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.
i use fender hot road deville(tube) and i use a neutrik cables(short-cables).
with this set up i hear a different kind of sound switching between relay and dsd (truebypass), but with the relay, the switch is not silent (when the pedal switch from off to on (active), not when the pedal is activated and i switch only the persets or banks.
