Hammond L-122 into Guitar Amp?

Post by warwick.hoy »

So I inherited a Hammond L-122 Drawbar Organ with the house we moved into. If it were a B-3 or a CV I'd be stoked but it's just an L-122. That said it does have a little mojos all on it's own and it would be cool to have a functioning Hammond Organ in the house; but I'm not really an organist so,....I was considering gutting the amp out of it and modding it for guitar purposes.

So A) does anyone know if thing is worth anything or if I should just leave it as is?

and B) if I were to make it into a guitar amp,...does anyone have any idea how to go about that without killing myself? Links are cool. I did a search but didn't find a great deal more then discussions that said "don't kill yourself".

meh... I would just leave it......... I don't think you would get any "special" sounds out of it... and just having an organ around increases the coolness factor by 10³.

if it has a rotary speaker then you should jump on rehousing that bitch.

you can make a drone box out of a tonewheel organ pretty easy. run all the signals from the tonewheels into a giant passive mixer or a fixed resistor network if you want to save money. you can use a vactrol and a pwm controller to get modulation on the tonewheel motor. maybe just stick vactrols in the passive mixer to modulate volume. you can use a DIY version of a pickup winder sensor hooked up to a frequency divider to extract LFO from audio at 16 octaves down. an optical sensor on a perforated wheel would also work. these are all similar to the sensor wheel in an old mouse or the speedometer on a bike.

I do understand everything I said. people often get intimidated by me and how I speak. that is unfortunate. my intention is to share ideas with like minded people, I'm not just doing it to look smart. I would love to do a project like this but your all the way over there in seattle. I love drone music and I love electronics. I would make sweet sweet love to that organ and leave it with its guts hanging out.

to elaborate a little on my first post. I'm just talking about making simple cheap mixers with pots or resistors. vactrol refers to a an LED glued to a light sensing resistor. you probably have one in a tremolo pedal. they are less than $1 to make. a frequency divider is not anything to be scared of. they are $0.32 at tayda. ok now that you have your low frequency square wave, you can feed it to your vactrol and your vactrol controls the volume. you get a "wowowowowow" sound. thats a drone for less than $5. dont hate. build something.
