That's always been my biggest gripe about the magicstomps is lack of tap tempo, or some kind of tempoe sync. What an amazing pedal other than that! You've got a really nice board- I'm just surprised you don't find a tempo delay a must have.
Not on this board, It's more for presise rehearsed work.
The AC runs to another acoustic magicstomp BTW, I can run both the electric signal and acoustic sim simultaneously into one amp by sending the AC signal to my FX return. Monster sound, just like the van halen "can't stop lovin' you' intro.
There's a great little nobels signal splitter under the noise suppressor to send the signal 3 ways - tuner, electric and AC.
The second magicstomp has a number of presets that are clones of my amp for emergencies such as tubes blowing.
The board switches to battery backup automaticaly if the power supply cuts out for any reason, no need to disconect the power leads.
The A/B box serves for when I run my acoustic through the board (also for the aforementioned amp blowing scenario) - I simply flip it into the PA, the first magicstomp features lots of acoustic/mandolin/banjo/violin presets too so this really helps with multi instrumental gigs.
