Keeley Electronics 30 ms double tracker. this is an incredibly versatile pedal, one of those special type of effects that is subtle, but very noticeable when it’s turned off. It doesn’t get in the way of your sound, it just enhances it. This pedal has a few modes, a dimension mode which produces chorus like tones similar to the Boss Dimension chorus. There is also an Abbey Roads mode which is a faithful recreation of the Abbey Roades studios famous Reverb room. Very useful on vocal tracks and instruments too. Lastly there is a double tracker mode which give you an amazing double tracked sound in a pedal form factor. it does it much better than Standard delay pedal due to the very specific range and voicing that the pedal was designed for.
