Good afternoon , I´m new to this comunity and first of all I´d like to thank you all for having me. I bought a czech 4/4 bass from a classmate at my current jazz school , and have been practcing with it ever since , it was quite pricey but i didnt though much of it being 4/4 Now i´ve found that almost everyone and plays 3/4. I am being offered an exchange for a 3/4 upright bass for my laptop , my question is , is actually harmful for my studies to practice on both basses? Is it a really considerable diference intonation-wise? I´m currently aplying to a classical school and I´m worried if practing on both double basses will mess up my technique or I just wont be able to be properly intonated on both. It just seems that in terms of transportation there´s no other choice, I love my 4/4 but it is almost imposible to transport, and getting this EUB would resolve a lot of issues for me. Any help ?
