I wish Octave pedals would track.
I wish the TC Electronic Flashback, which has the potential to seriously be the most frikkin' bad@$$ delay EVER (especially at that size) would do two of the following things, which I have emailed to TC and would ONLY require a firmware update:
1 - Wish the LED would blink in a 1-2-3-4 division (it does this in the Looper mode so I know it's possible) so you could keep an eye on the really long delay times, AND
2 - Wish the 'quiet and strum' tap tempo replacement trick, which is quite honestly genius, would actually track longer delays. It's a 6-second delay, but the 'strum quarter notes' thing only works for quite short delays, unless I've been doing it wrong.
Fix these two issues and that box is GOLD. Seriously, stereo delay with infinite feedback, something like 9 modes (some of which I'll admit are redundant), and an internal dip switch for spillover even in mono-out? Brilliant. Wish others would take a hint from these guys.
