Bit of a preamble. Questions are halfway down. After running through a bunch of exotic basses and cash, I am back to where I started which is with my three Turner Ren basses. One fretted, two fretless. Acousticores on one, Black Nylon on the others. Semi-acoustic piezo basses are my thing. So with my 2 fretless basses, I want the lowest action and the most mwaah. Anyone who has a non-adjustable piezo bridge bass knows what a pain it can be to set them up. Shim the neck and adjust the truss rod. Maybe sand off the bottom of the saddle at the great risk of having uneven volume across the strings. Oh what I would give to be able to adjust individual string heights at the bridge. Here is the problem. I shim the neck and adjust the truss rod and get the action low. 95% of the action is great but there are a few places on the neck, on different strings where there is to much string buzz/sitar effect. Do any of you who have both Allens and Turners notice a difference? Are the necks on one or the other more consistent? Any one tried Acousticores on their Rob Allen ? I recently tried a Allen 4 string and bass NW and the action was very low and even. Wondering if I should switch. I am also aware that one could go though and painstakinly sand out the problem areas but this is an iffy proposition. Thanks for any feedback.
