I used 2n5088 transistors in place of the 549c. The BOM calls this out. If you are having issues with your build start a thread in the troubleshooting section with clear pictures of your board (both sides) and wiring. I will say up front that everyone here is pretty helpful, but for the sake of...
I typically drill a big enough hole to fit the larger flange, nip off the anti rotation nib, use an extra large washer to hold it, then use flush cutters to nip the extra height off of the switch shaft
Perf/proto board feels like the next step up in between PTP and actual PCB and it’s only as ugly as you make it. For me it’s easier to translate a schematic into perf than Vero but that’s just me and I may just be dumb that way. Perf also offers a little more stability over PTP
If it’s not an actual guitar pup I would guess it’s most likely a piezo under the biscuit/bridge like an under saddle acoustic pup. At which point @phi1 would be correct that you will need to pay attention to the input impedance. I have run an acoustic with k&k style pickups (still a piezo) with...
Let’s ask the question then what kind of pickup are you talking when you say “passive”, are we talking something like a contact/piezo/K&K, mic, or a standard wound guitar pickup?
Any slide style guitar without some dirt/fuzz is lacking. But if all he is looking for is more louder then just build him an LPB-1 or go super fancy and build an Equilux
Love the Ruby! Truly a fun little beginner project. Cigar boxes got expensive and scarce there for a while during the cigar box guitar/amp/purse era a few years back. Glad to see projects like these. They really don’t sound all that bad even.
I have used them in a few builds mostly for ease of potential troubleshooting but have rarely ever had to take advantage of that ability. I had to use one in the Shallow Water because of the space constraints. Frankly I just like the look of the smaller lumbergs and being able to use the power...
You can plug the intelligent relay into the R1 pads either to add or break the clean. I think lifting pin 1 of the 4027 will remove the oct2 but someone needs to put eyes on the schematic besides me
