Just looking at photos of the Washburn DD60, it has very similar-looking trem as the JT590 trem on the Rhoads Student you just bought. Both are Schaller designs with the closest OEM product being Schaller's own "Schaller Tremolo" that ed linked above. The OEM page is here: https://schaller.info/en/tremolos/359/schaller-tremolo
I don't know your current comfort level with trems and disassembling parts, but if I were in your shoes, I would diassemble the JT590, inspect the various components for wear (especially looking at the screw holes on the baseplate and seeing if they are reinforced with steel inserts, or if they're bare zinc and stripped), clean everything with WD-40 or 3-IN-ONE Multi-Purpose Oil and a toothbrush, and reassemble it. It's just part of the normal servicing and setup that I perform on all used/dirty guitars that come into my possession. Actually, if you're "afraid" of a trem, doing this might ironically have the positive effect of familiarizing yourself with the trem and you'll gain a healthy respect and understanding of how it works. Everything is adjustable and reversible, so don't be afraid to "mess up the existing configuration". Just disassemble carefully and sequentially to keep the parts arranged accordingly and neatly on your workstation. An example of the neat arrangement is pictured below, one of my Ibanez Edge trems disassembled across a towel. The saddle blocks are still inside the saddles, and the intonation screws are together with their washers, so the bridge is not technically 100% disassembled... but everything else is in individual pieces and arranged in such a way that I could probably reassemble everything in the dark, like a soldier reassembling a rifle without the aid of sight.
