CTS pots are more expensive to buy, but will probably outlast your playing career.
There’s a lot of cork-sniffing about ‘orange drop’ caps or ‘tropical fish’ caps etc... but any capacitor if 0.047uf will do. Small tantalum ones will have a code of 473 printed on it somewhere, a polyester box cap will have .047 printed on it. The bead ones have the advantage of being smaller (so they fit into the cavity much easier) and have longer legs, so they’re easier to bend into whatever shape you want.
