Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement.

The Alexander Pedals History Lesson Vol. 2 is a three-mode stereo delay covering the classic delay spectrum through era-specific voicings: 1963 mode delivers warm magnetic tape echo with progressive treble and bass rolloff per repeat, 1977 mode delivers analog bucket-brigade character with murky slightly colored repeats, and 1984 mode delivers bright 24-bit clean digital clarity suited to lead lines and modern tones. Features tap tempo with three subdivisions, a Tone control for echo tails, stereo outputs with an analog dry path on the second output, and a modulation knob adding chorus or vibrato to any mode. No MIDI or presets.
The Mad Professor Deep Blue Delay is a boutique delay designed to capture the warm, natural sound of classic 1960s tape echo units while using a hybrid digital delay line with a fully analog, unfiltered dry path. Its bandwidth roughly matches vintage tape echoes, and the repeats are carefully tuned around the first critical reflection and how each echo decays, giving an organic, vintage-oriented character that blends beautifully with an amp. Crucially, it is engineered to work well with distorted tones, an application where many delays fail, keeping the dry signal uncolored and clear. Compact with a simple control set, it suits players wanting musical, tape-flavored repeats for slapback, rhythmic delay, and ambient trails without tone loss, equally at home with clean and overdriven rigs.
