Sweet pickups. They appear to fit in a standard single coil slot. Active, obviously, with the knobs becoming frequency boosts rather than rolling off frequencies. Can't make any comment on what it would take to wire them in the Carvin model you have, but there is lots of room in a Strat. If they are similar in design you should be fine.
...so ever since then, I always hang on to the buckle.
