Hello,
I bought the kit from Musikding as well and it is exactly what is described above and maybe a bit worse. I have tried it with 3 basses both active passive, EMG.
Going to Ec electronic BQ500 and tehn 2×10 cab, OR a small Ibanez practice amp.
5V on all J113 and 4V but still the same issues. Also I put in serial another set of resistors on the 1k ones (3,6k+1k). Nothing was improved, I again did thte bias to 5V. This time when started with the new resistors the Voltage was 7,5V or so.
I will try tomorrow the 6.8KOhm but i think then there will be an issue with the trim pots since with the increased resistance the lowest was 5,3V/4,5/4,5 respectively. So with 6.8k iwould expect the min Voltage to be higher.
Any other suggestions?
Thanks
