Analog Pitch Shifter: Do I really need the Chase Bliss Audio Thermae or is there any other option?

Ask the DudeRecently, Chase Bliss Audio debuted the Thermae, an analog pitch shifting pedal.
This pedal is based on a delay. To every cunning guitarist, this fact poses the question, if it might be possible to create this kind of sounds with a normal delay pedal, too.

I would say: yes, it is possible to create pitch shifting effects with an analog delay like the Chase Bliss Audio Tonal Recall RKM.
Therefore, it is necessary to vary the delay time while you are playing your guitar.
If you reduce the delay time, the tone will be transposed downwards, while an increased delay time transposes the tone upwards.

A solution with limits: the expression pedal

It is possible to vary the delay time by hand or by using an expression pedal (provided that the pedal has an expression pedal input).
But the tone pitches would be quite dissimilar because it is impossible to adjust a pot or a pedal as exactly as it would be necessary.
But even by using an expression pedal, you can achieve interesting results.

The professional solution: Sequencer

Instead of an expression pedal you could also use a sequencer.
It can be connected quite easily via the expression pedal input.
Electro Harmonix (8 Step Program) as well as Korg (SQ-1) offer well-priced models.
A bit more expensive, but also more extensive is the Doepfer Dark Time.

Besides hardware devices there are also numerous software solutions.

A sequencer allows to adjust the pitches and their speed exactly and the number of the different pitches can be elected, too.

Most sequencer pedals also provide a random function to defamiliarize the delay sounds unpredictably.
The glide function allows to choose between chopped sounding pitches in separate steps and a soft transition between the pitches.
Now you can create interesting rhythmical pattern which may be pretty inspiring.
