I just bought a Brice HXB 406 6 string bass. Sort of as a fun project to modify and to see if I can actually get used to playing one of those beasts.
The bass is fairly light. 10 pounds or so. I noticed that the neck feels pretty heavy when I sit down without a strap.
I'm wondering if that is just the nature of 6 string basses or if there are some that are better balanced than others.
I wouldn't say they are all neck heavy...
Already mentioned by other poster, most 6 string basses have top horn strap pin position parallel to 12th fret, which I'm guessing you've already realized when you put the strap on that it wouldn't feel neck heavy. Thus, set the strap length so that the bass will not change position between playing it while sitting and standing.
Playing 6 string basses on one lap while sitting down without a strap would likely make them feel neck heavy. But, as depicted by
@gebass6, if you would position the bass in between the two laps, just like classical guitar playing position, then no neck heavy would occur, even without putting on a strap.
One cure to neck heavy basses are swapping the tuners with lightweight ones. From available online pictures of the HBX 406, seems the Brice came equipped with die cast tuners, which most likely licensed Gotoh GB7 tuners. I weighed the licensed GB7 that came with my Ibanez basses, they were 60 grams each. They aren't the lightest tuners, but they are significantly lighter than BT4S tuners used on some Fenders.
The currently available lightest bass tuners on the market are either Hipshot Ultralite (lic'ed = 49 grams, USA = 42 grams) or Gotoh GB350 Res-O-Lite (40 grams). But they might not be economical solution for low priced basses, especially that the GB350s are quite pricey.
- The
potential is probably higher to be neck heavy. 2 more tuners, and (maybe) a bigger head stock certainly wouldn't help...
- The increasing use of lighter body woods, coupled with 2 more tuners, etc., etc., wouldn't help, either...
Like any other type/style bass, I'm sure there are 6-stringers that are better balanced than others. But, I don't know which ones they are; sorry. I'm sure there are lots of folks who do, though... and one showed up as I was typing this, in fact.
Agree on the increasing use of lighter body woods. They don't counter balanced the increasing mass of the neck that well, so neck heavy might occurs.
But regarding the additional tuners... as mentioned by other poster, most modern 6ers came with lightweight tuners, thus the 2 more tuners could mean nothing, i.e.:
- 4 string Fender Precision and Jazz Deluxe BT4S tuners, 123 grams each = 492 grams in total;
- 4 string 1966 - 1982 Fender basses Schaller tuners, 110 grams each = 440 grams in total;
- 4 string G&L Musicman and Fender Mexican tuners, 95 grams each = 380 grams in total.
vs.
- 6 string Brice HXB-406 or from my personal experience, Ibanez SRFF806, which came with (licensed) Gotoh GB7 tuners, 60 grams each = 360 grams in total;
- 6 string Cort Artisan A6 with (licensed) Hipshot Ultralite tuners, 49 grams each = 294 grams in total.
