Jetter Gear Gain Stage Blue Overdrive Guitar Effect Pedal Used

Used with wear associated with use. Minor cosmetic scratches/scuffs from handling and play. Noteworthy blemishes or issues will be described and pictured. Works as it should.

We strongly recommend using the proper power supply for any pedal. Daisy chain power supplies may not supply enough power when using multiple pedals or introduce noise into the chain. Consult the pedal manual when available for manufacturer recommended power specifications.

There is some paint finish chipping on the front. There are two missing screws on the bottom, and some light scratches. Please see pictures for details.


The GS Blue has the expected gain, volume and tone controls, but these do not yield the expected results. The pedal also has 2 switches that add to the tone shaping possibilities.

Gain: Sets the overall amount of overdrive. A lot of time was spent on designing the gain structure and the amount of available gain. It's easy to create a high gain pedal; it's another thing to make a balanced gain structure that delivers articulate and musical results. We wanted there to be enough gain on tap to drive a very clean amp into a singing violin tone, but not mush out. Settings at 2 o'clock and above will get you into the singing lead territory. At gain knob settings of 2 o'clock and above, the bias point of the circuit changes and more saturation is available. This is where the liquid-y drive tones will be found. Gain settings below 2 o'clock will provide a world of subtle to mid-level overdrive tones that sound great for many types of rhythm and lead applications. The character and flavor of the gain, as well as the harmonics and response will be affected by the interactions of the tone knob and the Hard/Soft and I/II switch settings (see below).

Tone: Passive tone control - we carefully selected components to provide a useful response throughout the entire tone sweep. The sweet spot of the tone knob is from 9 o'clock to about 1 o'clock. More extreme settings exist outside this range, but they are still musical and workable. Again, the tone will interact with different gain and switch settings. This tone control is best used as a final balancing adjustment after the other settings are determined. Many OD pedals today have tone controls that offer a very limited range and quickly become too harsh in the upper frequencies; this pedal is different.

Hard/Soft Switches: This switch selects the type of clipping used with the gain in the circuit. This is where the overall character of the overdrive is shaped and the differences between Hard/Soft become very noticeable at higher gain settings. A lot of development time went into the selection of the clipping circuits for each position so that flexibility and musicality was maximized.

Hard - More dynamic and in your face with a very distinct touch-sensitivity at lower gain settings. Hard provides a more transiently dynamic and pronounced response and feel. You will notice an apparent increase in volume, however it's actually the wider dynamic response that is creating this effect.

Soft - Is a more compressed and gain-ier tone. Use this setting for more of a liquid-y drive. This setting works great with single coil pickups. I- II Switch: This switch offers two different levels of gain, each with its own voicing. These switches have a great interactive effect on the gain setting. Not only do they offer varying degrees of gain, but the different voicings will complement a wider range of amps and guitar combinations.

I - Less overall gain and softer top end. This setting works great with brighter amps and still offers enough gain to achieve a saturated singing lead tone. This setting is more articulate and provides wonderful dirty rhythm and blues style lead tones.

II - More overall gain with stronger upper mids. This setting works great with darker british-style amps. This setting will offer the most gain and the smoothest lead settings. The higher gain will give single coils an extra push into the amp.
