Synergy SYN-50 valve amp head

World's most customisable valve amp

Written by

Cian Hodge

It's impossible to match that feeling of an in-the-room, air-pushing guitar amp. The 6L6 tube-equipped SYN-50 head combines traditional guitar setup with Synergy's unique preamp module technology. Effortlessly tap into your favourite amp sounds by inserting up to two preamp modules. There's an incredible selection of Friedman, Soldano, Diezel, Bogner, Plexi preamps and more to discover.

As well as the vast tonal possibilities, the SYN-30 houses a number of important features any modern day guitarist regularly relies upon. These include switchable cab impedance, MIDI footswitch capabilities, an effects loop, direct-in cab simulation, ground lift and an onboard clean amp channel.

Here's what Synergy say about the SYN-50 head:

If you want the power of the Synergy platform but prefer to stay with a straightforward, tube amp-based rig, the SYN-50 Dual Module 50W All-tube head is for you. Based around an 6L6 power section, the SYN-50 is capable of singing with the best amps out there.


With docks for two of our preamp modules, you're able to outfit this head with four channels of boutique-quality tone. And while the three 12AX7s and an 6L6-based power section push the sound of the modules through your favorite cabinet, the amp’s  global Presence, Density, and Master controls shape its overall character. The SYN-50 brings together classic tube amp performance with the modern flexibility you demand.

Try the T/DLX and Diezel VH4 modules to go from California cleans to ferocious high-gain. Or maybe you'd prefer to pair our Morgan AC and Friedman BE modules for various shades of British-style chime and crunch.

Swapping the modules couldn't be easier. Simply loosen the thumbscrews and change out the module for a different tone. With the SYN-50, you'll have the power and tones of Friedman, Morgan, Soldano, and more at your beck and call.


With so much tonal power and so many sonic options onboard the SYN-50, we made sure to offer you two flexible ways to control it. The Synergy 4F 4-button foot controller is essentially a fully programmable MIDI controller. From the factory the four buttons recall the channels on your preamp modules. But with a simple procedure, you're able to program the pedal to your needs.

If that still isn't enough, the Dual Module 50W All-tube Head is fully MIDI capable. And because it accepts both 5- and 7- pin connectors, it works with almost every MIDI controller out there.
