  • Difference between PD125 and the old PD120?

    I saw a couple of PD120 on ebay. Could someone tell me how they are different to the current models?

    Thanks

    The difference is how the triggering system is mounted. On the PD-125, Roland use a 'Spider Basket' design, with 1 centrally mounted piezo for the head, and another below it for the rim. The PD-120 has a cross-bar for the head piezo and a few piezos mounted directly to the shell. The difference is, theoretically, that the rim response is more even on the PD-125.

      Actually, the PD-120 uses a single piezo for the rim. It is mounted on the edge of the crossbar. I have both PD-125s and PD-120s on my kit and the rim triggering for the PD-125 is clearly superior. The head triggers seem about the same to me.

      But, with some tweaking you can usually setup the PD-120s fine. I wouldn't hesitate to use them as toms. I prefer the 125s for snare, but could manage with a 120.

        I am looking to upgrade to the PD -120 or 125 for my snare. I have a TD-8 brain with all Hart Dynamics pads and Roland cymbals . I am currently using a Hart Dynamics 13" pad for my snare (these are older pads and are not double trigger). I just took the mesh head off and I noticed that the green foam column in the center of the drum had broken off - So I put a 10" Hart pad in its place and WOW!! What a difference! I guess the foam needs to be replaced (can it?)

          Thanks Michael, not having one to examine makes my answers a little less accurate than desirable sometimes!

          John, yes, you may need to replace trigger cones occastionally, how long have you had the pad? Its a case of 'sawing' off the old one and sticking a replacement on. There are threads around here somewhere with a detailed procedure.

            ige87 - Thanks for the info - although I didn't purchase these new (they came with the kit I bought used) I think they are around 6-8 years old? I'll saerch the forum for the thread on replacing the cones.

            Thanks,
            John

                Just out curiousty (or complete stupidity)...besides size, is there much of a difference between pd85 pads and pd105's or pd125's??? I have a TD-20 module, but use pd-85 pads. I leave the trigger settings as pd125's and it actually gives me a louder sound then if I set the triggers as pd85's.... but in how they are built...is there much diff? Thanks

                  John:

                  Replace the foam and you'll discover you don't need to "upgrade" your Harts.

                    The basic technology is the same. Instead of having a basket, the PD-85 IS a basket. All three use a piezo/cone for the head and a center mount piezo for the rim.

                      is it worth tweaking the 120's for toms with aTD-12 , if so what are the tweaks.
