Here's a standard bridge I beveled down the ebony, put on iron wood quarter sawn over the remaining ebony with Crazy Glue. The 3rd and 4th strings were too bright with iron wood, so I retro'd ebony back on to those slots. Also angled the bridge, and that seems to have increased the punch.
The tone ring in this Good Time cost $1.75 at the hardware store, plus 5 cents worth of JB Weld. I think I saw a thread on this here. After hand bending the galvanized steel rod, cutting it and gluing it, I hit the glue joint where the galvanized coating had been sanded with clear acrylic nail polish to prevent future rust. I think the Good Time is set up for a tone ring, as it all came together on string heighth re: setup after adding the tone ring, in addition to vastly improving the overall tone. Additionally, a channel is routed toward the inside of the rim to receive a tone ring. The tone previously was uneven, now with this setup it sounds very even in volume and appropriate string by string in tone.
The mute you see is packing foam rolled up. Works just fine.
