The 5U4GB Electro Harmonix Rectifier appears in many famous amps from Mesa Boogie, Fender and more.

Valve rectifiers introduce a characteristic “sag” to amplifiers, which is a bit like compression. The result is a better sustaining note at the same volume as an amp with solid state rectification. The 5U4GBs give a better sound!

The  5U4GB produces 100 watts of HT voltage, so is excellent for 50-80 watt guitar amps. The original black & silver-face Fender Deluxe Reverb amps used the 5U4 rectifier.

We test every 5u4GB in-house before shipping. We include the test results on the box to assure quality.

The EH 5U4GB is a better alternative to replacing an aging 5U4 with a solid state rectifier. Over time, valve rectifiers lose emission and so their impedance increases. This leads to lower voltage, reducing clean headroom and lowering maximum volume.

We stock a whole range of rectifiers from EHX, JJ, and Sovtek for all amps, tested in-house for maximum quality.

★ Safety

Please make sure your amp's bias is set correctly. If not, you could hamper your tone and even limit the life of the output valves.
