    New Build - Coda Effects Black Hole

    I've built one two years ago...sounds really nice!

    JHS Double Barrel clone sounds like dying fuzz at times

    Yeah, this thing is driving me nuts :D Will try to check the BB section over the weekend, but I am pretty sure I haven't touched or replaced anything on the BB side...

    JHS Double Barrel clone sounds like dying fuzz at times

    I replaced the diode and the two resistors, it now shows 4.2V again. I replaced the IC and re-soldered EVERYTHING...don't know what helped, but it is working now!!!! At least the TS side! Thanks a lot, man. Somehow I get a real loud beeping sound when I turn on the BB side now :D

    JHS Double Barrel clone sounds like dying fuzz at times

    Could it be that IC2 got too much voltage due to the lately measured 8.6V? On the other hand, the sound was the same before the change...

    JHS Double Barrel clone sounds like dying fuzz at times

    I just built myself a simple probe and checked some of the flow... The sound is clear until I reach the TL074...not sure if it's supposed to be like this, but on pins 5 & 10 I hear the clean/clear sound, on the pins 6/7/8/9 it's already fuzzy...obviously, everything after these parts in the...

    JHS Double Barrel clone sounds like dying fuzz at times

    Hmm, one of the probes is touching ground (from the DC jack) and the other one leg of the particular component...

    JHS Double Barrel clone sounds like dying fuzz at times

    What do you mean? by the way, would it help to decrease the values of R32/33/34/35 to 10k?

    JHS Double Barrel clone sounds like dying fuzz at times

    First of all: Thanks for the time you're taking to help me! I really appreciate it! Thanks! I don't think so; I even changed them both... You had me for a second....but I checked thrice, I'm 100% sure I measured DC. Unfortunately, I don't have a probe... Nothing changes.... 8.34 & 5.99...

    JHS Double Barrel clone sounds like dying fuzz at times

    Replaced C26 and it's still acting the same way. Even before reaching C26, the voltage of R32/33 drop when I play...

    JHS Double Barrel clone sounds like dying fuzz at times

    R12 shows 4.04 & 2.66 without playing; 2.39 &1.57 when playing will try replacing/removing C26

    JHS Double Barrel clone sounds like dying fuzz at times

    Yeah, I tried several transistors. All with the same result. I swapped C1 now, but all caps show 0V on one side and 1.07V on the other. What I noticed: R1&2 show 0V on both sides. Because basically all components on the TS side showed the same voltage decrease, i then started to measure the...

    JHS Double Barrel clone sounds like dying fuzz at times

    Sorry, I don’t have much of a clue...which ones would that be?

    JHS Double Barrel clone sounds like dying fuzz at times

    Tried several power supplies (Cioks DC7 and DC10 and Strymon Plug). All with the same results. How do I do that to get reliable results? Would you check only the TS side of the pcb? Or both sides? Check the voltages of all components?

    JHS Double Barrel clone sounds like dying fuzz at times

    I just checked. When I don’t play at all or play slow and calm, the emitter of Q1 shows ~3.33 V. The fast and louder I play, the sound gets fuzzy and the value Q1 if Q1 decreases to under 2V, lowest was 1.76V and really fuzzy sound...when I don’t pick anymore, the value slowly increases to 3.33V...

    JHS Double Barrel clone sounds like dying fuzz at times

    I wrote the guy at effectslayouts who only responded: „I have not run into that with my build. Maybe adjust R4, which is biasing the gain/clipping stage.“ do you think this could be a Solution? further, I measured the following values on the TL074: Pin 3: 4.01V Pin 5: 1.07V Pin 10: 1.07V Pin...

    Hi Barry, here’s the other side:

    Only this side for the moment. Will try to unscrew everything and make pics of the other side tomorrow

    JHS Double Barrel clone sounds like dying fuzz at times

    Thanks for your reply. no, I haven’t. Actually, I wouldn’t know how to properly do it... I just checked the ICs, they seem to have good values at 4.44-4.58V. The Emitters of the transistors show 3.53 (Q1) and 0.36 (Q2). Could it be the R3 at 10M is a reason? The normal TS/Moonshine schematics...

    JHS Double Barrel clone sounds like dying fuzz at times

    I just finished a JHS Double Barrel clone yesterday and it sounds great. It’s desinged by effectslayouts.com One thing I’ve noticed though: the TS side sometimes sounds like a fuzz with a dying battery or gated fuzz. When I disengage the TS side and turn it in again, it sounds normal. Here’s...
