For years, Malekko has been synonymous with the best quality BBD delays available. Today the evolution continues with the EKKO 616 MKII, a full featured yet compact delay with external modulation controls, an optional buffer, internal level pot and 650ms of pure analog bliss! Not content to leave well enough alone, we decided to go through every aspect of our acclaimed EKKO 616 to see how it could be improved upon. Every detail was scrutinized, data sheets compared, parts swapped, and hours of listening followed before we were satisfied. These resulting hand picked components of the highest quality are used to achieve what we consider the nicest sounding, most musical analog delay pedal we've made! The E616 MKII's specially voiced repeats allow a larger bandwidth to pass than most traditional analog delays. Turn the mix pot all the way up and the repeats will be near unity with the dry signal. The regeneration pot will take you from a simple slapback to a nice gentle decay of a few repeats then all the way to taking off into outer space with just a turn of the pot! Engage the modulation button and the EKKO 616 MKII takes on a whole new personality, from subtle chorusing or beautiful vibrato to way WAY beyond. Choose between true bypass or buffered bypass. The EKKO 616 MKII's revised buffer circuit is smooth and transparent, even with many pedals on your board. Tired of annoying volume drops? An internal trimpot (labeled "gain") will allow you to set the EKKO 616 MKII's level to your specific setup. The EKKO 616 MKII features these updates: - The modulation range has been massaged to allow much finer tuning for a more balanced overall effect - The MIX pot now allows louder effect levels - Improved buffering circuit resulting in flat response - Redesigned protection circuit for enhanced component saftey These changes add up to a cleaner, richer, sweeter, more flexible and musical analog delay. Even the EKKO 616 can appreciate that! AND at the same low price! Awesome! At Malekko, we are constantly looking at ways to improve our products. We enhanced our EKKO 616 using the highest quality components to provide you the ultimate expression of our vision. Enjoy. Well, I say, enjoy. Current draw is 40mA and operates on a 9V battery or optional 9VDC neg tip regulated power supply.
