The "new era" Danelectro company made a line of guitars (Dan-o-blaster) in the early 2000-era with built in effects. The on board effects of course remind one of Electra's MPC range, so I think it's worth mentioning in this forum.
I've just acquired this Dan-o-blaster Innuendo 12 string.
The body is atypical for vintage and reissue Danelectros, in that it's "solid" (plywood) instead of hollow construction. Kind of a mashup of strat and Mosrite shapes. Basic strat style three pickup w/ 5 way switch, master volume and tone controls. 4 small push buttons activate individual effects (distortion, chorus, tremolo, and slap echo). Two more knobs allow modification of distortion and term rate. The other effects are non-adjustable. Uniquely, there's a direct output jack that bypasses the effects, while another output jack activates the battery powered circuitry and provides the effected output. You can use either output, or both simultaneously.
The clever bridge has adjustable intonation for all 12 strings, and the guitar has nice enclosed mini tuners and graphite nut, with medium frets, and a relatively comfortable string spacing. Read: less cramped than a Rickenbacker 12 string.
