Spirocore Light, (Weich), very nice strings
8 out of 10 found the following review helpful

Pros: I got the light, (weich), set. Still loud, like the normal, (medium) set but not harsh or metallic sounding. They are much easier on the fingers due to the very low tension, (several pounds pull less on each string than most other sets). They bow very easily with a warm clear sound, very expressive. Pizz playing, which I do mostly they give a clear round fundamental tone, but with good 2nd and 3rd harmonics present, making for a fat round sound. So overall they play like gut strings but sound fatter and rounder and bigger. Very warm and clear.

Cons: None really.

Other: If you are used to playing gut strings, then these light spiros will feel very slim under the fingers. However they are very elastic and flexible like the gut.

I love Thomastik Spirocores

Pros: Great strings - excellent for jazz pizz. Work ok for arco, too. Love these strings and have the equivalent on my two bass guitars as well. Thomastik strings rock.

Cons: None - as far as I am concerned.

Superior strings for ease of playing.

Pros: Have been using Spirocore mediums for years then after a 20 year break from Double bass playing have returned with a new Wilfer Lion Head 3/4 Bass and after lowering the action fitted Spirocore Weich strings. They are just so good giving a much lighter feel and brighter with more sustain. Simply put they are the best for jazzing! They arco well too and facilitate faster passages. On the Wilfer bass the tone is just amazing. Not cheap though.

Cons: Price.

Spirocore, a classic all round double bass string

Pros: I purchased the strings for my electric upright bass and found them to work pretty well on it. I used to use Spirocore hybrid strings because, although I'm a jazz bassist, I do a lot of bowing and thought a hybrid string was the best option. I found the classic Spirocore works much better and responds to the bow movement quicker.

Cons: Can't see any particular down side to them, excluding the price of strings in general.

Spirocore Weich bass strings
0 out of 1 found the following review helpful

Pros: I'm principally a jazz bassist and this is my 2nd set of these strings. Previously I used Pirastro Flexocore - a good string but a lot heavier. The soft Spirocores give a good sound, bright but not lacking in warmth. They are a lot easier to pluck and sustain and softer on the left hand too.

Cons: They seem quite expensive - a set of strings is a big investment, so I tend not to experiment too much with different bands and sets.
