DIY DriveMaster into Rebote 2.5, big volume increase!

[arma61]

Hi

so the problem is this, this DriverMaster is, on my pedalboard, just before the Rebote 2.5, everytime I switch it on, with the Rebote also on, I have  a big volume increase, this happens only with the DM,I don't have this problem with other distortion pedal when in the same position, Rebote is working properly since couple of years, and DM is working properly when Rebote is not on. I built the DM as per this schem :

and......


HAPPY NEW YEAR TO YOU ALL
