Bill: you're right, I stand corrected.
mid and treble not working suggests a wiring error - did you make all the cuts necessary, and in the right places? Check for solder bridges?
I think the mid and treble do nothing because you put it after a bass
booster. There might not be any mids or treble left to adjust.
The name of that pedal is quite confusing. It's not necessarily a bass guitar booster but a bass frequency booster. But...it really just boosts everything and then throws everything above 400 Hz or so away. It does not retain your full signal.
I don't know what schematic you're using but there should be a 3.3-ish uf cap to ground at the input and a .1-ish uf cap to the power supply in parallel with the collector resistor. Try removing or lowering the value of either of these to get back the rest of your frequencies.
