I know what are buffers good for and that there are good ones (Cornish etc.) and bad ones (Boss, DOD...) and how they can affect the sound... My question doesn't refer to buffered pedals but to stand-alone buffers without any other effect or even switch- I've seen a few of those units (I think one of them was from LA Sound Design) Does anyone have any experience with using stand-alone buffers or do you know companies that make them? I know what is considered the best drive/phaser etc. but who makes the best buffer? Or doesn't the quality differ enough to tell?
