  • Overdriving a C-2?

    I have a C-2 and a Leslie 50C converted to run with it. The C-2 has a Trek percussion unit installed and a Trek reverb on the way. With the C-2 having the earlier pre-amp as opposed to theA)-28 in the 3 series, I can't get this thing to crack at all, not even tiny bit. I am thinkiong of installing a Trek effects loop and trying something like an Ibanez Tube screamer guitar pedal just to fatten it up a little, not looking for distortion just that fat tube slight overdrive. Anybody think this is a good idea orstupid idea???? anybody ever tried it?

    I've read on here that it is the Leslie amp that overdrives, not the pre amp in the organ. Have you gone through thepre amp drive leveladjustment process on Hammondwki site?</P>

      No, a C-2 has an AO-10 preamp not an AO-28 or AO-29 so I don't see any way to adjust gain on it like you would on a B-3. Theonly adjustment I see on the Leslie is a volume control that controls overallvolume not drive. I wonder how big of a deal it would be to retrofit an AO-28 in it??

        Not that I advocate distortion or overdriving amps, the C-2 has the same adjustment found in a C-3/B-3 that people adjust to get more gain. This adjustment is found under a cap in the volume control doghouse. The normal setting is 1 1/2 CCW from all the way in. By turning it more CCW, you get more volume from the preamp.</p>

        Understand that in recordings you typically hear where Leslies are overdriven, they are played very loud in the studio or live on stage. It's not like a guitar amp that has a drive control. </p>

        Also, this control is NOT a volume control. It's a feedback control set at the factory for a specified volume. Feedback gives the preamp stability. By turning the control CCW, you reduce this feedback and as such, introduce less stability.</p>

        I would recommend a preamp rebuild. You likely have a number of components that are weak and out of tolerance.</p>

          Look up Kon's Zener overdrive circuit in the Hammond Wiki.</P>


          Kon sent me a youtube demo of Pat Gagne trialingthe manufacturedversion:</P>

          If that's what you're looking for, it's supposed to be relatively easy to make. Kon's also got a 12AX7 tube EQ and overdrive circuit on the wiki, if you're curious.</P>


          I'm going to have to try the zener job on our C3...</P>
