FRONT PANEL CONTROLS Pro Tube IV INPUT socket to plug in a bass guitar. GAIN control + 3 LEDs to adjust the input level: CLIP too high, OK optimum, LOW too low. LIMITER switch + 2-colored LED to compress the signal (channel 2 only): green Limiter on, red the signal level is actually being reduced. For features of CHANNEL 1, please refer to the chapter CHANNEL 1-TUBE. For features of CHANNEL 2, please refer to the chapter CHANNEL 2-SOLID STATE.
CHANNEL 1 - TUBE As you can see, the three 3-way switches and TONE control act in a very complex way. Therefore I would like to introduce some remarks and suggestions regarding sound adjustments: 1. Simulation of different pickup characteristics: Each pickup has a peak in its resonance frequency in excess of which no treble can be transmitted. The main distinction in sound characteristics between different pickups is that this frequency is located elsewhere depending on pickup types.

CHANNEL 2 - SOLID STATE 2 LOW BOOST 2 positive area (1) the OL LED of the master section might illuminate, which means you enter the overload range before the master control. In this case reduce OUTPUT from channel 2. If the LIMITER is activated and threshold appears too high, readjust the EQ curve to lower levels (2). Reducing GAIN would result in a worse S/N ratio and can eventually not be recommended. Should you find the threshold is too low, i.e.
