BBE Boosta Grande

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.

  1. 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.

    1. B10k will work. The sweep of the pot might be a little off from the original, but it'll still function fine.

  4. It'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
