Got a FG4003 a few months ago.
Love that throaty, growl and punch. Growlier than my P.......n and S...fire basses.
Found myself having more fun and playing more, like when I was a kid and played my axes because they were so much fun and such a new thing and great sound.

Well, after a month, I decided to put my usual flats on as I have only played flats for years. Love the silence when I move my left hand. No squeltch.

Well, the 4003 sounds great, both the LaBellas and Rotosound flats sound good. But not much growl and punch. For fun I tossed the ric strings back on. I'm 14 again and having so much fun with the intoxicating growl and tone again.

So I might just keep rounds on the Ric for the nice tone I like when it has rounds on it. I might just keep it as my rounds bass.

But on to Chromes first! Gotta exhaust my options before I surrender!!!

So...
I've had a MG4003 for a little over a year. A few months back, I replaced the strings and was determined to stay with roundwound. I too went with RotoSound but went light 40-60-80-100.

Being new to owning a 4003, I would like to know what round wound gauges you all recommend...

What brands you all use as well.

When I purchased my 4003 last year the first thing I did was to replace the stock SIT Roundwounds with TI Flats. It sounded great but you do lose that characteristic growl, then a couple of weeks ago I put the stock SIT Roundwounds back on and bingo that is the sound I really want my Ric to make.

So...Ric uses SIT on they'er factory 4003s?

I use SITs on my other axes...

Do you have an item number for these SITs? Thanks!

Sorry mate, but I don't have the item number, but the gauge sizes are 45-55-75-105. I think that you will be able to find the item number going off the gauge sizes in a browser search.
