here the soldered side. Not wonderfull but not cold soldering too... I tried to clean with ACETONE.....

Maestro had 2 9volts batteries and not an externel connetion anyway.....and Mu-tron circuits were freehand drawn anyway.

I flipped the image of the unsoldered board to read it better respect the component side.

I founded the Mu-tron advertisement of 1976!! I think they said something good after all the 9volt battery Era!

Hey my solders are well done..I posted a photo of the unsoldered board. I'll post a photo of the solsered board but all the connections are good.believe me! I already built some pedals and 3 tube guitar amps in 10 years. I' m not a technichan anyway. I think the 18volt should be better because it's ...

Maybe, this project is a new project? because an year ago the project on GGG was different. It was a project exactly like the original (18volt). Maybe nobody have done this new project yet? don't know...I'll check it again but next week I'll have all the component to do the exactly clone of the Maes...

…I forgot….I found a little error in the wiring layout….
Here the correct layout. General Guitar Gadget will updates the site soon…

Ok Thanks a lot Idy! I'll check again everything and I'll post here the voltages of the ICs and Transistors. The IC 3080 I used is an CA 3080 EV is it correct? I have soldered even a micro LM741 (for computering I think) with the same bad result. Is the UA741CN correct? Could someone tell me exactly...

It should be a wrong ic or transistor i bought...I made an error with a component...I think...

Hi Guys, I'm gonna be crazy!! Please help!! I built a MAESTRO Filter Sample Hold with modern improvements like the layout of GENERAL GUITAR GADJED said. http://www.generalguitargadgets.com/pdf/ggg_fsh_lo.pdf Well I did everything like the layout and when I switch on the pedal in true bypass mode it ...
