2 effects in one box

[nero1985]

Hi guys, been a really long time since i was on the forum,

I'm about to start building 2 pedals that I want, a BSIAB 2 and a BYOC delay, i wanna put them in the same box, i want the BSIAB to have two master volumes that i will switch between (one for rhythm one for lead) and i want that delay only on when i switch to master volume 2, i already know how to get all these things done and i was thinking about just adding an effects loop on the BSIAB pedal but then i was like "maybe i'll just build both in the same box and i will use my current delay for additional sounds"

that being said, i just need to know if since the BYOC delay accepts 18v if by building them in the same box i could use the same DC input and use 18v to power both without any issues, i can always just use 2 separate DC inputs one for each in the same box but im just curious to see if i can do this, thanks!

Looks like you have 2 options.  One is to run them both on 18V.  Of course, all your parts gotta be rated over that.  It might also change the BSIAB, giving more headroom and making it cleaner!  But maybe you can get past that by biasing.

The other thing I see is to input 18V for the BYOC, and then regulate down to 9V for the BSIAB.  No big deal, just a regulator and like 2 caps...it's what I would probably do, FWIW.

Hey Mike!  I guess I'm stalking you... =D  Get off this board and go get hitched!!!

To the OP - using a charge pump to get 18v?  The delay will suck a lot of current, and charge pumps can only supply so much current at 18v.  The BSIAB is probably minimal current draw, but keep it in mind, especially with LEDs etc.  Use your DMM to figure out how much current the delay is drawing at maximum and minimum delay times.

Mike - I know you're not yet a BSIAB experimenter.  FYI at 18v, the BSIAB gain stages aren't cleaner....they're dirtier, but it also changes fidelity and the 'shape' of the waveform. Anyhow, higher voltage allows the mu-amps to produce more 'gain' which means the first stage hits the second stage harder (All else being equal)...and as a result, is 'more dirtier.'      Things actually get cleaner when you lower voltage up toward about 6v (after which, the ones I use just don't function, but I think J201s will go even lower).   Otherwise, It ain't easy to get the BSIAB clean unless you mod it and or drastically reduce gain at the input (turn down that guitar volume).  Depending on your mods...even then it's just lower gain...

If you use a BYOC delay board, you can probably use a DC jack that splits to each pedal.  9v from the DC jack can go to the BYOC board, which then does all sorts of stuff with the voltage for that board (regulates it, charge pumps it, as needed).  Then, right off the DC jack 9v you can also wire the BSIAB board, so it sees 9v, unaffected by the BYOC board voltages etc.   I wouldn't use a stock BSIAB beyond 9v, it's already overkill to me.
