GHS Strings Brightness Bar for Electric Bass Guitar Strings

GHS Strings Pressurewound Bass Strings

GHS Pressurewound Bronze strings are an exciting development for acoustic basses. For many years, players have loved the volume and tone of phosphor bronze on their acoustic bass guitars, but absolutely hated the string noise that resulted from it.

To address this, the phosphor bronze cover is run through precision rollers during the winding process, slightly flattening the wrap. This results in the first phosphor bronze bass string that does not have harsh and abrasive overtones and finger noise, just a smooth mid-focused sound. Add balanced construction and a round core into the equation for a truly unique acoustic bass sound.

Pressurewound Bronze are also designed in such a way that they also work well with electric basses.

Why Should You Play Pressurewound Bronze?

  • You love the tone of phosphor bronze strings, but hate the noise
  • You're looking for the clarity and nuance of your acoustic/electric bass
  • You want a unique sounding bass string for your electric

Do these come in 45-105? Thanks

The 4 string set I have is incredible.


I would like to echo the opinions of others; more gauges! 

I have a custom 7 string acoustic bass, 32-30” fanned fret that sounds unbelievable with these on. However, a 120 low B, even with the material adding more mass and therefore tension, is toooo small (even on a 34” in my opinion, let alone anything smaller).


I would give my right foot to be able to string my Acoustics, from 4 - 7, with these… and actually my electric 4 - 7 too.

I have enjoyed these a lot on my Furch 5 string long scale with low B tuning.  Any chance at all you will be making a short scale 5 string high C set (or even a short scale 6 string set would work)?  Would love to put them on my Kinal Kompact.

Hi Ken, that's always a possibility. We'd have to do some research to see what kind of market would be out there for such a thing and go from there.

Being a flatwound player, I was expecting these to be flatter than they where. That's not a bad thing though. When I got my Fender CB-60SCE (which came with Fender 7060 Phosphor Bronze Acoustic Bass strings), I replaced the strings immediately. I wasn't expecting the "nails on a chalkboard" sound that came with them. Plus, they were heavily corroded right out of the box. I replaced the strings with La Bella 750G Deep Talkin' Bass Gold White Nylon Tapewound strings. While this instantly eliminated the terrible sound, the tension was so low that I felt like the strings were just laying on top of the bass (heavy exaggerationI). I chose those strings because of the reported brightness. This was totally true. But, since I dig in way too hard (I'm breaking that habit thanks to my compressor), i kept fretting the strings off the sides of the neck. I also had to play much harder if I wasn't playing on an amp. 

Saying that, I knew I needed a higher tension string, but didn't want to lose that acoustic sound. I didn't want to go back to the "bag of cats" screeching sound though. This is where these bad girls come into play. The tension is much better than the tapes, but, like I said earlier, I thought they would be flatter. For a second, I thought I was sent the wrong strings in the right packaging. I think I was expecting halfwounds. Needless to say, my eyesight is crap. So, I took the snips from the end, and took a picture with my phone and blew it up. Never trust your senses lol. They're much flatter than roundwounds. The best part about this? No finger sticking to flats from the extra surface area and heat from the hands. So, now I get the bonuses of roundwounds with less noise. 

Being a noob at this, is there any tips anyone can give me to avoid corrosion? Anytime I'm window shopping or am in forums, I'm going to recommend these strings for acoustics, without a doubt. If I wanted to hear annoying screeches, I would call my ex-wife.

Hi Larry, I'm glad you enjoy the Pressurewound Bronze so much! They're definitely "rougher" than a set of flats, but still very easy on the fingers. And as you said, no "nails on the chalkboard" harshness or overtones! I can't stand those either. 

Sadly, phosphor bronze strings are going to tarnish; it's the nature of the material. You could keep them wiped down and clean, and put the bass in a gigbag/case when not in use and that will all help delay the process. Thankfully it doesn't affect the sound of the strings.

GHS Bronze Pressure wounds are the BOMB! I have them on 3 of my Basses and I'm ordering another set for a 4th. The tone is somewhere between mellow and a growl, considering how pluck the strings, I can get any sound I want!

Exactly what I was looking for, strings that have multiple personalities!!

Jonathan Moody

I appreciate the kind words! A lot of thought went into that set, and I'm glad that it's been so well received.
