Hybrid Amplifier

Guide to Understanding a Hybrid Amplifier

A Hybrid amplifier solves most of the problems associated with tube amps, and still provides the punchy tone and responsive touch of classic tube amplification.

Best of Both Worlds

As the name suggests, hybrid amps combine the best of each type of amp in one box. Again, this is done to give you the best sound by reducing cost wherever possible.

These amps use an actual tube (usually in the preamp section) together with the solid state circuitry in the power section to create a tube tone without requiring the use of power tubes (thus minimizing cost as well as future maintenance and repair).


Hybrid amps use the best of both worlds – tube technology and solid-state design.

So you may have a hybrid amplifier that includes a combination where a solid-state pre-amp circuit may be feeding a tube power amp.

Alternatively, you may have an amplifier that uses a tube pre-amp that feeds a solid-state output stage.

Irrespective of that, these amps tend to be cheaper and can sound pretty good.

How to Make Your Own Hybrid Amp

Here’s how most make a new hybrid amp. you usually start with an existing amp, usually a practice one, and then tweak with its internals to get a different tone / increased power.

Case 1: An early circuit board serves as the amp’s preamp section, while the power amp section holds multiple 6L6 tubes. This combination gives a cutting tone and a natural response, with full-sounding, powerful volume. Bright highs make for great string definition and lead work. This amp is capable of producing tones that range from glassy clean to a mild overdrive. Effects pedals sound musical and rich when played through. A dark and complex Folded Line spring reverb add to this amp’s unique character.

Case 2: You start with a KR-5 Ethernet Repeater Guitar Amplifer and fit a Tube preamplifer and a Modded Baxandall Tonestack. You can change 3 Effects: Clean, Overdrive, Distortion. The amplifier Output power is 10W. The preamp is designed with ECC83 (12AX7), but i used ECC82. The Result: Less Distortion. If you want more Distortion use ECC83 (12AX7) or ECC85 (6AQ8). I like the warm sound of the tube. Checkout the video:

To Conclude

Guitarists want an amplification system that will give them the warm distortion and responsiveness that is found in the classic tube amps. But then they would also prefer something much lighter, and beginners would definitely like to see them at much affordable prices. This is where hybrid amplification systems fit the bill perfectly. Hybrid amps usually combine a preamp tube with solid-state components to provide a consistent and reliable device.
