Review: GHS Round Core Bass Boomers

Fresh out of the pack, these strings are an absolute pleasure. So harmonically rich in every sonic dimension they put a smile on my face right away.

GHS released their Round Core Bass Boomers at Summer NAMM 2014, so they are a little over two years old now. Not much has been written on them, until now.

With most roundwounds it's the top end that gets all (or most of) the attention. In his video @Jon Moody states that the top end has a soft glassy sheen. I like that and will go with it. The highs sing sweetly and are soft and airy with nary a zing in these strings.

The low end attack combined with low mid definition are the stars of this show. You actually get some gut level punch much like a flatwound as the attack isn't covered up by growl. Yes, these strings do growl but it isn't overbearing and unbalanced and muddy as in many other company's sets.

I like a meaty midrange, and GHS never fails to deliver the prime bass meat. Between the attack and the sustain it's the mids that bring home the beef. They are tasty and harmonically rich in overtone gravy.

The string-to-string balance of tone and volume is super sweet! If you play any cords or do any two hand tapping these are the strings for you. Here is also where the harmonic richness asserts itself with deft aplomb.

Balance of feel is good, and just as you would expect from a round core these strings are a bit more flexible than their hex core brethren.

The winding is fairly smooth like all Bass Boomers. They're roundwounds so yes there is string: 'talk'; 'chatter', or more accurately screech. But less than many other brands.

I didn't think there would be that much difference between cores, but there is enough to give GHS Round Core Bass Boomers their very own pleasant sonic personality.

I'll place compare & contrast posts between hex core Bass Boomers and Pressurewounds later in this thread.

Interesting. How would you compare them to DR Sunbeams?

I haven't had a chance to try the Round Core Boomers yet, but based on their description by @Linnin and my experience with the Sunbeams, I would say the Boomers have punchier mids, while the SBs are slightly scooped in comparison.
 
For what it's worth, I have found DR Sunbeams to feel and sound very similar to GHS Pressurewound.

My experience is different...

The Sunbeams are all about the full, warm bottom with a smooth but still bright top end, while the PWs have tighter lows and punchier mids. To my ears, the PWs are closer to the Nickel Lo-Riders both in sound and feel, both being hex-core.
 
Here's an interesting quote from another thread.
I picked up a set of these after asking Jon quite a few questions about them. I was a long time TI Jazz round user but eventually the price made me give those up and try to find a more affordable alternative. After testing a bunch of sets I settle on DR Sunbeams as the closest I could find. I decided to give these a try and not only do I have a new favorite but I am positive these are the best alternative to TI's that I have found. I always liked the lower gauge of the TI's but went with a 100 set in the Sunbeams because the 95's were just way too low tension for me. With the GHS RC Boomers I can do 95's easily and they seem to have equal tension to the Sunbeam 100's. I would say that anyone that loves TI Jazz Rounds or currently using Sunbeams should give these a shot.

The GHS Round Core Boomers have far more mid content particularly in the low mids and are not scooped, resulting in a fatter and more authoritative voice. Tension is higher but comparable to most common strings yet with the give of the round core. Texture is also smooth. Top end character while not as bright initially is just right and lasts longer. Overall audio profile allows them to cut much better. While I haven't logged a ton of hours on them yet I can say already that they last longer than Sunbeams.
 
Hmmm...I think I may try these on my Stingray. I am normally a HiBeam user, but I recently put a set of pressurewounds on my Spector and they really work (IMO) with that bass. So as a change of pace, I think I might try these.

Edit...just ordered a set!

Put a set of these on one of my P-Basses. Loved the tone right out of the box. two weeks later there were very different strings. They became, dull, lost there magic.
Went back to Sunbeams. They keep there tone much longer.

This simply indicates both the Boomers and the Sunbeams are living up to their respective names.

The magic of the Boomers are in the "boom", not in the "zing".

The "sun beams" are supposed to be both warm and bright at the same time.
 
Very cool review thanks for taking the time to write it. I have a set in my closet Jason at (bass strings online.com) had a sale and I bought a set but I haven't had a chance to use them because my regular Bass Boomers aren't close to wearing out. I love GHS rounds because they are inexpensive, great low end, smooth high end with a great G string and the string noise is so low I forget they're rounds. :)

Same here - going back to regular boomers - I Loved these strings - dead in two weeks
