  • BD-2 vs BD-2w?

    I bought a used BD-2 a little over twenty odd years ago. About fifteen years ago keeley was posting the components to change (for a slightly more low-mids and bass response online), so I followed the instructions and it has regularly been on my board ever since. Usually I'm running it into a completely clean fender style amp with the gain at about 9 o'clock, and using my guitar volume control to clean it up (can get it all the way back to sparkly clean like this). Unfortunately, my BD-2 has started to die. It works OK for 5-10 minutes after powered on, and then a crackling noise appears and gets progressively louder and louder. Tried checking the input/output jacks, and turning the pots back and forth to clean them. I've also popped the back off it and done some simple circuit testing/debugging but can't figure out exactly what is causing the problem so figure it's time for a new one.


    I've been reading that the newer BD-2s have gone to all surface mounted components on a tinier circuit board, so I wouldn't be able to do the mod I previously did. Is the BD-2w pretty much a BD-2 with a switch for a little bit more low end? Because that sounds like what I want. Anyone with experience using both BD-2 and BD-2w have any comments/suggestions?

    I dunno about the circuits. Sorry.

    Couldn't you find an old used one?

    These said, I think the regular BD-2 sounds better.

      There is a reference for how to tell the difference between the SMT and through hole versions. IIRC, the power jack changed prior to the switchover, so you can definitively tell if a BD-2 is SMT but not the opposite.

      My understanding is the standard mode should match the standard BD-2 and the custom mode is generally inspired by the Keeley, Analogman, etc. mods. If you like the one you have, I’d try to find a through hole and do the same mod. (Or just crazy with your SMT mods.. )
      Oh no.....


      Oh Yeah!

        I've read that before, but the power jack thing is a lie. The jack on my BD-2 is the newer style one, but it's all through hole on a big board inside.

        Ugh. it's very frustrating to solder SMT stuff. At least for me.

          I may have stated it the opposite, what I mean is if you can find the old power jack, it’s definitely through hole.

          I’ll tell you who’s never going to attempt SMT mods... haha My standard soldering is barely good enough.
          Oh no.....


          Oh Yeah!

            Yours seems to work then after five to ten minutes it fades and dies

            Replace the Jack's

            My Laney GC80A amp had the exact same problem
            And it was an effect loop jack that was failing

            Heats up and opens up

            Reflow the solder on the connections first

              Sorry for the hijack but my I have a similar problem with my SD 84-40 the I recapped it and fix some "mods" the previous owner did according to the schematic. The power section works great as i can plug into the effects return and it works fine, but when i plug into the input it starts out fine then slowly fades and gets sputtery. I think i remember the jack being a little messed up looking when i had it apart but didnt think the jack would be the issue im having.

                  Re: BD-2 vs BD-2w?

                  OP: how about picking up Keeley's version of the BD-2, the Phat Mod?
                  Either that or get yours repaired.

                    I was debating that phat mod pedal (seems to sound a lot like the BD-2w C mode), but it's true bypass and I really like having the buffered bypass my BD-2 brings.

                    Currently have my BD-2 open and under my big magnifying glass on my desk. The jacks are fine, and there are no cold solder joints I can see. Under magnification though, I'm seeing something that looks like little metal hairs that seem to be bridging some connections that shouldn't be bridged on the circuit board. Not sure what's up with that. I'm going to carefully scrape them away and see if that fixes my issue.

                      Don't forget about the JB-2. It has a tweaked BD-2 and Angry Charlie together.

                        I was thinking about your issue, if nothing is bridged, do you think it could be a cap going bad?
                        Oh no.....

                          I am tentatively hoping saying that the little metal hairs were the problem. After scraping them away I didn't hear the weird noise when using the pedal last night. It's weird, like they were growing out of the solder joints.

                            Solder whiskers?

                            I had forgotten that was a phenomenon. Glad it seems to be working!
