This pedal has everything the M169 Carbon Copy is known for, but it's been tuned for a brighter sound with more defined repeats exhibiting distinct vocal quality. Engage the modulation button and your repeats will sing with shimmering beauty. 600ms of Delay time, an enhanced frequency range, Mix (dry/wet blend) and Regen (delay repeats). Two internal trim pots offer adjustable width and rate controls of the modulation for even more tonal options. True hardwire bypass. Powered by 9 volt battery or AC adaptor (ECB003).
