I've not got much 1080 experience (I had the 880 for a while though, that machine sounded beautifully haunted haha) but both the 1080 & 3080 are 32Khz-based (apparently) and share the same screen size so I imagine it would be pretty similar? Of course the 3080 has over 1000 waves, including a bunch originally from the JD-990, and a handy smart media card reader. Mine came with a 64MB card which is a lot of space for patches.

Although, of course, most of the JV/XV weird magic comes from ringmod/booster & FXM (I'm currently filming a demo vid!) the 3080's new effects are a huge part of the draw for me too. Here are some highlights:

Formant Filter, an Extra Ring Modulator with volume follower, Reverse Delay, LOFI Noise (with radio detune!) and a handy Speaker Simulator. I hear the XV5080 has even more effects (COSM) so maybe one day I'll check that out.

£230-ish I paid? No brainer. I'll likely sell my XV2020 now, which has the extra waves but not the extra effects, and needs a computer editor.
