The Tone City Tape Machine Delay is s Hybrid, mini delay pedal. While the dry signal is analog, the delay part is managed by a digital circuit. This allows Tone City to keep your base tone authentic yet offer the vast delay options that only digital circuits can offer. The Tape Machine Delay has a simple 3 knob layout, it offers up to 600ms delay time and all in all a quite versatile pedal. A Stereo output would have been a great addition but hey, for such a killer price we have no complaints.
