Thanks all for your comments.
I really appreciate it.
Although, I love playing my Viola bass, I'm not overkeen on the whole neck dive issue, or the fact that it leans forward quite a bit if playing when standing up.
In some ways now, I'm not sure whether I should have opted for one of my other bass choices though, ie:
Epiphone EB3
Squier Vintage Modified Jazz
Just out of interest, does anyone own one of the two basses ? If so, would you recommend them, or do they suffer from the above issues ?
I must admit, given their relatively low cost, I could be tempted in buying one of them once I have developed and feel more confident.
Thanks again,
Fraser.
