Re: Thinking about adding a wah
True.
A buffer up front is usually desirable. Some pedals the manner of their design work better with a buffer, like the Klon for example.
True bypass is desirable in most pedals as too many buffers is a problem much harder to deal with than none at all. True bypass loads down the signal but one good buffer in front of them lifts the loading from all. A good buffer near the front of chain is ideal followed by true bypass, one at the end of the chain if you have to run longer cables back to the amp line.
Problem is not all effects function well with low impedance signal a buffer does.
You're right about Hendrix he wanted his high end cap loss as his Strat's were high ended and tinny, not to mention noisy as hell. He used that long curly cable to further roll off his high end.
Another trick he used to was have the fuzz face on but roll down the guitar volume for his clean tones, one twist and he had his fuzz back. Quite possibly the first attempts at an overdrive or clean boost.
Equipment was very limited in his time and he did the best with what he had with the help of Roger Mayer, that was also an age of hardly any two things being consistent in quality and alike. Everyone treasures anything of that era, like Univibes even though no two of them really sounded the same.
True manufacturing quality control and consistency came later.
I give Jimi props for spawning the guitar pedal era and changing the sound of the guitar to where we are now. He was an inventive genius with the help of some great engineers.
One of those original cats that comes along once in a lifetime.
The chap that got me to pick up a guitar and spawned my love of effects and pedals was Robin Trower.
