I am just learning to use shapshots and I keep running into a problem. On my clean preset I have a snapshot 1 of clean/reverb, snapshot 2 is chorus/delay, 3 is drive, 4 is drive/delay and all work well. However my 5th snapshot is just clean with a compressor and when I select it the tone is all trebly. Any adjustment on compressor does not change this so where is this treble boost coming from? Also I can't get the wah to work yet it works on the other snapshots. Any advice would be appreciated thanks!
