Hey dude, what exactly do you mean by 'useable'? Are they just old or are they damaged? If they're just old i'll take a spiro medium A. Will you take £15 for it?
Cheers
The third one works well in G, the first and second suites work well on the bass at pitch (mostly up in thumb position). Some polish player has been uploading transcriptions in different keys for bass on youtube which sound nice but obvsly alot of the chords are abreviated
