I just recently learned that the Boss TU-2 tuner can cause a significant loss in tonal quality, particularly on the highs, due it not being true bypass.
I use an Octa-Switch
as my pedal board, and I've always had the tuner before the chain even goes into the Octa-Switch.
So I moved the tuner into its own switch on the board so as to keep it isolated from the rest of the chain. However this board has an On-Off Buffer button, as can be seen in the link above.
Could somebody explain to me what exactly this will do in regards to my fx chain, pedals, etc? Can I simply have the tuner in any switch, and if I toggle the buffer to On it will eliminate that problem?
