In addition to an easy-to-use “3-band equalizer,” this amp features a “Shape” function for even greater flexibility in creating sounds and rich sound variation. The amp is equipped with a total of three bass effect systems, including “COMPRESSION,” an “EFX” system with CHORUS, FLANGER, and T-WAH, and basic “DELAY/REVERB”.

FFP (Feed Forward Processing) is system control technology that optimizes the performance of the amp, speakers, and cabinet characteristics according to the signals being input, based on the results of analyses of the operation and behavior of each section of existing amp systems.
COSM (Composite Object Sound Modeling) is Roland’s innovative and powerful sound modeling technology. COSM analyzes the many factors that make up the original sound, such as the electrical and physical characteristics of the original, and then produces a digital model that can reproduce the same sound.
