I have a Drum Perfect Groove Guide, which was the same kind of thing. It looks like they're not making them any more either. Their website is still around (drumperfect.com), but no mention of the Groove Guide. I use mine all the time, and now I hope I never break it
Yes, I worked with DFO members Chris/Blueshadow , Drummertom. Tommykat1 and Jordan Blue in beta testing the RokTempo. All were very helpful in providing feedback before I took it to market.
Now that LT Luglock is no longer selling the Tempo Ref's I have been getting requests to add the Metronome feature to the RokTempo. I am looking for a few beta testers to help me test out this feature. If anyone is interested send me a DM.
