I've had a TC Electronics G-major for about a year now, and have noticed that if i turn of the loop, the sound actually does differ from when the g-major is on. The sound becomes much more unnatural and "attacky".. Same thing when i have it on bypass.

I just wondered, has anyone experienced this? And if yes, does it just sound like that or is there something wrong with mine, since they're known to be totally transparent and uncoloring?

I'm using it through a Peavey 5150 and an ESP eclipse with EMG's if that would somehow matter.
