On my bass for about 1 year. All are in good condition but the extension E/C broke where it was apparently either catching on something or there was a manufacturing defect (see picture). Jan-Ole offered a discount for replacement, and told me this one would be fine to use on a bass without extension, but I only have one bass, and the discount wasn't sufficient to justify the purchase. These should have lots of life remaining. I have since returned to Oliv/EPW, and will remain with that combo for the foreseeable future. Shipping to CONUS included in price.
