    Question 1 year ago

    Hi momon_crot, I found your instructables very clear (I have a zoom g3x and I am willing to do this mod too), especially step 7 where you show ho to connect the switches to the plug. From ashbass website there are also other mods (tap/rhythm - bank - scroll); as far as you know, do you think that working as you show in this instructable will work also for other mods? Thanks for your attention
