Known pedals with volume loss:
Boss TR-2 Tremolo
Fix: If your pedal was made before late 2006, remove the C4 capacitor and change out the R9 (10K) resistor with a 1/4 watt resistor of lower value. 6.8K should yield unity.
Values lower than 6.8K will increase the volume further. TR-2's manufactured since late 2006 already have C4 removed from their design, but the R9 change will still help with volume change.
Removing C7 will increase the treble.

Did the exact same, and yeilded great results.
Theres still a minor volume drop with R9 as 10k
Shouldn't this be called the C4/R9 mod
Tempted to do the same as Keeley and add a Volume knob,

They use a mids pot from a MT2, the 100k pot for the usual Depth, and the volume is from the 50kc reverse audio and a trim pot across it to bring it down around 20k. Guess a linear pot would work too.
I was going to cannibalize a MT2 for both stacked pots, one for the TR2, the other for the HF2 as an Effects control for the wet sound. |
