Positive Grid US

Arrived when promised but customer service slow to fix problems with software (does not control guitar patches changes)

See my review!!

It’s a cool little toy for guitar players, but that high pitch tone thing really ruined the experience for me. Was my first time playing with it, never seen anything like that before.

Eh

Spark 40, a stroke of genius. Not including a 1/8 to 1/4 " summing cable, idiocy. By releasing the "Spark Cab" you're basically shooting yourself in the foot, as there are so much better FRFR powered speakers (like the Fender FR12 for example). The hiss from the Spark Cab is horrible. But with a 1/8 to 1/4" summing cable with resistors (20 bucks on Amazon) you can run your spark (mini, 40, etc.) into the effects loop of any amplifier (replacing it's preamp with the spark), or powered FRFR cabinet that doesn't have a horrible hiss, and get amazing results. I'm a positive grid fan, but releasing such a subpar product as the Spark Cab was nuts, and not including info that would let anyone use ANY spark with any amp that has an effects loop (with a lousy 20$ summing cable) is a huge HUGE slap in the face.
