I recently received my strap from Karl. I only waited 6 days from order to delivery. Fantastic for a custom piece. It looks fabulous in black with black stitching. I suffer from shoulder problems which I receive treatment for. I've been using the strap for 3 days now without any of my usual aches. That included a 3 hour rehearsal last night. The strap does not slide on my shoulder thus securing the bass at my preferred angle. I use a heavy Sandberg and for the first time I'm not aware of its weight. I thoroughly recommend this strap. Great quality.
