I recently picked up an old CIJ Mustang and am enjoying it, but the volume and tone knobs are a little bit scratchy and roll off way too quickly. 75% may as well be 0%. Do you guys recommend replacing the pots, or might they just need a cleaning? If replacing, do I need mini pots or would a standard size fit? And any idea if the stock pots are 250k or 500k? (I wouldn’t mind opening up a little more treble if there’s any on tap)
