I don’t know why the pc board is red. I didn’t order that color but I like it.

can I use Opamp Buffer/Booster module as a boster in my guitar replacing my tone pot with it? If so how much boost can I expect?

I answered my own question. The Opamp Buffer/Booster module can be used as an onboard pickup booster for a guitar. Bought one and have it installed and working.
Also have a Mosfet Booster module installed in another guitar.
Although the Opamp works it has (WAG) about 30% less headroom than the MB. Anyone know why this is? Should I run it up to 18V instead of 9V? Will that give it more headroom?
Newbie having a blast getting Active punch with passive and not subject to EMG or Seymour Duncan dictating tone.
Many thanks to whoever is behind these powerful yet inexpensive devices.

Running the Opamp booster module at 18v will give it more headroom. Mosfet Booster can also be run at 18v.

Best regards, Jack

Thank you. I will try using the voltage doubler module and see if it takes the Opamp up.
Great stuff man, I wish I would have found this site five years ago it would have saved me a bunch of money.
Do you have any EQ stuff in the closet or WIP? Would really like an EQ with boost module.

Yes, parametric EQ project is in the works.
