    Bathtub Reverb - Issues

    Or you get some red LED's from that Tayda batch that are all backwards....

    Noisy Power Supply Question

    IMO anything from 220-470uf is fine. I have done pre/de-emphasis on EQ's, but typically wouldn't on most other pedals - even then I removed the pre/de circuit and found it made such a tiny difference I could have entirely omitted it and probably never heard a difference. I have never found a...

    Noisy Power Supply Question

    I live at the base of a radio tower, so I've always had issues with noise. Originally I thought it was just a noisy power supply, but after moving things around my house/trying different properties, playing with faraday cages, etc I found something super weird - I had RF noise from the power...

    Pondhopper?

    Been trying to see when this bad boy is gonna be in stock. Sent off a couple of messages to find an ETA and gotten no reply. Anybody know roughly when they're going to available? Postage to Australia sucks so trying to get a couple of boards together. Cheers!

    God I hate how pads look in the new PCB editor :oops:

    Increasing B+ on Bassdude

    Based on other peoples testing and what I've done, there's a couple of easy mods to squeeze some extra chooch out of it: *change to higher current inductor (as they're already on the border of being saturated) *change to a lower Rds MOSFET which allows more current (I use a IRFB17N50) *modify...

    King Nothing High Frequency Noise

    I've tried three different power supplies - everything from isolated switchmodes capable of 12v/1A, to unregulated 12v plug packs. No change whatsoever.

    Discovered my red clear led are reversed

    Yep. I got dozens of them, and only figured out when the classes I was teaching had working pedals but no LED. It's very annoying :ROFLMAO:

    King Nothing High Frequency Noise

    Did you ever get this sorted? Mine also has horrific noise, but it doesn't go away

    King Nothing - Oscillating

    Ok, tried a few things: Decreased R5 (plate resistor on second stage) from 220k to 100k. No change Tried an old EHX 12AX7B I had spare from my amp. No change. Tested a 100pf cap in parallel with R13/R14 for RF suppression coming in, as well as across D/G of the J201 (in case it's oscillating...

    King Nothing - Oscillating

    Howdy, Built a King Nothing. Everything works fine, voltages are spot on (254v on the plate resistors, and 29v heading into the J201), but there's significant amounts of oscillation that decreases as the gain is turned up. Low switch has no impact on the noise, but the left position of the mode...

    Planning on building a Skeptical Boost?

    Complete isolation between the pre-regulated power and signal circuits, allowing any power supply to be used.

    Tear Jerker Wah

    Rust-Oleum Matte Black printer + Dulux Marble Effects Gold. Couldn't have been easier if I tried. Pretty happy with the timber, and confident I can get the other build I'm working on done as I imagine it (if enclosures ever turn up from Tayda)

    Tear Jerker Wah

    Got the base cut finally - very happy with how it turned out!

    Suboctave Pedals

    All great suggestions! I do have a couple of wah enclosures, and I'm pretty sure I've got all those components for the Pompei in spares.... And just for the laughs, this is the artist in question. Yes, that is a full size pedalboard attached to his bass.

    Suboctave Pedals

    I've built an 8 Bitar from them, and not super impressed with the PCB or documentation really. It could also be influenced by the fact it took 14 weeks to show up. Would rather stick with PedalPCB or similar companies

    Suboctave Pedals

    Howdy, Doing some fundraiser builds for somebody in my extended friends circle dealing with cancer, and the artist doing all the artwork for the builds really enjoys glitchy/super wild sounds (he owns a bass with a pedalboard literally built into it). I suggested we go for a suboctave build...

    Schottky BAT47: equivalent?

    47's have been obselete for a while, but almost any schottky will work in this position. 1N5817 1N5818 1N5819 1N6263 (15mA max continuous) 1N5820 1N5821 1N5822 BAT41 BAT46 Etc

    Tear Jerker Wah

    Had a couple of wah enclosures sitting around that I've been slowly rebuilding for a while. Had a couple of days off over Xmas and finally decided what I wanted to do with one, and I think it turned out pretty well. This was a test to see how laser cut bamboo would work for pedal enclosures...
