BLÜE MONSTER
Dual Band FET OD, ver 1.1

Late 2012 i designed and build the Blüe Monster highgain thing. The story, schematic, a onesided pcb-etch design, and sound clips are here: http://www.madbeanpedals.com/forum/index.php?topic=6968.0

... and evolution shrinks stuff, even here at my workbench. And as i kept developing my EAGLE skills (all thanx to this fantastic Place, that must be said again and again!) and also realized that i can order fabbed PCB-s for a ... reasonable amount of money, i decided to design a twosided PCB for the Blüe Monster myself. Definately exciting to populate and box a fabbed pcb of my own design. And scary to hit the stomp for the first Power up.

***

It is still the same Circuit as linked to above^^, but redesigned as a twosided pcb. The only main difference is the addition of a CLR and LED pad. The goal was to use boardmounted pots, make it fit in a BB enclosure, and i wanted to keep the "six pots gives a triangle"-design.

***

In short: This is a dual band highgain overdrive. It splits the signal in two fully phase-compensated frequency bands after the input buffer. Those two signals are then separately distorted/overdriven in two dirt Circuits based around a 4049UBE, before they are mixed together and run through a tunable two-pole LP filter for additional soundshaping. Finally a master volume.

It has been some interest around here to buy these fabbed PCB-s. I will come back regarding that subject, i want to try this very box a bit more before i start to spread them:)

Look! I'm shrinking! Same same but different.

looks to me like ribbon cable connecting a dual gang pot. This is really cool! All those pots in a really nice layout. Good work Bengt!

Vallhagen

Thanx gentlemen!

And yes, it is ribbon wire connecting the dual gang pot to the pcb. I decided to go with a dual pot with solder lugs, not boardmounted.

Awesome work again! Now the board is verified, does that mean some are up for grabs? If so, put me down for one!!

Love it! Basically the same look as I was going for with my build.

Excellent PCB layout, Bengt!

Thanx Jon!

Thanx Jacob! And thank you for teachin me/us so much about EAGLE. Without your videos i wouldnt have this design done!

Thanx:)

Yes, some are up for grabs... verrrrry soon. I have one more thing to do, that is to take it down to my rehearsal room and do some fullvolume A/B testing, comparing this one to the earlier version. I want to verify that i haven't added anything strange ... as increased noise level or other artefacts. I think this can be done today.

I have re-read through the project thread, taking notes about earlier interest of the PCB. And i have one pcb put aside for each of you who has raised your hand in interest. So, i have one pcb for you George, as well as one for kothuma.

I'll be back:)

Neither do I... (It's [Alt]+155 on Win and [Alt]+o on Mac.)

Hey there,

I'll take a PCB too if there are any left.

Thanks!
I build stuff for myself, sometimes I do 1 offs, I label them as HornBlende Audio.

Vallhagen

Thank you Pickdropper!

ThePastRecedes: Yes, i have one for you too:) ... But actually i think that was the last one.
