1.Passive Input jack - If your bass guitar has passive circuitry, connect it to the Model 3500 here. This standard 1/4” unbalanced jack provides a high impedance (100 k Ohms) input sensitivity of 20 millivolts.

2.Active Input jack - If your bass guitar has active circuitry,* connect it to the Model 3500 here. This standard 1/4” unbalanced jack provides a high imped- ance (100 k Ohms) input sensitivity of 60 millivolts.

3.Pre-Amp A (Tube) control - This determines the amount of preamplification being provided by special circuitry which simulates the sound of a classic tube amplifier (this circuitry actually includes a real tube!). Note that when both Pre-Amp knobs are used at equal settings, the amplifier will be twice as loud as when only one is used. Avoid setting both Pre-Amp knobs on maximum (“10”), since the result will almost always be undesirable distortion.

4.Pre-Amp B (Solid State) control - This determines the amount of pream- plification being provided by special circuitry which simulates the sound of a solid state amplifier. Note that when both Pre-Amp knobs are used at equal set- tings, the amplifier will be twice as loud as when only one is used. Avoid setting both Pre-Amp knobs on maximum (“10”), since the result will almost always be undesirable distortion.

5.Compression LED - Provides a visual indicator of the status of the compression circuitry. When lit steadily green (for example, when the Compression knob [see #6 on the next page] is set to “Off”), no compression is being applied. When unlit, compression is being applied to the incoming signal at a ratio of approximately 2:1. When flashing red, the compression ratio is approaching infinity (limiting is being applied to peak signals). When lit steadily red, the entire signal is being limited. This LED “follows” the incoming signal, changing continuously as different amounts of compression and/or limiting are being applied. For more information, see the “About Compression” section on page 15 of this manual.

*Bass guitars that have active circuitry normally require a battery for the circuitry to be functional.
