I love my current Hammond/Leslie set-up, but I understand there is a way in which the main Leslie amp can be modified to accept 1/4" jack plugs for use with effects pedals (specifically, for my interest, an overdrive unit and - don't laugh - a wah-wah pedal).
Has anyone any idea of how to do this? -------------

are you handy with a soldering iron, JG? Since the 145 has a built-in amp, all you really need to do is connect the two input-jack wires (black and red) to the ring and tip of a 1/4" jack socket.
The levels might not be quite right to make the most of pedal effects, though...you may still need some kind of preamp (but a good overdrive, placed before the wah, might just give the signal enough boost). If you have the cash, it might be a better (or safer, depending on your skills) option to buy one of the dedicated "combo preamps" such as this one: http://www.btproductions.com/Gear/Preamps/Hampton/hampton%20preamp.html - http://www.btproductions.com/Gear/Preamps/Hampton/hampton%20 preamp.html ------------- http://www.last.fm/user/sollipsist/?chartstyle=kaonashi">

No, but I know a man who is 
Many thanks, James - I'll get the beastie growling, if it's the last thing I do. -------------

^ Ah, so the truth comes out! Many thanks, VG, for the first honest laugh this forum has given me recently. If she's anything like my wife, it was the phrase "if you have the cash" from my post that really inspired her to comment. (tell me, Jim, do you ever slip up in the heat of passion and call your wife "Leslie"?) ------------- http://www.last.fm/user/sollipsist/?chartstyle=kaonashi">

I probably don't need to say this, but if you adapt the input of the Leslie you'll have to put a corresponding 1/4" jack or plug on the organ output as well (so that you can actually plug it into the effects). ...make sure the other wires still connect directly (constructing two seperate cables is probably the best way to go) because you'll still need the power supply & coil relay. And whatever you do, test the connections BEFORE you plug it in...sending electric power into the audio path would be, uh, very bad. ------------- http://www.last.fm/user/sollipsist/?chartstyle=kaonashi">

I believe there is already a 1/4" jack output on the Hammond if I remember rightly. It was only me convincing Jim that the dining room table would fit in the kitchen & a Hammond would be a much nicer piece of furniture in the first place that meant e-bay was "consulted" !! ------------- Confusion will be my epitaph |

Hmm, you're absolutely right...the Hammond has a direct 1/4" output as well as a dedicated Leslie connection. If you really wanted to give yourself as much flexibility as possible, you could put a potentiometer in between the two audio lines and then have the option of mixing the straight Hammond output and the effects line (for one thing, you wouldn't have to reconnect the proper cables when you wanted to switch back and forth). You're getting me all excited about this project. I may have to go out and find a little 'furniture' myself. ------------- http://www.last.fm/user/sollipsist/?chartstyle=kaonashi">
