Darkglass Harmonic Booster 2.0 Clean PreampThe Harmonic Booster, Darkglass Electronics' first circuit, was meant as a gain stage for distortion pedals but evolved into a powerful clean pre amp. It allows bass players to boost volume and shape their sound without adding distortion. Each volume and EQ control provides a 20dB clean boost or cut, along with a parametric mid control. The unique Character control flatlines the signal when off but adds low end beef and high end sparkle when turned

Works like original equipment
Size: 16 Line Spools+4 Caps
Seems to handle the same work load as the manufacturer part. Good quality fit and design. No problems installing the string on the trimmer head. Definitely worth the purchase.

It was delivered next day
Size: 8 Line Spools+2 Caps
If it's like the previous line I purchased, it's good.
Don't leave it in a hot garage, because the line will sometimes stick together when you get around to using it!
NOTE:
Again, I received this product YESTERDAY, and Amazon is sending me a survey today!! What AMAZON brain surgeon thinks that this is a good idea????
