Many decades ago, it is rumored that a certain, infamous “Spectre” created the effect we’ve all come to know as flange by putting a finger on a set of identical tape recorders, slightly altering the speed of one of the recorders. Through-zero flanging is an incredibly rare and inspiring effect, especially in the analog domain. By using two delay lines (as opposed to just one), Spectre can cross over the elusive “zero point.” This through-zero flanger pedal features an all-analog signal path that can be dialed in to create any amount of subtle and wacky flange tones. Spectre also boasts an impressive array of chorus and vibrato tones. Further, every knob and switch is connected to a little digital brain while your guitar signal stays 100% analog the entire time and never gets digitally processed. Since the control of the effect is digital, it opens up unprecedented effects and features that have never been heard or offered in analog stompboxes.
The Blue Knob Version (as opposed to the original Purple Knob Version) came about as a reult of customers loving Spectre except for the inherent background noise that it had. Armed with more noise mitigation know-how due to the Tonal Recall design process, this was addressed without affecting the “whale-like” regeneration. The other big change in the “Blue Knob Mod” is to the regeneration control. It was always crazy. Well, it still sort of is, just better. The whale sounds are now more consistent & reliable.
