Which is precisely why I'm asking actually 🙃 . Have a sitting gig and need to avoid sharp wrist angle... but also can't be holding arm out without resting somewhere or it'll put a static load on shoulder etc.
Options to try:
1. Explorer style to rest arm higher (pics of Entwistle suggests could work)
2. 335 style semi with large body for same reason (have tried this, it deffo helps)
3. Steinberger. Which might work, or elbow might drop even lower and be worse!
4. Try and play with wtvr on left leg, classical guitary, but gig gonna be stressful and don't want new techniques to occupy headspace too. Also not as fun as buying new bass.
So that's 3 potential forum threads haha. I'm starting with #3.
