We’ve been busy.
We’ve updated our Compatibility Article (previously Which Pedals Can Use a Vein Tap?) to include a greater range of pedals and manufacturers. We’ve also added details as to which prefer a Vein Tap, and which prefer a Vein Tap Plus (as a rule: Boss and Roland items like Vein Taps Plus, most others only need a Vein Tap but can use a Vein Tap Plus on the normally open setting).
Have a peruse, should you find yourself in the mood.
