    SOLVED Dielectric boost - no change when boost channel is engaged

    These connections look a bit suspect to me, especially the one on the right. There's some like that on your switch board too. @Feral Feline's advice is solid. Wait for your new soldering iron, it should give you better control of the heat.

    Gloryhole: Is this it?

    Hmm, doesn't sound quite right. It's not a high gain pedal, but it sounds like you're only getting clean boost. You should be getting clipping overdrive with the gain up.

    Getting a free radio with your pedal should be seen as a bonus.

    j113 and 2n5458 from tayda?

    I was pleasantly surprised that the 2n5458 I got from them was perfectly in spec. Sample size of 1 though, so can't vouch for all of them.

    Distortion 250 schematic noob questions

    Change C1 to 1.5N put a 15pf piggyback on R2 (I doubt this changes anything though) R3 to 5.6K (this won't really change sound) C5 to 1.5N use germanium diodes for D1/D2 use C500K for gain pot and A10K for level (you could use A100K for level just fine too) There's no pull down on the PPCB board.

    Distortion 250 schematic noob questions

    Let's narrow the question down, which version of specs from the EL doc are you wishing to build?

    Question about blend pot VS switch

    Take a look at the Dingo schematic. It has a pot to blend clipping.

    SOLVED Greer Black Mountain Drive troubleshooting assistance

    looks like a solder bridge at the top right of the photo, but that could just be the angle you didn't say what's wrong. no sound? some sound but low? whining noise?

    Can anyone recommend a tube screamer

    I think the Landgraff mods are the one's mentioned here ggg_its8_mods.pdf (generalguitargadgets.com) under the section "Expensive Boutique Modifications"

    Crunch Captain to Angry Andy

    The 2nd gain stage of the CC has a fixed gain (all the gain adjustment is made in the first stage). On the deluxe, the Mode basically toggles the gain of the 2nd stage between 3 different settings.

    SOLVED ONLY works with cable plugged into input jack.

    Are you getting a good ground? Check that the inside of the enclosure has continuity with the negative power lug, as well as the ground on the jacks.

    Crunch Captain to Angry Andy

    It has two gain stages, using both halves of a dual-op amp chip, followed by hard clipping diodes. To explain the circuit, refer to this article about the Guvnor: ElectroSmash - Marshall The Guvnor Analysis. Everything there applies since they are all Guvnor-based (CC has a simpler tone stack...

    Is this a trick question? The AA doesn't have any component changes compared to the CC, other than an added clipping diodes option.

    Can anyone recommend a tube screamer

    I've always liked the Touch (PPCB Contact). Simple, no frills, 3-knob, slightly tweaked TS. I think I like it because of the LED clipping, which is also the setting I tend to like on other TS's I've played.
