Positive Grid Spark Amplifier

Traditional gig amplifiers are large, heavy and donʻt sound that good at low volume. Over the years I have spent a lot of time and a lot of money looking for a good practice amp that can produce great sound at low volume. Voila!

The Positive Grid Spark amp fits the bill perfectly. It is small but powerful and sounds great at any volume. It has a basket full of amp models and effects and can also be used as a Bluetooth speaker. Everything can be controlled from the free app. And at 40w it can be used for jamming and some small gigs.
