TrebleDrive, Dual treble-booster

dpFX TrebleDrive, Dual treble-booster
Vintage, dual treble-booster, with Brian May and RangeMaster vibes.

This is the TrebleDrive, a vintage sounding Dual Treble-Booster that offers two discrete circuit topologies & sound 'characters' selectable through the Red toggle switch. You can select either the left (April) or the right (May) side.

Each side has a dedicated 3-position toggle switch  which give you the ability to select the input capacitor for each side. For each of those 2 toggle switches the middle position is the "normal" state meaning that it represents a typical sounding treble booster. The other two positions offer two different levels of added low end.

  •  Right side (MAY): A treble-booster circuit built around the BC237 transistor. This side offers you a classic Brian May sound.
  • Left Side (APRIL) A treble-booster circuit (with a little more gain compared to the MAY side) built around the BC108 transistor & having as starting point the classic RangeMaster
The only knob on the face of the pedal is a volume knob, common for both the left & the right side.
The TrebleDrive is very friendly to other pedals stacked before it or after it. For example you can place it after a distortion pedal and use it to emphasize the mids of your distorted signal.
