Custom Modifications for Tonewheel Hammonds
This is a selection of mods that I have done for my own collection and for clients (subject to model of Hammond, the below suggestions are based on a 3 series Hammond);
Line Out (with or without level control) Balanced (XLR) line out for hum free long runs to effects or mixer
Bass only line out for further sound reinforcement either to mixer or a sub
Line In to run anything from a Strat to a Rhodes to a Nord through the organ preamp and signal path so eq (if fitted) and reverb etc affect the sound. Volume of aux instrument is not affected by organ swell pedal.
Relay to allow low voltage (with synth footswitch jack) Leslie switching (Also allows up to four different types of Leslie including Neo Vent to be switched simultaneously). You could alternatively have a swell pedal mounted kick switch.
Active tone control (bass and treble boost, gain adjust)
Discreet LED pedal light strip (any colour you like)
Effects Loop - Add a wah, EQ, Overdrive etc. I like to connect an echo unit here!
Third power switch. If you are using the line in for another instrument through the Leslie and don't want the generator running, this switch just turns on the preamp and Leslie circuits. This is particularly useful in recording studios where you might want to use the Leslie for hours at a time without the hum of the tone generator. One producer friend has a line from his mixing console running through the line in.
Spring loaded leslie switch. Upright for slow, right for fast, left (spring loaded) for momentary bursts of fast
Upper manual volume drop mod
Variable chorus mix
Adjustable perc decay time
