Flexi-50 Controls
Front Panel
First, let’s go through the various control options on the front panel:
1. Input: This jack fits a standard 1/4" mono instrument cable. If you use a stereo cable,
the sleeve signal will be ignored. Do not use speaker cable into this input.
2. Input Lo/Hi switch: This switch toggles the Input gain from low to high. With the
input on Lo (sometimes called "normal") the input signal is not boosted. You may prefer
this setting for higher output pickups or less high gain tones. Switching the input gain to
High raises the input gain, which boosts the volume of the pickup slightly. You may
prefer this setting for lower output pickups, or to drive the Flexi input slightly harder.
The yellow LED above the Input jack will light when High gain mode is engaged.
3. Volume: This knob controls the input volume into the preamp tubes.
4. Treble: This knob can be used to boost or cut the high frequency response of the Flexi.
5. Bright Switch: If the bright switch is on, an upper high frequency boost will be added
to the signal. This boost is independent of your Treble knob setting, so you could, for
example set the treble knob to roll of the high end for a darker overall sound, but turn on
the Bright switch to add some upper brilliance.
6. Middle: The middle control offers a very musical mid-range adjustment over a narrow
frequency range.
7. Bass: This knob can be used to boost or cut the bass frequency response of the Flexi.
You’ll find that the Flexi has bass to spare!
