Dear Valued Customer,


Due to an overwhelming influx of orders, we are currently operating at full capacity, working diligently around the clock, seven days a week. Even with the addition of new team members, we are committed to maintaining our high standards of quality. You, our customer, are our top priority.


As a result, most of our products, including the one you’re interested in, now have an estimated lead time of at least three weeks, potentially extending up to four weeks. We are considering hiring two more team members to help minimize wait times, but for now, we want to ensure you are fully informed.


If this wait time is not acceptable to you, we kindly ask that you refrain from making a purchase at this time. By proceeding with your order, you acknowledge and agree to the wait time of up to four weeks for our hand-crafted, high-quality harnesses made in the USA, with a meticulous live QA process.


We take pride in producing beautiful products that exceed expectations, and we believe the wait will be worth it. Once we return to our standard five business day turnaround, we will remove this notice. If you are reading this message, the extended lead time is still in effect.


Thank you for your understanding and patience. Now, please continue reading about the product that brought you here. A few weeks is a small price to pay for the exceptional quality you will receive. Feel free to check the feedback from our satisfied, repeat customers here and on Reverb.


Thank you,


Pro Tones

This harness will ship with solid shaft pots unless you express to us same day of purchase you would preferred knurled. The phot represents a harness that we just made for another delighted customer, but he asked for knurled pots because of his knobs. If we don’t hear from you, we ship this with solid shaft pots, so the knobs will need to be the screw-on type. FYI.


No refunds on anything that’s been soldered.
