If you think something is wrong with your Amp, play straight into the Amp with nothing else hooked up other than a Guitar. The Loop circuit is always in the sound chain even if nothing is hooked up to it. Shiva 6L6 models made mnual June approx. Be careful as this can add massive bottom to your sound which might overpower other frequencies and cover up an overall balanced sound. Featuring two highly evolved channels, capable of clean tones that shimmer like icicles in the deep of winter moonlight and tube saturation that is so rich and powerful it should be illegal in the free world. Your amp comes with a 3 button footswitch, Note: The Shift button will as it is labeled shift the EQ.

All measurements include handle and rubber feet. How to use it: Read this owners manual completely before use to fully understand your Shivas functions. Experiment with different combinations between Volume and Master Volume. One setting could be just as loud as another,but they will feel and sound different. 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 unboosted 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. On Channel 2, with the Boost off use Vol. 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.
You can only use ONE loop send at a time. 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. If you want to use an instrument level floor Effect unit or if your line level rack Effect unit is too sensitive for the hot send signal, you can use our special built in Boost Amp. All you need is a special level ducking cable, available from us or you can make your own, see the "How To Make Effects Cable" link on Shiva portion of our website.
Plug the output of your Effects into the input of the Boost Amp located on the back and hook up the output of the Boost Amp to the return of the Fx Loop with a short jumper cable. This is necessary because of the lower output send level so it does not distort the input of your FX but we have to bring the level back up after it leaves the FX in order to keep the original tone of the amp.
Remember if you use the Loop the Channel Volume controls work like send levels, the higher you set the Volume, the more Level comes into the Effect. Set the Master Volume for overall Volume. The Loop circuit is always in the sound chain even if nothing is hooked up to it. If you want to bypass your FX, you would have to do it on the FX unit.
If you plug into the send you tap the signal of the Pre Amp and you could also send it to a recording device, mixer or another power amp etc. It would not be necessary to return the signal back into the amp. On the other hand if you plug into the return you disconnect the Pre Amp from the Power Amp. You could use your Shiva just as a Power Amp. As always, you must have the amp under load from a speaker cab or load box or damage may occur. This is because the reverb circuit loads the amp down.
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. Be sure to set the impedance switch correctly, use the 16, 8, or 4 ohm setting to match your cabinet. There are many ways to wire a speaker cabinet and you need to know what yours is rated at.
To add a second speaker cabinet, use the second speaker jack and make sure both cabinets have matching impedances, the speaker output jacks are parallel so be sure to change the impedance selector to "half" the impedance rating of one speaker cabinet. For example: using two 16 ohm cabinets switch the impedance selector to 8 ohms or to use two 8 ohm cabinets you must change the selector to 4 ohms.
Next, flick the power switch front panel, right side to the center "standby" position and let the amp warm up for several minutes. This will stabilize the circuits and prevent a painful surge from flashing through your tubes. When ready to play, flick the power switch up to the "play" position. This older Shiva does not have an ohm selector, it has 3 speaker output jacks each labeled with an oval containing 2 numbers in it. One of the numbers in each oval is marked out with a black marker, so only the other number is important to you!
If you hook up only one cabinet, the impedance ohm value of amp and cabinet should match: 4 into 4, 8 into 8 or 16 into If you hook up two cabinets they must have the same impedance, same ohm value. Shiva 6L6 models made before June approx. The older 6L6 Model have one 8 and two 4 ohm speaker outputs the transformer has an internal 2 ohm tap also, so outputs could be wired to 4 2 2 or 8 4 2 ohms if you wanted your amp customized Keep that in mind because most of the 4x12" cabinets are 16 ohms.
The footswitch jacks are located on the back panel. Current Shivas have a 4-position rotary switch on the right-side back panel. This rotary switch is only active when the footswitch is not plugged in.
NOTE using the "older version" Shiva without the footswitch connected: Some people may not need to use their footswitch because they only need one channel to play thru. The less gain the tube has and the earlier the tube is in the sound chain 1st, 2nd,.. Make sure you turn your amp off when you switch tubes and be careful the tubes might be very hot!!
Do not touch tube sockets with fingers? Even after turning your amp off and unplugging it from the power outlet there could be enough voltage stored in the capacitors to give you a lethal electrical shock. Read safety instructions again!! Speakers The 1x12" combos made prior to June , are loaded with a Celestion Classic 80 8 ohm speaker. If you want a more open vintage sound try a Celestion Vintage 30 NOTE: be carefull how loud you play because the Vintage 30 speaker can handle only 60 watts.
Subject to change, depending on availability on Speakers. Troubleshooting Make sure your read and understand the safety instructions!!
Repairs should be done only by knowledgeable Technicians!! Always make sure your Cables, Guitars, Effects and Extension Cabinets are working and hooked up correctly.
If you think something is wrong with your Amp, play straight into the Amp with nothing else hooked up other than a Guitar. That way you make sure it is the Amp. For noise check the appropriate preamp tubes refer to f. Tubes are delicate and have a limited live span depending on operating time, temperature and mechanical influences. We let our amps run for at least two days before we ship them to make sure that the tubes work properly but since they have a glass housing and delicate little plates inside them it happened that they got damaged during shipping.
The Main fuse for and volt models should be 3A 2A for volt. Use only type "3AG Slow Blow" fuses. You can get those from Radio Shack. The HT fuse blows usually if your power tubes are bad to protect the poweramp circuit from getting damaged.
If the Main fuse blows it could be just a voltage peak from your power outlet. Put a new one in and see what happens. If it blows again give us a call. In most cases it is just a 20 cent rectifier diode for the plate voltage which went bad.

Vugal The Shift button will as it is labeled shift the EQ. The Main fuse for and volt models should be 3A 2A for volt. This gets less effective the higher the Gain is set but still noticeable if turned all the way up. Always make sure your Cables, Guitars, Effects and Extension Cabinets are working and hooked up correctly. Best to keep low at higher volumes. The EL 34 Model has one 16 and two 8 ohm speaker outputs the transformer has an internal 4 ohm tap also, so the outputs could be wired to 8 4 4 or 16 8 4 ohms if you wanted your amp customized.
Bogner 20th Anniversary Shiva and Ecstasy Amp Reviews
Featuring two highly evolved channels, capable of clean tones that shimmer like icicles in the deep of winter moonlight and tube saturation that is so rich and powerful it should be illegal in the free world. Foot-switchable boost function for both channels, variable for channel 2. Standard Shiva - EL34 models are 80 watts and have a nice throaty growl with aggressive English-style midrange to punch thru the mix. There is more than enough bass response to rearrange your living room furniture, if needed.
Channel 2 Shiva The 20th Anniversary Shiva is a similar beast to its standard brethren, but has some extra trimmings that help differentiate it from the rest. The KT88 also exhibits more of a hi-fi effect compared to a more run-of-the-mill set of 6L6s or EL34s. The head utilizes a simple two-band EQ section with bright switch and a preamp Gain control for its clean tones, and a more familiar three-band EQ to alter and shape its gain tones. Working in tandem with those controls are two buttons labeled Shift and Mode, with the former shifting the EQ spectrum to have less mids, and the latter to add more aggression to the sound. Using a Fender American Stratocaster, I was able to get the classic Shiva clean tone with much more heft and definition. Using the reverb control on the back helped deepen the sound.
