Master Volume and Presence 

The Master Volume and Presence work on both channels. Experiment with different combinations
between Volume and Master Volume. You can set the Volume high and the Master Volume low or set the  Master high and the Volume low. One setting could be just as loud as another, but they will feel and sound different.

Boost Function and Bright Switch

On Channel 1, with the Boost engaged, the Tone Stack is bypassed. This means the Bass and Treble  controls are not in the circuit anymore and have no effect on the sound. This was the only way to have a  boost function on this channel with the original un boosted tone preserved. With the Bright switch pushed in you get a brighter more open sound; this is less to none effective the higher the Vol.1 is set. 

On Channel 2, with the Boost off use Vol.2, with the Boost engaged use B.Vol.2. This makes the boost  variable and you are able to set it quite different. With the Bright switch pushed in you get a brighter more open sound. This gets less effective the higher
the Gain is set but still noticeable if turned all the way up.

Effects Loop

Your individual channel volume levels contro l how hot the effects loop send signal is, depending on the  effect unit you may have to keep the channel volumes lower but you can then turn up the "Global Master  Volume" to control your amps overall volume. The Shiva's Loop is a series Loop between the Pre and Power Amp, if you have an older version Shiva made prior to 12/1/05 see below for special info. Current  version Shiva’s made after 12/1/05 now have two Effect loop sends and one effect loop return. One send is a low- level Pedal/Instrument level and the other send is a hotter-level Rack/Line effects level. You can  only use ONE loop send at a time.
This newer version Shiva eliminates the need for the special "Effects loop cable" that older version Shiva’s made prior to 12/1/05 sometimes needed to prevent effects from being overloaded from the hot loop send the older Shiva’s had. Current Shiva’s allow you to use the new low- level Pedal/Instrument level send for pedals and rack effects with inputs that overload easily. The new hotter-level Rack/Line level loop send is perfect for rack effects or pedal effects with a lot of  headroom on their input stage. If you notice, after plugging in an effect through the loop that your tone is distorting or too compressed, try using the low - level Pedal/Instrument level send for pedals and rack effects with inputs that overload easily. If you're still overloading the effects input, remember to lower the individual channel volume levels since they control how hot the effects loop send signal is, you can then turn up the "Global Master Volume" to control your amps overall volume. If you would like to use the
Shiva as a "Power Amp" only with other manufactures Preamps, plug your external preamps output into  the "Power Amp In" Input jack on the back panel, located near the Effects Loop section. The "Power Amp In" bypasses the Shiva's preamp, you can still use the Master volume and Presence controls since these controls are part of the power amp circuit

Reverb

If you switch the Reverb in, you hear a slight level loss. This is because the reverb circuit loads the amp down. On most amps you don't hear that because they don't have real reverb bypass and the amp is down loaded all the time. We decided not to do this because we like the open sound of the amp if you don't use the reverb. It is possible to change that with a very easy modification. Contact the factory for details. You have individual Reverb controls for each channel located on the back panel.
