Bernunzio, is where I purchased several sets of the Dogal's from. But that was a year or two ago. I did notice that they no longer list them on their website, but that may be more due to the high cost per set, resulting in the low interest for them?
They are not very well known, if at all. And they are probably the most expensive E-bass, string sets out there.
I've had the traditional sets, and the Jaco, series sets as well.
The traditional flat sets are very similar to chromes, but have a better feel, and they seem to retain their initial brightness longer than chromes.
By better feel, they feel slightly less stiff and have a smoother polished surface than chromes.
The Jaco, series are very similar to TI, flats with a hair bit more tension to the feel. Sonically, they are very similar with the main difference/benefits being that the Jaco, series are offered in a wider variety of gauges vs the TI's. They behave and have so far retained their characters in much the same traditional way that the TI's have.
The round sets, are very similar to DR's but with a smoother finished feel to them.
Bernunzio, may still be the best bet for ordering a set. I'm sure they will oblige if they can. A quick phone call may do the trick, ask for Julie
The Dogal's are very high quality, hand made strings.
Obviously, not for everyone at over $100 per set.
But so far, they do seem to settle in and have the same staying power as TI's.
So in the long run, the initial cost outlay was a similar investment deal.
