And now... The result!
Instead of cutting the leg on the pot, I removed the track joining the leg back to the wiper, and added the wire as shown. And... The bass control, far from exhibiting the classic top boost feature, didn't work at all... It did nothing.
So I reversed the change and paid more attention to the existing top boost eq.
To be honest, because I have more than one amp to use, I hadn't really experimented much with the AC4C1. The eq section seems to work with no effect in the centre position, but with boost or cut from that, depending on left or right rotation, whereas the "classic" behaviours as exhibited by the AC15HTV Heritage is no effect on minimum, but increasing boost with clockwise rotation.
And, strangely, on the AC4, the "sucked out middle" phenomenon now appears on the treble control approaching maximum boost - and that's where the Burns era sounds lurk... With Strat or Marvin.
Show it. Les Paul, however, and some gain,,then turn the guitar down to 3 and clean rhythms are there. Turn in up and it ROARS!
