This is the internal wiring material that we use for repairs, and it has been very well-received. We have carefully selected wiring materials to suit a wide variety of guitars and basses. However, we found that the ideal wiring materials for guitars and basses are few and far between, and this is one of the valuable materials we have encountered. The sound quality is highly resolving and transparent, without any strange quirks, and offers a natural sound. Compared to the Belden #4 also on sale, it has a slightly sharper sound. It also expresses nuances delicately. Although it is a vinyl wire, the sound quality is quite good. This is a popular wiring material for customers who want to keep costs down. Changing just one wire from the volume pot output to the jack will make a huge difference. It is especially ideal for ground wires. Those who have never tried vintage wiring materials will surely be surprised. You will be able to hear sounds you couldn't hear before, and sounds that were vague in the depths of the speaker will jump out in front. Please experience the difference from modern wiring materials. A blend of #2, #3, and #4 also produces a very good sound quality. Please use vintage solder. This is sold by the meter, but if you purchase multiple units, we will send it uncut. We have received many inquiries about wiring materials, so we are offering a larger quantity. Thank you for your consideration.
