Build Your Own Clone Message Board

Once again, thanks for all, tonmann. I bide my time patiently as we get closer to the "T's". I'm waiting for the Triple Fuzz.

Me, too!

Im tempted to try this Psytar, the variation of the jawari, cuz ive got a jawari, and its okay, but it doesnt do exactly what i want it to do, mayhaps ill try this other one when i have time.


thanks for posting all this stuff man!

I don't mind jumping a few to do a request (especially for one of the easier circuits!):





Five cuts and two jumpers.

If you intend to make this a true bypass circuit and need a tie-down resistor (1MΩ) at the input, you can connect the resistor between g3 and h6 - it's not very elegant. If you want elegance, cut at h5, jumper between g3 & h3, resistor from h4 to h7.

tonmann, thanks for letting the Tripple Fuzz cut the line! ^^^^^^^^^

Something to give to the bassist who stole your girlfriend (I'm still bitter after thirty years !!):





Five cuts and one jumper

thank you tonmann.

Today's snippet has already been covered by culturejam and, if I remember correctly, kaycee:





Nine cuts and four jumpers.

Today's offering is the PWM:





Fourteen cuts and nine jumpers.

Please note the following:

The orientation of IC1. This keeps the board size down to something reasonable !
IC2 is a CMOS Hex Schmitt Trigger Inverter chip. That's six (the Hex part) circuits, each with one input and one output (pins 1&2, 3&4, 5&6, 9&8, 11&10, 13&12). It doesn't matter which triggers are used, so long as the unused inputs and grounded. I've used triggers six (pins 13&12) and four (pins 9&8) to keep the board size small.

Version 2 using one of the triggers as an LFO:



Seventeen cuts and eight jumpers.

any sound clips of the pwm?

There is a recent thread on here where someone built it and shared some clips. If I recall, it said something like gameboy sound generator, or something like that. Anyone recall? It was pretty cool though.

I copied those off when they came up- like I am doing with Tonmann's layouts here- for reference in hopes I will build some and/or understand something I don't yet even know I don't understand.

These were posted with a clip that did sound 8-bit game-y.

any vero layout for this?

If I'm not mistaken, this is:

because of the simplicity of the Rambler, I'll do both today:





five cuts and one jumper.





seven cuts and two jumpers

Next up is the MS-20 low pass voltage controlled filter:





At fifteen cuts and six jumpers, here's the reverse:

Thanks Tonmann for all your vero layouts!



I know the description says this a filter, but how would this circuit be used?

Basically a low pass filter (it cuts high frequencies) that takes some of the output signal and feeds that back into the buffer of the first stage - if you feed back enough signal the circuit will oscillate. I have no idea how it would sound with a guitar, so I supose we are waiting for somebody to build one and post some clips.

Today's circuit is another low pass voltage control filter:



I took the liberty of a small mod on the above schematic.
The part of the circuit that is supplying the reference (or bias) voltage is connected through the 1MΩ resistor to the non-inverting input of the op amp; if you measure the DC voltage at the non-inverting input, it will be half the supply voltage.
If the reference voltage were use anywhere else in the circuit, I would need the capacitor and two resistors (I won't go into the techie explanation), as this is not the case I can change the circuit slightly for the same result (reference voltage at the non-inverting input) and save the cost of the capacitor and one resistor, plus a bit of board space:



I've laid the board out as per the top left diagram:



Ten cuts and three jumpers.

To change the board to the bottom right diagram:

Change R2 to 2.2MΩ
Remove C2
Change R3 to a jumper

To invert the control voltage (CV) response as suggest in the small box, connect the anode of D1 to b12 and the cathode to d12.

It's also possible to make the LED switchable at the cost of an extra LED and a DPST on/on switch:

Today's offering is the very simple Smokey Amp Clone:





Not a circuit I would recommend, but as its part of the circuit snippets file...........

Another 386 circuit:





Six cuts and three jumpers

Twelve cuts and seven jumpers, here's the reverse:

Two cuts and one jumper

Seven Cuts and two jumpers

Nice and easy one today:





No cuts and one jumper - I said it was easy

Getting close to the end:





At nineteen cuts and thirteen jumpers, here's the reverse:



I made the LED/LDR combination the same dimensions as a Vactrol. For seperate LED/LDR components, the cathode of the LED goes to j3 (or l3) and the anode to n3; the LDR leads go to j8 and n8.
