  • How hard is it to connect a trek II percussion to a Hammond BV

    Thinking about buying a serviced Hammond BV organ but before I did I wanted to know how hard it was to hook up a trek II percussion to the organ, since I know the organ lacks percussion. Would a noob to the hammond organ modification world be able to install it successfully lol.

    It’s very easy. If you email Mike at Trek he’ll probably send you a copy of the installation instructions. I added one to mine.

      It's not hard to install it. The only downside is that because the design of the V-series preamp is quite different from the -2 series, you get the vibrato/chorus effect applied to the Percussion signal, which is not the case in 3-series organs. This problem has been discussed on here in great depth in the past, and I don't recall that anyone has ever come up with a solution.

      For example, volume control in the V-series organs is upstream of the preamp, so you have to mix the Percussion signal with the main signal before the volume control if you want Percussion volume to track with the main audio signal.

        Percussion OR vibrato chorus available on V series.Not both at once like a -3.
        Bummer for playing jazz,even rock Black Magic Woman has both too.
        V series won't get you there.One at a time.Maybe you like chorus on your perc? Not this guy.

          FWIW, I'm working on that very issue. It's a couple months out there yet, my plate is pretty full, but my CV (and C2) and at least a couple of others *will* be getting proper percussion 8)

            The good part of it though, is that if you run another instrument through the input of the five tube amp, it also gets affected by vib/chorus. Sounds great on EP and my old Korg CX3.

              Once ran the Roland SH1000 through the M scanner.There are synth bass upper keys (25-37) on a 45 RPM I recorded with that little mod.
              The signal chain of the older models allows that input.Too bad the perc can't be mixed 'post'.Adding an 'aux' in 1955 wasn't going to happen LOL.

              Easy to accomplish on newer amps as well - just run the external gear to the preamp's vibrato input.
