Lectric FX – Bloozehound (Boss BD-2)

[Bio77]

Finished this one up, this weekend.  Deciding to move the power jack to the top turned out to be a big pain, lots of shoehorning required for that small adjustment.  I should have moved the instrument jacks lower. I also misjudged the height clearance requirement for Bean's new LED trimmer PCB.  I had to wire the trimmer in from the side.

For the graphics I was shooting for a late 80s skateboard look.  I really like the way it came out.  Enclosure is a polished 1590B with no film waterslide.




Here's a dual 250KB that I converted to a dual 250KA, for the build.  Only burnt myself twice to do it!

Another awesome graphic!  I really like the colors you used against the sanded enclosure, that dusty pink is great.
Super tight wiring and soldering that dual POT- I didn't know a B could be used to make an A taper- I'll surely be looking into that, thanks a lot for sharing!

Gnarly look there! I think you nailed that skater punk vibe.That's a real sneaky way to attach the resistors to the pot.

I'm really admiring your soldering lately.  Guts look fantastic as usual.

^How cool! thanks a lot Steve- you just saved me a substantial amount of goo-gaggling

That looks fantastic. Interesting contrast in the sound of the drive vs the looks. I dig it.

You won me over at '80s skateboard look! My first deck (circa 1987) was a Vision Mark Gonzales.  Now I feel like hunting down that graphic to pirate for a build.

Thanks guys, much appreciated!

Thanks for posting the link, that is the one I used    About the soldering, part of the process I picked up on from my first smd build was cleaning the board with acetone.  You need to clean off the flux to see if the smd parts are on there right.  I'm adding that step to all builds now, because it does make the guts look nice.  Trick I learned on youtube is to lay a chem-wipe over the board then use a q-tip over that.  The chem-wipe soaks up the flux and it doesn't take long.

Thanks, I had a lot of fun with this.  My dad had a skateboard shop for a while in the late 80s.  Unfortunately, it didn't do well.  However, he saved one of the decks, so, at some point I'll get an NOS Sims Staab mini

I've probably glanced at the secret life of pots half a dozen times but never picked up the linear to log coversion. So did I understand correctly that you just use a value between 1/4 and 1/5 of the overall value to achieve the taper? Looks like you used 51k.

Fab! And the look is just cool! Nice pot hack there too!

That's correct.  Tricky part is figuring out which side is the hot side.  This is my first time using this method, I'm not sure the resistor is always going to be between legs 1 and 2.

Thanks Cooder!

Getting around to building one of these. I did more reading and research on the pot trick as it didn't seem to make sense to me and found that the trick works on voltage dividers but not variable resistor setups.

"However, there is no way to get a simulation of a log taper pot in the two terminal connection. For that we have to buy real audio taper pots."

In your pic, it looks like you have the resistor between the two legs tied together, so it isn't doing anything and if you are able to get the gain settings you want than no bother. The taper, if I understand correctly, of the audio pot would allow more fine tuning in low gain selections.
