My Bolsa Bass has developed an issue with the sweep of knobs 1 and 2. It’s most obvious in green mode, previously turning knob 1 would yield a linear response to the filter cutoff but now most of the sweep is localized to the upper range of the potentiometer. Both knobs have the same problem in all modes, however the tune and volume knob are normal. I tried replacing the pots with new identical parts but unfortunately the issue is still there. Is this fixable? I really love this instrument and would love to get it working normally again.
Same issue with mine except its knob 2 and 3
Havent changed the pot yet…
