[HAM] Leslie 122 Tone etc.

[Bohachewsky, Andrew V.]

Hey Tim,

I have run into a similar situation with a recent acquisition 100% stock
45. I plan on monkeying with some things in the next few days, I'll post
what I find.

My only organ with a 147 type connection is my chop, a '50s wax cap C3
that also has a 760/860 type connection. It's currently adjusted for the
860 which in this case means 1: I'm operating in the low half of the
swell cap range (it's servo controlled so I can adjust the extremes - at
max swell the 860 crossover was overloading, what it really needs is a
resistor pad like the 760 crossover but...) and 2: I have the tone
control almost all the way down. To play with either of those things I
need to do some disassembly (it's in a chop case)... Next few days...

Even with wax caps and these adjustments, through the 860 the treble can
pretty much take your head off no problem. Through the 45 the treble
does seem lacking (it is definitely there with no buzzing or
distortion). The bass sounds awesome though, tight and well defined.

The one last thing is that I have the 45 on a rolling dolly so it's
raised off the floor ~4 inches. Would that make it more bassy? I'll
hafta try that too - actually might be good to know in those cases where
you do need more bass...

Andy

I have a 122 that seems to be too bassy overall.  Is
there a way to make it less so?  The treble speaker is
working.  I have compared it to my 222 and to my
friend's
