Hi, everyone.
I tried to mod a MG15 clone circuit to a blues breaker to be used as the preamp. I lost a lot of the signal level. Only difference is no input resistor or capacitor jack in is tied directly to + (3) of the opamp and there's a 1M resistor tied to ground. Any input would be really appreciated. My attempt is to have clean to crunch preamp driving the power. I've kept the tonestack although I replaced marshall parts for fender ones as in Duncan's Tone Stack Calculator.
Thanks in advance

A schematic of your circuit would be helpful.
