The SV-Boost is the gain section of the SV-Pre. The cascading JFETs give a touch sensitive response similar to the harmonically rich 70s SVT tube gain section. Without the EQ section to drop down the signal, the SV-Boost gives a substantial amount of gain. The taper of the boost has been reconfigured so that the minimum setting is approximately unity gain. The maximum amount of gain is between 30-40 dB, depending on the supply voltage, and how strong your input signal is. Higher input signals will cause compression at very high levels of boost.
The SV-Boost works great as a first in line buffer/booster. It works equally as well as a final stage boost, pushing your amplifier for more volume and sparkle. The low output impedance will allow it to drive other pedals, preamps, instrument amplifiers, and even power amplifiers.
The SV-Boost does not use an internal charge pump like the SV-Pre. This allows the user to choose the amount of headroom, and thus the breakup character of the boost. Even at 9V, there is plenty of headroom and boost, with some breakup at higher boost settings. Higher supply voltages will provide more headroom, but the harmonics and light compression inherent to the topology will still come through well.
The DC supply should be a standard Boss style connector, center negative polarity. It can accept 9 to 24 volts. The current draw is approximately 10 mA.
The SV-Boost has a true bypass switch.
