I use a buffer before my pedals , differents overdrive (ocd,ac booster) and at the end the time factor.
I hear an alteration of my tone (brightness-less warm) most with this overdrive.
if i set the Truebypass on Relay and i switch off the Tf the sound is good, but when i switch on the pedal i hear a clip and then the sound is altered (BRIGHTNESS)…i hear the clip only during the switch on-off a preset ,not switching between two different presets
if i set the pedal on Dsp the sound between active or not is the same but it's altered(-brightness most if the overdrive is on- -the drive sound is less warm). in this case i don't ear clip switching on-off the pedal.
