Hey all, recently been trying to flesh out my library with books on building amps and guitar effects/audio electronics

If anyone has any books they don't want I'd be happy to make an offer for them.

A couple in particular I'm after are Merlin Blencowe's books on preamps and power supplies, Richard Kuehnel's books and Morgan Jones' books

But I'm open to any useful reference and text books the may be relevant
Epiphone Les Paul Plus Top
Jet City JCA5212RC (SLO Modded)
Ibanez WD7 Wah
Mad Professor Sweet Honey Overdrive
TC Electronic Flashback Triple Delay
TC Electronic Trinity Reverb
