I just bought a Hammond M3 from a guy for $25. Based on the amount of dust in the back, it is obvious that it has sat in a garage for a while (probably unused). I have some oil on order. When I start it up, the upper and lower manuals play alright. However, when I use the bass pedals (specifically the C and C# pedals), it sounds like both of them are playing at the same time. Also, when the volume button is selected to 'normal', and I play any of the bass pedals, they seem to stick. Meaning they continue to play when I press a key on either the upper or lower manual. If I run my foot quickly across the pedal, it will stop playing with the upper manual.
