Re: Are you using a buffer on your pedal board? Is so, which one?
I am adding a quality JHS splitter buffer on the front to get away from the EH buffer in the Mel9 which is not that great. I run dual rigs and right now splitting out of the Mel9 with its buffered outs is not ideal for me. I use a Radial PB1 buffer right before my Radial ABY which is after the Mel9 so I can mute it out completely. The PB also provides a slight class A clean boost on the Mel9 if needed, it is also close to an end of chain send buffer that also makes the ABY work properly. The rest are bypass until you get to my rack gear. Having gone through tons of pedals and various size boards through the years I am not a fan of not so great buffered circuit pedals like Boss and so on.
It's a matter of taste and what you like much less what you hear, or do not hear for that matter. A series of cascading buffers does a number on the guitars natural dynamics and pure tone, it just does.
About 20mins into this between Brian Wampler and another builder they discuss the issues of buffers and how not so good quality buffers can cause you to lose 1% of your tone quality per pedal. Too many buffers are a problem not easily solved without using bypass loopers to get them out of the chain. They agree having 5 cascading lesser grade buffer pedals which amounts to 2 per pedal can take 10% of your tone.

A chain of cascading buffers is sort of like picturing if you ran your signal through a chain of light compressors one after the other, the guitar will lose all sense of of its natural dynamics and sound.
As always if you cannot hear a problem then there isn't one.
It's all rather objective really, if you have a very bright sounding guitar that is pretty tinny then you might actually like some of the high end loss but along with that comes a muddier low end and that sort of percussive compressor like thing from too many buffers or a really bad one.
Just one good quality buffer renders any number of true bypass following it virtually invisible to any loading effect or cap loss. When you start having a bunch it can become a problem. Witness the spawn of the true bypass pedal age, it came about from pedals having crappy buffer bypass which was called "tone sucking", when high end quality buffers came along that issue went away. The thing about good buffers is also the increased headroom and bandwidth, I like Radial's PB1 and Elevator buffer/boosts as they have an adjustment to bring down the wide open 1M ohm sensitivity to where you like it but still providing you a class A driver buffer.
Ideal config is a good quality buffer upfront followed by bypass pedals and if you have fairly long cable runs back to your amp, a final stage buffer to drive the cables.
Someone once said a good test is plug your guitar straight into the amp, then into your pedal chain, note the differences in the sound clarity and headroom. A well config pedal chain will sound very much the same as if you were plugged right into the amp. If you do not hear any issues of high end loss or odd sounding low end including that compressive attack thing then you are probably OK. In all cases at various stages of our ever growing and changing gear development, you use what you have and you use what you like. Almost invariably at some point one gets tired of their same old pedal and gear chain and want some new or possibly better quality ones.
Speaking of the cat using an Archer as a buffer, I think those are reasonably pretty good and do the deal. One of the best sounding chains I had going last year had a Klon buffer front and end w bypass in the middle, was pretty cool. A Klon circuit does well before and after various drives and whatnot. We cannot always have the perfect config or choice of pedals and whether they are buffered or bypass especially if we like and want that particular pedal. So having maybe a buffer in the middle of the chain works fine. One should try not to get an entire chain of buffer circuit pedals going if you can help it or maybe loop them out with some bypass switchers.
