heh, if thats what you want, having more digital pedals in the loop can do some big noise, can try the wah pedal at the last pedal of the loop before the out from the wah go to the loop return. The wah will scream and wail loudly at certain setting.
watch out for the noise/sudden beeps/high pitch squeal thou, sometime it will get outta control(especially with the modulation pedals into oscillating delay within the loop of the feedback loop), amp speaker might not be able to take it...
