http://www.daddyslide.de/index.php/en/So I purchased a slide from these guys. I must say, I'm entirely delighted. The process of buying is somewhat collaborative (they are very knowledgeable about slide guitar) and the final slide I received is very well made.
Its blend of the dimensions of my copper pipe slide and RockSlide, but with heavier and thicker bronze. The tone is excellent as is the sustain and its an absolutely perfect fit for me.
40euro isn't cheap for a slide in these Brexit times, but considering the results I find that price highly reasonable.
On a personal note - its rare I
don't play with a slide at the moment.
