I've owned a Positive Grid Spark 40 amplifier for about 4 months and it's a great little practice amp with loads of features. Every time I release a video about this amp I always get comments about how terrible Positive Grid customer service is. In this video, we look at the BAD and GOOD points of this amp. The Studio Rats are core band members Paul Drew on guitar/production/mixing, drummer James Ivey and Dan Hawkins on bass. They collaborate with singers and musicians to produce radio-ready songs.
