    VFE Merman - Oscillation (?) motorboating at higher gain

    I just got a reply from Peter, again I'm not sure how helpful this is for the other circuit but here's what he said: "While that is certainly a unique symptom, it does sound like there is a DC bias issue. This could be caused by many things, but the most likely is an op amp that is either...

    Missing Build Docs / Schematics

    This is probably getting annoying for you, but any idea of an ETA for the Pro-10 Tayda drill template as well?

    VFE Merman - Oscillation (?) motorboating at higher gain

    You're probably right, actually.

    VFE Merman - Oscillation (?) motorboating at higher gain

    This is the system that came with the Merman PCB, although it's all SMD rather than through-hole components.

    VFE Merman - Oscillation (?) motorboating at higher gain

    The trimmer comes stock at noon, so following what he does on the video I turned it to all the way clockwise to 3:00 - no motorboating, but it sounded like shit and not much drive - then went counter-clockwise until I hit the skipping sound, then dialed it back clockwise slowly until I had a...

    VFE Merman - Oscillation (?) motorboating at higher gain

    Mine are from Tayda. However, I have an interesting update. I fixed the problem by adjusting a voltage trimmer on the SPS switching board that VFE provided with the PCB. It took a few minutes, but basically adjusting the input voltage down got rid of the issue. He goes over the whole assembly...

    Shika - Mod to Reduce Volume?

    That did it, this thing is a beast but more manageable now. Cheers.

    Shika - Mod to Reduce Volume?

    I realize this probably isn't a common request, but is there an easy mod to lower the volume on this thing? I like loud as much as the next person, but unity at 9 o clock is a little excessive for me.

    VFE Merman - Oscillation (?) motorboating at higher gain

    IT'S THE SAME EXACT THING. So Frustrating.

    VFE Merman - Oscillation (?) motorboating at higher gain

    Hi, I have a VFE Merman that I built using the actual SPS board from VFE, just boxed it last night. I'm pretty happy with it, but when I finally had a chance to really crank it today I noticed that it starts motorboating the last 20% or so. I don't really plan to use it at full gain, but still...

    SOLVED Plugging into input jack shorting LED and circuit? Mercurial Q-Boost

    I should really label my stuff better, I never would have caught this. Thank you, I have the correct ones in my stash.

    SOLVED Plugging into input jack shorting LED and circuit? Mercurial Q-Boost

    Sure thing, bottom and top here. Let me know if I need to get clearer pics, I have trouble getting macro shots with my phone lately for some reason.

    SOLVED Plugging into input jack shorting LED and circuit? Mercurial Q-Boost

    Hi All, I am having a weird issue I've never encountered before on a build. Plug in power, looks good. LED goes on and off. Same with the output into the amp. Plug my guitar input cable into the pedal and the LED lights up dimly. If I press the footswitch, it gets brighter, and the effect kinda...

    Can I use the PedalPCB 3pdt Breakout and Order Switcher for This?

    Awesome, thanks for the help! I actually ordered another handful of these off of Gerber, if you're in the US and want to PM me your mailing address I can drop one in the mail for you after I get them and make sure they look good.
