I love this company, if I had my time over again I would just buy everything they do and make a case comprising entirely Feedback modules and revel in the glory of that sound!
Spotted this in the Marketplace and I can't believe it is going for this price:

Wicked delay! Bags of character!! An absolute bargain for a discerning wiggler!
I would snap that up if I hadn't built my own...
p.s. I have no affiliation with the seller or Feedback!
