I have a newly aquired Spector Legend 4 I bought used and I have a problem with the volume controls. Starting from the "off" position on both volumes, the knob travels almost an 8th of a turn in silence, then the sound cuts in suddenly at a fraction of it's total volume. The volume rises gradually from that point, but not being able to fade in from silence is bugging me. An instrument of this grade shouldn't have shoddy electronics, so I took off the cover and had a peek. The top and left pots are the volumes. It looks like the original pots have been replaced with Alpha B500k pots. The solderjoints are messier than on the other two pots, so I'm convinced the previous owner tried to mod the bass. Can anyone with a spector legend out there tell me what pots I should have? I'm pretty disappointed in the sound quality of this bass in addition to the volume issue, and I hope changing the pots back to whatever they're supposed to be will fix it. Thanks in advance for any information anyone can help me out with.
