Positive Grid · amplifier

The Positive Grid BIAS Head is a 600-watt amp-match modelling head for guitar or bass, built around the company's BIAS amp-matching technology, which analyses a target amplifier and reproduces its response rather than offering only fixed presets. The very high power rating reflects a Class D output section driving conventional cabinets, so it functions as a modelling preamp and power amp in one rather than as a practice device. That distinguishes it from the Spark range, which is app-based practice amplification. It suits players who want matched amp models driving real cabinets at stage volume.
