Alexander Quadrant vs Boss DD-500. I recognize the Boss is more powerful in terms of # of presets and types of delay but interested in pure quality of delay tones. Can anyone share their experiences as well as any pros/cons with these 2 units. I’ve had the opportunity to play and own many of the great multi delays (ie. Empress, Strymon, Source Audio, Chase Bliss, etc) and had recently simplified my live setup using only a Boss DM-2W. That said, I deeply miss having tap tempo and access to a few presets hence my interest in these 2 delay pedals.
