Best pickup for non-adjustable bridge?
Hello! I played professionally, my friend is a professional violinist and budding bluegrass bassist. Her boyfriend wants to buy her a pickup for her birthday- but, unfortunately, her bridge doesn't have risers so I can't recommend the Full Circle or the New Realist. I use the Full Circle as well as the Revolution Solo II; I love them both but I can't recommend the Revolution Solo II because it is incredibly particular, especially fitting it in the wing, and I feel like I got lucky.
She wants a darker sound so I would recommend the copper Realist but surely there is something better, I find the copper Realist to be so lacking in highs and mids that you can't get clarity and articulation no matter how many EQ pedals you stack together. Is there anything else that anybody would recommend for a darker, thumpy double bass pickup that works for pizz and arco that does not require an adjustable bridge?
EDIT: budget is $300, $400 max
