Just had a look at the patches...A is a marshall model...B is my `noodling at home sound` which is SLO 100 crunch with comp , dist, rev, and delay. C is the factory patch `Ambient Delays`...when i play live i have amp models off and use a Fulltone OCD in the loop. this then goes into the clean channel of a marshall JVM410HJS for my function band. For my Rock stuff i use the JVM sounds with the firehawk 4cm. Comp/Wah/Od up front and Rev Delay in the Loop. In this situation there is Zero lag as i`m only turning fx on/off with the Firehawk. The other way there is the same amount of lag you see in my video which is acceptable to me. I hope they get it faster for you in a future firmware upgrade as i really like the unit :-)
