This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.
The Boosta Grande is a simple opamp-based boost that's pretty similar to the MXR Micro Amp. Only differences being where the pot is in the circuit and component value changes. Offers up to +20dB of boost. Should fit in a 1590A if you don't board mount the pot.
It works well without problems has a decent gain, but the gain of the MXR Micro Amp is at least twice as much, I think it is not this time, I replace my clone of Micro Amp. Thank you! By the excellent circuits, I hope you continue for a long time.
Its not working. On the original schematic I saw a C1=220uF after diode that could be for ripple and is missing here. Othre question is C10 appear as 1000uF and here is 100uF. Using a test probe test I can hear sound on input pin 2 on TL071, but no sound on pin 6 of TL076. On capacitor c6=5n6 and resitor r8=10K the voltage is dropping from 4 to 3 volts. I only potenciometer from C10K to B10k and others is the same.

ReplyDeleteIt's verified, my friend!

ReplyDeleteDo you have a project Sonic Stomp BBE?
this is a cool sound!!!
Guys... can I replace the C10K pot with a B10K?
ReplyDeleteNot able to find the exact component in this god forsaken place ... :S
B10k will work. The sweep of the pot might be a little off from the original, but it'll still function fine.
Deleteyou could also wire an a log A type pot backwards

DeleteIt's working, nice gain! I will try to find the C10K because the B10K seems to go from 0 to 100 in the last 5% :S
ReplyDeletecan i use a linear pot for that ??
ReplyDeleteYes, the sweep will be a little off, but it should still work.
Deletethanx

DeleteHello again, my issue was solved after change TL071 from another brand. The 3 TL071 that a tested before are fake.
