Top quality. You really need it if you want to control every possible aspect of Source Audio pedals. Don't be afraid to get into the midi and apps world (like I was). Plenty of opportunities there, still a lot for me to learn. And don't forget, a midi controller will be needed too if you want to change presets or control parameters by foot. Source Audio pedals really need a small fortune to be totally controlled but the quality of sound you get is unbeatable. Thanx Thomann for the excellent services
