GHS PRESSUREWOUND The Fourth Kind Of Electric Bass String I had been wanting to try these strings ever since I found out about them, and boy howdy let me tell you what! First, the nomenclature: M7200 - .044G/43.3 lbs. .062D/48.6 lbs. .084A/47.2 lbs. .106E/48 lbs. This string set gets its name from the process that the wrap wire is passed through compression rollers that presses it into an oval before it is wound on a hex core. This allows for a closer and smoother wrap than a regular roundwound string. The wrap wire is made of ‘Alloy 52’ which is 52% Iron and 48% Nickel. This Alloy 52 makes for a very strong magnetic field for the pickups to receive. I installed the Pressurewounds on my 2012 Fender American Standard Jazz Bass with stock Custom Shop pickups and rosewood fretboard. I gave the strings a pretty good workout and they played in quite quickly at about 8 hours of playing time. Tonally, Pressurewounds really sing with a unique voice. They’ve got some serious bottom meat going on with a good amount of solid attack that is almost flat like. Then there is the low mid growl. If you’ve ever heard a really big dog issue a seriously menacing warning growl, this is it. The growl doesn’t overpower the initial punch of the attack as many roundwounds do. In fact they arrive together in a quick 1-2 combination sonic punch-up. Unlike upper midrange snarl that most roundwounds have, Pressurewounds bark. They are clear and forceful. When played aggressively with a pick the mids leap out cutting and edgy. When finger funked, the bootys be bumpin’. This will keep you sitting pretty in the mix. The high end is where Pressurewounds shine as they are so smooooooth. No unmusical uber ringy-zingy wangy-twangy nonsense. That’s just so much noise. Pressurewounds make music with a crisp, clear, and well defined top end. If you pop a note it leaps out with plenty of snap. Pressurewounds are tangy not twangy. There is almost no string noise and glissandos become joyously musical again instead of the repulsive string screech of roundwounds. Finger noise is also greatly diminished. Negatives are few. They are a bit stiff. So if flexibility is important to you, get the light set. I’ve found the .44 G to be too light for my tastes. Sounds fine but I’d like it to be heavier as it would be a better match for the rest of the medium set. I think the E would be better if it were also a bit heavier plus taper wound like the Big Core Bass set. That would be righteous. I’ll be making ongoing comments as this string set ages.
