I'm looking to replace the pots on one of my Les Pauls (Not the Epi) and was looking through the website where I buy from (Thomann, Germany) and came across pots that have short and long shafts. Which are the Les Paul ones? Are the volume and tone ones the same? 250, 500 K ohm or 1 mega ohms? Whats a good brand without breaking the bank? What about caps? Thanks in advance .
