Electronics can be upgraded without having to send the whole instrument!
(1) Remove the backplate.
(2) Disconnect the pickup wires from the pre-amp board - they are snap-on connectors, check the FAQ section of the Club.
(3) Remove the knobs - you will need the proper tools for this, so ask Mica if you need the details.
(4) Loosen the pots, the switches and the jack, from the top - this releases the whole electronics package, so make sure it doesn't drop.
I had the pickup selector on my Spoiler replaced with a blend pot, and the two-position 0/8 dB Q switch with a 0/3/6 dB one. You might prefer a second volume over a blend, or a 0/4/8 or 0/6/9 Q switch, but any one of these would be an upgrade.
If it's an older Spoiler, the existing pots may have narrow shafts - the pickup switch certainly does, so you may need to drill out the holes to accommodate the new pots. Make sure you discuss the exact details with Mica.
