  • D152 pedalboard question

    I just acquired a D152. It plays beautifully. A slight hum. I expect to be filter capacitors in the power section. But otherwise plays beautiful. It does not have the stock 32 pedal foot bass pedals. It came with a 25 pedal. Which functions but does not seat properly. I was wondering how hard it would be to get a hold of 32 pedal for it? I’m in northern ca. Far north. So not a lot of options here. Thanks in advance for any knowledge here.

    Wow. The 32 note and 25 note pedal boards are so vastly different that I cannot fathom what modifications were done to a D100 to allow a 25 note pedalboard to even function.
    Pictures would be nice just to see what all was done.

    As far as getting a 32 note board, I would say that chances are slim...I can honestly say that I have never seen just the pedals for sale anywhere around here or on Ebay. These things weigh a LOT and are huge, so shipping would be a challenge.

    Then is the possibility that someone made modifications to the mount on your D100 and there are now parts missing that are needed to mount the larger board.

    Pedals from any RT or E will work...again assuming no modifications were made to your D100.

    I further assume that the bench you have is the larger one, made for the 32 note board.

      The metal tabs make contact. So it plays. But pedalboard can move left or right an octave Very strange. Will get pics.

        The difference is that the 32 note board is curved, the 25 is flat.
        There is a couple inch difference from the base of boards to the point where the pusher hits the pedal contact switch, the 32 note is much taller.

        This is a Concert E which uses the same pedals as the D100

        This is any 25 note pedal board mount.

ID:	605978 The brown bar is the downstop; the felt cushion is nailed to the bottom of each pedal. The distance from downstop to switch contact is the same for every note.

        I am really curious how this was put together.

            OP said it "came with" a 25 note pedalboard....not necessarily that it was retrofitted for one. He also mentions it works but does not seat properly. Square peg/round hole!

              Having a hard time uploading pics from my phone. But will soon. As Joey said square peg round hole..it sort of fits but is not practical or reliable. Also, I am doing some troubleshooting. It seems to have some intermittent issues. Sometimes very faint output and a lot of rumbling like thunder. I assume its tubes. As I am a guitar amp guy it sounds a lot like when preamp tubes die in a guitar amp. Any Ideas of what else it coould be? Also had some squealing (like feedback) seemed to be related to the reverv tank. Thanks in advance.

                  Well - looks like it's a good brain workout playing that thing, having the pedalboard transposed vis-a-vis the manuals like that :D

                        I found the intermittent problem. Microphonic bad 12ax7. Replaced. Problem solved. Now to find a suitable 32 note concave pedalboard. We think an rt3 or other will be direct replacement?

                          Yes - without question. Any RT series or Concert E pedalclavier will do.

                            Well I’ve been able to make the 25 note function more reliable with some woodblocks supporting it. Some of the tabs are making contact on switch inconsistently. I don’t think tabs need to be bent more. But. The little felt loops on switches. I’m not sure if they should catch the tab or they just cover the switch. Does anyone know about those felt loops?

                              The felt tabs are used to cushion the metal to metal contact so there isn't an audible clicking when a pedal is pressed. The spring pedal contact itself should ride just on top of the felt.
