Not too much. I plan to finish my Warmoth build for a 5 String Deluxe Jazz J+MM. I've had the body since the summer of '18, I ordered the neck finally in Dec. I'll order pickups and preamp in about Feb-Mar, then a few other odds and ends needed.
Evaluating an amp purchase, I might buy nothing, or I might end up moving my vintage tube Bassman in favor of a Rumble 500 combo, tried one and was extremely impressed.
There is one effects purchase I want to make, some kind of modulation pedal. Reverb, delay, chorus perhaps. Not 100% set on what it will be or if anything will work. Trying out an Afterlife Reverb first, will see how it goes.
Otherwise my only other plan is my NEXT guitar build for a '54 style P with split coils. Would like to start ordering pieces late in '19.
