. I don't like using many. So pedals boards isn't really something I care about that much.
EDIT:
http://www.petecornish.co.uk/case_against_true_bypass.htmlhere is that link. I thought the opposite of what you meant by "If you stack several true bypass pedals together, you have to have a buffer at the front or the back of the chain..." would be a stack of stack of true bypass pedals with no buffers at all... which is a situation addressed at the start of the first paragraph on that page.
