  • M3 effect loop

    Hi,

    I am still trying to find a good solution for installing an effects loop into my Hammond M3. It is connected to a Leslie 122 via a 8010-Kit. Before
    I got the Leslie, I used a self-built line out like this ( http://www.dairiki.org/HammondWiki/LineOutFromASpinet ).

    My question: Would it be possible to install that line out again before the 8010-Kit , send the signal to an effects unit, and then send it back into the
    signal which goes to the 8010-Kit?

    Greetings
    Christian

    Yes, but you would need to add an extra amplifier stage after the effects to push the signal back up to proper "Leslie level".
    Current organs: AV, BC, A-100
    Current Leslies: 22H, 142, 147, 760
    Organs in the past: L-100 (several), M-100 (x2), T-100, E-100, CV
    Other keyboards: Roland FP-4, Yamaha DX7, Yamaha TX81Z, Yamaha Motif ES Rack, Korg Krome, Novation Mininova

      The line out would work on the input side however as enor stated you will need to bump the output back up AND generate a balanced output.

          There is more than enough gain to drive a Leslie 122 balanced from a mixer.
          At this point,send whatever you like to the 122!
          Add whatever FX you need.

          A small mixer is a great investment,play with phones on and practice away.
          Mix in your MP3's you have to 'accompany' and your 'minus' midi tracks you jam to.
          AND....add FX to your AO29!

          Speaker DI's vary in cost and quality.I use a red Radial!

              No, not if you wish to keep using the Leslie kit. The secondary side of the transformer does send a balanced signal to the Leslie, but will have DC speed switching voltage. Avoid connecting external gear to that line at all costs.

              The signal feeding the primary side of the transformer inside the 8010 kit is single-ended (unbalanced.)

              Whatever you do, keep 2 things in mind:
              -- Make sure the AO-29 amp always has a sufficient load across it.
              -- Don't tamper with the balanced signal that is directly connected to pins 1 and 6 of the Leslie, or tamper with those particular signal paths inside the Leslie kit. DC voltage (80V or so) is going to be present there when speed switch is set to chorale.

                Hmm....that effetcs loop from Trek costs 138$ for one manual....plus shipping costs to germany
                Maybe I just keep it as it is and just add reverb in the mixer.

                  I found an fx loop kit for tube amps at

                  https://www.tube-town.net/ttstore/Ba...112::5992.html

                  Would you think this could be inserted into an AO29 like the organ mate? Will it work?

                    You can create a Series FX Loop on the AO29 amplifier by splicing into C21 which is off of V4 in the amp.Click image for larger version

                      has anyone tested this?
