Abuelo de Bajo.

unfortunately, no blueprints have been made for any (original) instruments yet so I'll have to describe one.

"The Scrompophone"

The Scrompophone is a Single-Reed PVC instrument in the key of C designed without tone holes as for it is meant to be harmonic instrument (meaning it can only play the notes in the harmonic series of its fundamental note.) This instrument has about 256' of tubing and its lowest note is a Low C (C-4 or 1 hert,) and as for the highest note? Well that depends on how well the player is at harmonics as for there is no defined highest note.

While no original instruments have even a blueprint, some other instruments are based on an existing instrument. For example, a PVC OctoContraBass Saxophone, that can look something like this (except made out of PVC and like 1.5X the size.)

The Low Bb SubContraBass Saxophone
The Low B SubContraBass Saxophone
The Low A SubContraBass Saxophone

It is in Eb and its planned range (Minus extensions and altissimo) is Low A (Concert C0) to High F (Concert Ab2)
