Magnum 1 - eccentric "potato" shaped body (inspired by the Deacon and Breadwinner axe-shaped guitars), twin pickups, passive circuit with mono and stereo outputs.
Magnum 2,- as above but with 3-band active circuit (6 graphic sliders supposedly keep volume output constant when adjusting EQ), mono output.
Magnum 3 - as model 1 but with more traditional double cutaway body.
Magnum 4 - as model 2 but with more traditional double cutaway body.
Magnum 1 is my favourite (I have a factory fretless one) - love the original body shape, and the active circuit is known for being noisy and hungry with batteries. All fab bases though!
