EH USA reissue Small Stone volume drop

[Gila_Crisis]

hi, i have the usa reissue small stone that i like a lot.
the onlything that maybe i would improve (but i still can live with it) is the slight volume drop when the unit is on.

any suggestion to solve it???

thanks a lot

seen a lot in the archives
by using the S-button.

look also in the small stone project page at ggg

  Stick a little Jfet booster [or booster] with volume knob on the output/inside the Bypass switch, that way you can have _/+ unity volume when switching to SS Phasing.
  I used the Stratoblaster, board trimpot for gain, but with a regular volume knob.

This looks like a good place to show you my most recent project: a re-housed Small Stone with Univibe mods and battery drawer.



To Gila_Crisis: You don't have to do all of this to deal with the volume drop...that's just changing one resistor. I rebuilt the thing in part because I needed a sturdy and secure "test bed" for CA3094 chips. Since I was gonna do that anyway...

I did not do anything technically new here, but I figured that the mechanical design might be useful to someone else. The enclosure is Sovtek's 1790NS. If you look at it at actual size, you'll be able to see that I installed a narrow L-shaped piece of perfboard at the top left on which I mounted the phase-shifting caps. The SPDT switches are Miyama MS-550A.

One other special note: I have found in doing this kind of job that many commercial boards don't always have a convenient space between traces to drill a hole for a mounting stud. Or if they do, sometimes a large stud can't be used without danger of shorting or cutting a trace. I solved this by using a couple of small diameter studs, Keystone #1891, at two points, and making a bracket from a scrap of Lucite to support one edge. I don't carry that spacer yet, but I will have stock in a few days.

I won't do a complete "How-To" right now, but the pic will remain available. As others have noted, the 'Vibe mods do make this already useful pedal even more versatile and interesting.
