TrebleDrive, Dual treble booster (2 footswitch version)

Vintage, dual treble-booster, with Brian May and RangeMaster vibes. (check the simplest version here)
This is a variation of our classic TrebleDrive, a vintage dual treble-booster, with Brian May and RangeMaster vibes. It offers two discrete circuit topologies & sound 'characters'. The two sides can be used as two separate pedals working independently but they can also be placed in series.

Each side is equipped with:
- its own footswitch.
- a pair of separate Input/Output jacks.
- a Range and a Volume knob.

The Range knob modifies the response of a variable filter placed at each input which gives you control over the amount of low end present in the output of each circuit. Its behavior is similar with a tone knob: turning it clockwise will offer more treble/mids and turning it anti-clockwise will offer more low end.

--- Special feature:
If you want to place the two sides in series (May --> April) you don't need a patch cable. Use as input the input-jack of the May side (leave May-output unconnected) and as output the output-jack of the April side (leave April-input unconnected) and you will have the circuits placed in series when you engage both footswitches.

Note: If you need to place the two sides in series but in the reverse order (April --> May) you'll have to use a patch cable like you do with all the pedals you need to connect in series.

- 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 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.
