[HAM] Leslie 122 Tone etc.

[David Anderson]

Tim,

There are a several possibilities. One is that the stock woofer in the bassy 122 has been replaced with something more efficient. Another is that the crossover capacitors may have drifted. I replaced the original capacitors in my Leslie 44W, and it brought out highs that had been obscured by what I think was a large increase in dissipation factor in the capacitor in series with the horn (nominally 7.8uF). I recently bought an Impedance Bridge, and the DF of that capacitor was VERY high.

You could also try switching amplifiers and/or seeing if someone has modded the amplifier in some way to roll off the highs.

Also, are you listening to all of these cabinets in the same size room? Even location in a room can greatly change one's perception of bass intensity.
