That's not what transparent means, most equipment is actually like that unless used in exactly the wrong way.
I'll restate the second part of the last post: [breath] the fact that something was said in, on, or through Youtube, HCAF, UG, TV, the radio, a magazine, a guitar shop discussion, or basically any other place where large numbers of musicians with very little knowledge of anything say lots of things they themselves don't understand that well that was not mentioned above [/breath] is not grounds for it being true or accurate.
What's more, none of the TS pedals fail to be 'transparent' in that sense unless something is seriously wrong with your rig. The differences between the various pedals are practically insignificant and the differences you hear are consequences of your own misinformed expectations. If you actually do a truly blind test with several pedals of each make and model you will not be able to pick the pedals apart at a rate any better than random chance, period, end of discussion.
