Works totally fine (tested in V:25, ROV25, Express 5:50+) and it sounds amazing. IMO, it's a smidge ahead of the FB X4 in terms of tone, but the "Vintage Digital" really sells it, and the flexibility is FAR beyond the TC.
Thanks! Really getting tired of the Flashback flakiness. Tap tempo is unreliable due to the switches, but I like having a coule 2-3 delays a tap away. I'll get one on order.
