Build Reports / Re: Birthday Boost: Non Madbean

Looks great! Would you mind sharing which JFET boost you used for this project?

Hi,

Imagine the super hard on boost, but replace the boost pot with a resistor to permanently bias the transistor and then put the pot after the circuit as a voltage divider. Change the input resistors to 470K or so. I used an MPF102 for the transistor so the diode for static protection can also be removed.

I can draw a diagram if you'd like?

I would like to see that diagram, still trying to learn as much as possible. No rush, but if you can find the time..... Thanx in advance!

Paul

Here ya go:

What a cool birthday present! Looks very tidy, no PCB's in sight! And I love the graphics. 21 is 10 louder than 11......  ;D
I could build my brother a pedal for his birthday, but it would probably be used as a paperweight. He's not a guitar player, but a cool dude anyway (and a great father for my niece and 2 nephews, maybe one of them wants to play guitar!).

I wish all my friends and family played guitar so I could just give them all pedals...

Thats fantastic.

A really clean build; inside and out.

I'd be stoked to get that as a b'day present. I'd also be stoked to be 21 again  :'(

Thankyou! Well, I guess the older you get the higher your boost goes...

Nice! I'm sure it'll be a happy birthday.  ;D

Thanks! I hope so!

Well it's my little brothers 21st birthday next week so I built him a boost pedal. The circuit is very simple and based around a JFET transistor. Mediumish input impedance, nothing like SHO so not as much high frequency boost. Volume control is voltage divider after circuit as opposed to biasing the transistor itself. Sounds good. You'll notice it goes from 0 to 21! Wired point-to-point with a tag strip seeing as the circuit is so simple.

The whole theme really makes me laugh. I must admit its very clean with the footswitch attached like that. Great job!!

Thanks :)

Absolutely, and occasionally those 3 pole switches do die and to replace one mounted to the board you have to desolder it from the board which is a bit of a pain. I'll try my luck!

Mounting the footswitch to the PCB is good because a) it reduces a lot of the wiring involved with a true bypass switch, and b) saves you having to work out a way to seat the PCB in the case without it shorting on anything.

Thanks for the kind words guys.

You are welcome to post any DIY related builds, of course! This one looks great...that knob...mother of god!



Well... I think the knob suits the name also ;)

My apologies if it's uncool to post builds from other companies?

Anyway, I found this guy from France who's business is called 'My Audio Lab'. Ordered a couple of his guitar effects PCBs. Built this one today. It's a SHO style boost (hence the name). Sounds good!

Nick.

No problem. My background is more in building studio gear than pedals, and scales around dials is a must in that world! Seemed natural that I would move that over to pedals too!
