I went on a trem pedal journey a while back and what’s ended up closest to the sound in my head was a newer boss tr-2. The ones post 2007 have a small trim pot inside for volume and come factory set with a small boost to compensate for the perceived volume loss. It’s simple and no frills but man does it sound great. I also have the source audio true spring but I just use that for reverb. The trems on that do sound super cool though.
