Thermae represents a radically new approach to analog delay and harmonization. The pedal digitally manipulates the analog signal path created by four re-issued versions of the legendary MN3005 bucket-brigade delay chips. This creates the ability to change delay time in musically interesting intervals which allows for innumerable options for harmonizing and other sonic madness. These intervals can be sequenced through automatically or triggered manually for ultimate usability in a musical context.
Thermae can also be used as a more standard analog delay with unprecedented analog modulation options. Every knob and switch is connected to a little digital brain while your guitar signal stays 100% analog and never gets digitally processed.
- MIX (RAMP): Simply put, this is a magical knob. When you don’t have any dip switches assigned for ramping, this knob functions as mix control between the dry, unaffected signal and the delay’s repeats. Completely clockwise is 100% wet, full delay path, and in this scenario the signal will be boosted slightly. Completely counter-clockwise is 100% dry.
- LPF: This controls a slightly resonant low pass filter (LPF) on the repeats (wet signal). Set it all the way clockwise for brighter, noisy repeats. Turn it counterclockwise to filter out high frequencies and get a resonant boost or hump in frequencies immediately preceding that drop-off.
- REGEN: This controls the amount of repeats on the delay. If set carefully, it can regenerate seemingly forever, and can also regenerate into self-oscillating madness. The longer that a delay is regenerated, the sooner it will eventually devolve into a beautiful, smeary, tape-saturated blur.
- GLIDE: This controls the pitch transition time from one interval to another. Completely counterclockwise has nearly instantaneous pitch shifting. As the control is moved clockwise, more and more transition time is gradually introduced.
- INT 1 (SPEED): If Modulation dip is not engaged, this knob sets the first delay time interval change in sequence or in step mode. If Modulation dip is engaged, this knob sets the speed of the LFO (low frequency oscillator) for the pitch modulation on the repeats. Clockwise for fast modulation, counter-clockwise for slow modulation.
- INT 2 (DEPTH): If Modulation dip is not engaged, this knob sets the second delay time interval change in sequence or in step mode. If you are in step mode and only want to step between two intervals, turn this knob to “off.” If Modulation dip is engaged, this knob sets the intensity of the pitch modulation on the repeats.
- THOSE THREE NOTE TOGGLES: Ok, first things first. If you are using this as a normal delay (that is, you have both interval knobs set to “off” so there’s no pitch shifting) the left toggle is a simple tap tempo note division switch; quarter note, dotted eighth, and eighth. If you have INT 1 and/or INT 2 set to something, that’s when things get interesting.
- MODULATION TOGGLES: If the Modulation dip is engaged, you can use these two toggles for 9 types of modulation. The right toggle controls the shape of the wave for the pitch modulation on the repeats. Left for triangle, middle for sine, and right for square… nothing terribly unusual there. The middle toggle controls how smooth and/or random/glitchy the modulation is. Put in the left position for modulation that is completely representative of the right toggle (i.e. sine, triangle, and square).
- BYPASS STOMP: This Activates or bypasses the effect. This can be changed to a momentary bypass via a dip switch in the back of the pedal, if it is desired. This pedal allows for “True Bypass” via a relay, or buffered bypass with “trails” selectable via a dip switch in the back of the pedal.
- TAP / HOLD STOMP: Sets tap tempo, always honors the last two stomps. If you hold down this stomp switch, the pedal will go into self-oscillating regeneration “runaway” mode. This is the same effect as if the regeneration knob is set completely clockwise. If the step dip is engaged, the next interval in the sequence is triggered when this stomp is pressed.
- LOWER TOGGLE: This switch recalls presets. The right position recalls preset #1, the left position recalls preset #2. The middle position will always reflect wherever the knob positions, toggle positions, and dip switch positions are currently at. In order to save to the right preset slot, you hold down the right stomp (bypass) for 3 seconds, and then hold down both stomp switches simultaneously for another 3 seconds. The LED blinks and your setting is saved. For the left slot, you do the same thing, but hold the left stomp first. If you recall a preset, and move a knob, you will notice that the LED above the toggle goes dim.
