I'm looking for some cheap copies of method books for bass trombone and tuba. I'm a freshman in college so money is very tight. I'm looking for copies of the Aharoni method book, Arbans book (either trombone or tuba, don't really care), and any other bass/ tuba books, someone may have. Condition really doesn't matter too much, within reason. My price range is very small, maybe $30 altogether, but that's all my budget would allow unfortunately. Email is the preferred method of contact because I'm not on the forum a whole lot anymore. Thanks!

Back when I was learning most of the method books we use today weren't written.

I was handed a trumpet method book and told to read it as bass clef (adding 3 flats to the key signature).  Trumpet music goes from 3 ledger lines down to 2 ledger lines up so that covers most of the bass trombone range.

You can get a trumpet version of Arban's for free on IMSLP.  That's probably within your price range.
