pros & cons
SYMETRIX 606 DELAY £599
pros
• Excellent sound quality.
• Huge range of high-class delay, filter and early reflections effects.
• Comprehensive modulation and editing system.
• Separate knobs provide direct access to the most important effect parameters.
cons
• In-depth editing hampered by parameter numbering system.
• Display shows only patch numbers, not names.
summary
This is a wonderfully flexible, nice sounding effects unit that
offers something a little out of the ordinary. Used at a fairly
basic level, the front-panel knobs make effect editing very easy,
but in-depth editing is more complicated than it needs to be,
due to the lack of a multi-character display.
