After changing the springs,there are two points that you can feel one is the feeling with hands, and second is the tone.

The most different is touch.
The Flexibility of strings is getting better, but it shows in different position of neck.

The lower position (fr.3~fr.7) with sixth and fifth string become very easy to play, bending and blending is getting much eaiser, you can show more emotions int that part.

The middle position (fr.5~fr.8) with the fifth, the fourth and the third response more,

And I think the best part is the high position (fr.10 ~ Fr15) with the third and the second the position.Sunddenly, you feel you can do anything is that position, the hummer and pull and also easily done well.

So,because the feeling with touch changed, it enhance my performance,I suspect the influence in tone is not because of the spring,so I record clean tone and distortion in open strings.

Each open string sustain more, especially in the lower string.

The volume is part of the largest changing, six string averagely increased 0.5 ~ 1.3 db.

The best part is tone.It sounds like you remove the rusted strings and change to new string.Each strings increase the sweet frequency.

In distortion tone, lower string become more strong, you can do feedback anytime as you want.

In clean tone, also with the high frequency, the sounds become significantly brighter, like you removed the cloth coverd in tone suddenly.
