We don’t manufacture tubes and can only retest them to make sure they’re okay. My stream My TV My friends. Use only type “3AG Slow Blow” fuses. Be careful as this can add massive bottom to your sound which might overpower other frequencies and cover up an overall balanced sound.
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. Let’s begin by hooking up a speaker to the new Speaker 1 “Use First” jack on the back panel of the Shiva. Click here to check if anything new just came in.

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. If you hook up only one cabinet, the impedance ohm value of amp and cabinet should match: One of the numbers in each oval is marked out with a black marker, so only the other number is important to you! Next, flick the power switch front panel, right side to the center “standby” position and let the amp warm up for several minutes.
Please read safety instructions before you use this amplifier!!! The 1×12″ combos made prior to Juneare loaded with a Celestion Classic 80 8 ohm speaker. Read safety instructions zhiva
We decided not to do this because we like the open sound of the amp if you don’t use the reverb. 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. The Shiva defaults to the Clean channel with the Reverb on when no footswitch is plugged in, however to activate the High gain channel without using the footswitch you have two options: On reverb models, the reverb is always on if the reverb footswitch plug isn’t connected.
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.
Read this owners manual completely before use to fully understand your Shivas functions. The Shiva is a masterful study of refined elegance, providing the synergy of one’s heart and hands.

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. For noise check the appropriate preamp tubes refer to f.
If you switch the Reverb in, you hear a slight level loss. Your amp comes with a 3 button footswitch, Note: This control labeled Excursion is great to dial in a full sound at low volumes or adjust the right balanced bass to a cabinet.
We prefer the Chinese 12AX7A’s. You are at the newest post.
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 mnual amp customized Keep that in mind because most of the 4×12″ cabinets are 16 ohms.
If you put the amp in play make sure you have a load or speaker cabinet manuak up, otherwise you could damage the output transformer and the power tubes. Set the Master Volume for overall Volume.
The footswitch jacks are located on the back panel.
Repairs should be done only by knowledgeable Technicians!! That way you make sure it is the Amp.
It kanual not be necessary to return the signal back into the amp. Unlike the tone stack bypass boost on the other Shiva model this boost has a separate gain stage which brings this channel into Plexi territory when boost is engaged. Comes with footswitch and manual. If you would like to use the Shiva sgiva 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.
