My mate is in the market for a solid delay pedal (no qualms about digital or true bypass). He's in the process of replacing a Boss GT-8 for some more organic sounds. Is there anything worthwhile in the $100 or less price bracket? I think he's presently eyeing off a secondhand Boss DD-5. He's already discarded a Line 6 Echopark as it had too many knobs. He's a singer guitarist so can't afford to be tweaking too many things.
