As per the title. My primary concern is that the strings sound balanced and even between them. If they thump, they all thump. If they get thumpy as you go up the neck, they all get thumpy. If they sound warm, they all sound warm (after break-in, of course).
To my ears? Yes, they are very well balanced, sound-wise. I'm not overly concerned with balanced
tension, but I am concerned about balanced
tone. I've had a set of them on my '13 Gibson Thunderbird for a few years now. They are smooth - like La Bellas - but, while they
are in the "Old School Flats" camp? To my ears, they're not nearly as "Old School" as, say La Bella 760FS's are. The Dogal's are pretty well balanced, tone-wise. Very good low end; nice low-mids, but a little more mids than La Bellas; and definitely more top end. Pretty similar to the Optima 4099L "Chromes" that I have on my '06 Carvin LB-20 and my '88 Tokai TB48 Thunderbird, IMO... As for their sustain? IME, that's more a function of the bass itself, than it is the strings. Every kind of string I've ever put on my aluminum-necked '78 Kramer 450B, sustained enough to drive a person mad. Including the La Bella 760FS's it's wearing now... The Dogal R44's on my Gibson T-Bird have more than enough sustain to suit me; in fact, I'd be happier if they sustained a lot less...
Regarding the Dogal "Jaco" Carbonsteel Flats? I have a set of the JC106A's on my '73 Rick 4003; more for their ridiculously low tension than anything else. That bass has neck issues that older 4001's sometimes get, and I need super-low tension strings on it. They certainly don't
feel super-low tension, though; in fact, they feel a little stiffer than the TIJF's on my '95 Alembic Epic. To my ears? They don't sound much like TIJF's either; in fact, they sound a whole lot like the Optima 4440 RB Flats on my '01 Rick 4003. Which makes my very happy, since the Optima RB's are re-creations of the original Maxima 4440 Flats that old Ricks used to wear from the factory. Which is a tone that I like - a
LOT...
