Broadcats - Duocast

This is a very cool pedal. I managed to try it out at a jam yesterday. Lots-O-Fun. Tried it with humbuckers, single coils and P90’s and all have a setting that sounds great. I like that versatility. I even tried it on bass and it sounded especially good on the 27 volt position but did well in 9 volt with some breakup.

I did note an oddity when switching between 9 and 27 volts. If you’re actually playing and switch, it sounds as if everything discharges and then recharges and audio fades back in after having died during the switch. Is this normal? Is switching voltage never to be used mid-performance? I have no experience of switching voltage during a performance (not that I’m one to fiddle with settings during a song … but I made an exception because this was the new toy on the block).

The build was fairly easy. Drill templates were weird. I use StompBox layouts when I can to model things and make sure they fit. I looked for a Tayda drill template for the rev 3 board because you can import them. But they were all off. I know this from printing and simply placing the PCB over the print. The only one that was dead on was the template in the build doc on PedalPCB. Thankfully, they are provided as layered PDFs and I was able to use that to get the dimensions needed.

The only odd component was C9, A 330uF cap. They are rather large. I found a Wurth cap that was only 8mm diameter but it was too tall for a 1590BB2. I might have gotten away with it (if it weren’t for those meddling kids!) if I had used a 1590BBS.

The enclosure is a Tayda 1590BB2 in Winked Silver (I really like that finish and have used it several times). I used blue Neve style knobs and red and green water clear LEDs. This is also the first time I used two different waterslide decals on the same enclosure. The “Broadcats” decal is a Koala No Spray white and came out great. The footswitch decal is a Koala No Spray transparent. As you can see, the transparent is hardly transparent and I’m having regret for using it.

All-in-all, I have enjoyed the pedal so far. It was a worthwhile build considering the majority of my builds have been dirt/drive pedals.

EDIT: I moved the LEDs from the original position because they … just f’d with the aesthetic of the pedal.

I built an EP booster and I think what you describe is normal charge pump behavior. Switching from 9 to 18v on the EP while the pedal is engaged causes a pop and lag.
Only operate that switch when bypass is engaged.

Great looking pedal!

Wow - nice work! One thing you can try with oversized capacitors is to mount them underneath the board. With the Broadcast in particular I have mounted that 330µF cap under the board and also laid it on its side. There's enough length in the leads to do that. It makes fitting everything in together a lot easier.

Thank you! I’ve seen many of you discuss the tactic of placing components on the pot side of the board. It just didn’t cross my mind during the build. I also saw a post from @Robert thst a 10mm would fit there. As you can see, it just fits. Even the transformer poked about a half mm beyond the enclosure without the lid. Thankfully, there was enough clearance with the lid. As I said above, a 1590BBS would have given all the clearance needed without any concerns.

Definitely found this was necessary for my build as well.
