I built the magnetron and there is no audio at all upon firing it up. The rate led works in conjunction with the controls. All the voltages in the ic chips were good. I swapped chips to check for bad ones, no dice. So I decided to use an audio probe. Pin 1 of R2 had a modulated signal but pin...

The Buff n Blend is what I use to put all my circuits in parallel. This was a my first parallel build that I had sitting around forever that I never bothered to put a wrapper on. The board has a pinout for a 100k pot for clean blend. Instead I used a 47k resistor to keep it at the midpoint and...

Double Guitar PCB D'lays that is. Don't persecute me but I took the photo before realizing I forgot to hook the wires to the power jack. Also a quick video of the pedal in action. Both pedals are in parallel so varying the rates produces an excellent texture effect like the Hydra. The benefit...

Thank you for your reply! The volume is low throughout. I do have a sole 12k resistor there, I ran out of 15k's.I played around with the values there 10k to 18k and did not produce any discernible effect different from how it currently functions.

I have a dual hydra build going. One works just fine (I damaged a trace on the feedback pad of lug 2 and had to jumper it to the fv1 chip). The other one is throwing me for a loop. It is very low volume. Increasing the value of the volume pot from b100k to b500k does increase the level to unity...

Definitely building this!

Here's a hack job of a demo. I had issues mastering and could not nail down the timing for the life of me.

EMG 89.

I'll try to have a demo soon; having trouble mixing what I recorded because of clipping! Hopefully it will do. I can always send this to @jjjimi84 if he wants to shill. :LOL:

Done!

Thanks again to you and @giovanni ! I feel bad for not thinking of the obvious answers first! No need for FOMO on piezo. There are a lot of ways to skin a cat and since you build pedals, you have a headstart.

The 18 volt works. I might change to Giovanni's solution. The gpcb tone tweq I have in there has a 10v 47uf cap. Unless I change that.

I was hoping to connect two in parallel but I suppose doing it in series solves my problem too!

I am building an electronic acoustic that uses a L.R. Baggs preamp with a piezo and a active pickup. I will be using two 9V batteries to power the thing. Where I stopped in my tracks is where to connect the negative terminal of the second battery powering the pickup. The preamp has positive...

It looks better than it sounds.

Fun discovery, you can put an effect into a feedback loop! I am not sure if all effects work but the chalumeau does. This build features a unison double tracker into a Leprechaun. Then there's the feedback loop. It can do the lush chorus thing and some pretty unpleasant stuff. Like a cat...

Wish it was as easy as wiggling my nose!

It does track well all things considered. The lag control produces the delay in the signal. With it fully CCW, there's not much delay and it does track on multiple strings satisfactorily.

Only at the cost of sleep. Also, I have no kids! It was a six string feeding the effect btw!

Another three in one. This time it uses two organ donors in parallel capped off by an arachnid with various patches from MAS- Effects. The draw of using the two organ donors is the lag control. Putting the controls on either pedals at opposite ends makes for a cool arpeggio effect! I threw in a...
