Re: Guitar Cable Tester

Talent wire from parts express. ... Wierd thing , it was measuring 62k between conductor and shield. ... So I cut off both ends, resoldered, 1 ft less than before, still getting leakage resistance on cable. Running my hand and squeezing the cable made the resistance change but would not open or sho...

Re: Lehle Sunday Driver [schematic] [schematic]

...the power-supply is a bit strange, it's not the best idea to power a 9v linear regulator with 7,5V imho... Your schematic says "all voltaged measured with 9Vdc power supply." It looks like it requires AC power. With AC power you would have higher than 7,5V at the regulator input. of co...

Re: Lehle Sunday Driver [schematic] [schematic]

thanks! r4 is 47k, voltage of 0,125V is measured. someone posted the schematic of Lehles paralell pedal here, the small bias-offset is similar.

Lehle - Sunday Driver [schematic]

hello my friends, long time no see, i hope everyone is still alive and doing great? :D i just spent some minutes tracing the lehle sunday driver, a great sounding buffer / booster which i use in the studio all the time to track guitar di's (instead of the interface/preamp hi-z in). nothing too speci...

i traced the older 3-knob-version. "vioce" is just a variable resistor for R5 (lok at the zendrive) about the other "mosferaut"-schematic, i asked alfonso some years agoo about it. his answer: > That design has nothing to do with my commercial product. I just liked the > name so ...

Re: Okko - Diablo Boost+ (goop pics!!) [traced]

looks like heiko (mr. okko) changed some things in the newer pedals. From his FAQ: "Does the Diablo Gain+ have more gain than the "standard" Diablo? No. Activating the "+" mode has the same effect as turning up the gain control. If the gain control is already on maximum, the...

hey kusi, i appreciate it! that's what ryanuk posted a gutshot of, but on the gutshot you see there are only 2 internal trimpots (instead of 6 on the schematic), did you just include that for more tonal options or does the original indeed have 6 trimpots which we cannot see? maybe under the goop? :...

Re: Okko - Diablo Boost+ (goop pics!!) [traced]

i traced the "+"-version with additional booster ("more"-circuit).
for the normal-version, just build the "rock"-circuit.
