Hi Drasp, love your stuff
Can you tell us more about the tap in/out jack?
Also, i came across this australian company Cubisteffects that does a feedback mod on the line6 stuff,
http://www.cubisteffects.com/2009/08/li ... fications/Would it be asking too much for you to look into offering that as well?

Many thanks & respect
edit: r3fx does the feedback/noise mod as a momentary switch

whereas Cubisteffects does it with two knobs, one for Feedback Intensity and one for Blend..

seems like this way you'd have more control and could pull off a more subtle feedback effect.. what do you think?
