1965 AVRI Jazzmasters--what kind of pots are the tone/vol controls equipped with?

As the title suggests--what are the stock tone and volume pots that the AVRI 1965 jazzmaster comes with?

Judging by how it sounds to me, I think at least the volume is linear. To my ears it doesn't sound like a smooth taper--volume jumps quickly from 0-2 (on the knob) and from there on as I turn it up there's little change.

I do not want this behavior--I want 50% volume to be 5 on the knob. Should I switch to an audio taper?

I’ve noticed my avri 65 jag has a sudden roll off between full volume and 8. Especially the highs. The rest of the pot’s travel is fairly uniform but very dark.

I know it has 1 meg pots on the lead circuit but I don’t know the brand. My volume pot was also faulty and had to be replaced, but I know they matched the value at least.

I bought a toneshapers treble bleed kit last week in the hope that it will give me a better tone balance. Hopefully it’ll be here in the next week or so and I’ll report back on whether it helps!

It may also be the fact that the jaguar usually uses linear taper (as opposed to audio) for the volume pot

Oh thanks - TIL. What’s really surprised me is how it’s much more noticeable the treble roll off is through my new class a tube amp versus the class d power amp in my old micro terror.

Unrelated to this thread, but the 60 cycle hum is also MUCH more pronounced. I might need to invest in a noise gate!

Here is a partslist for the AV65. It uses "Fender 1Meg +-10%" potmeters, no 0019066000, which is an Audio-Taper pot both on volume and tone in the lead-circuit

Actually if I'm reading that right it looks like the volume pot (#13 on that partslist) is "Control Solid Shaft 1 Meg Linear", part #0095704000, which is this one. So maybe if I swap it for the audio taper version it'll do what I want.

Thanks!
