It really does matter, this is what I use they are not expensive and the difference between this and just about any other capacitor is the others will just cut frequencies, with one of these vintage bumble bees your tone remains Musical as you roll through the tone knob, it's very easy to switch as some people here have mentioned, just try it and if you've got reasonable ears you will absolutely hear the difference, .01uf is the value Hamer used and it's a good one
Another good free trick is making your tone pot no load, there are videos on this it's very easy, I could convert one to no load in about 1 minute now
there are a bunch of harmonics and goodness that you can hear when the tone knob is out of circuit, Eddie didn't use one! But if you want to use it the slightest turn counterclockwise it comes right back into circuit and then you've got the full range like normal
