WGS 12L 12" / 200 W / 8 Ohm

Headroom, clarity, balanced response, power...
These terms have become synonymous with a vintage American design that is known and sought the world over. WGS now pays tribute to this classic with our WGS12L. However like all of our designs, we didn't set out to make a clone. With this model we paid extra special attention to the details, producing a speaker that delivers that same even response without sounding sterile and lifeless. Boasting a cast frame, 2.5" voice coil and a 200 watt rating, and clocking in at 18 pounds, this beast is loaded for bear. As a welcome addition to the WGS fleet, this speaker is definitely our battleship.

Note from the boss: "We compared both the EVM 12L and the WGS 12L in an 806 cabinet and it was almost impossible to tell them apart. The WGS 12L is a great alternative to the original and we recommend it without reservation as a perfect replacement for the EVM 12L."

EH 7025 (12AX7 / ECC83 HQ)

Electro-Harmonix has released a low noise, low microphonic version of the 12AX7 that meets all specifications required for the tube to be designated 7025. The original 7025 tube was a 12AX7 that was tested and selected for the lowest noise and microphonics for use in the critical first preamp stages of amplifiers where noise and microphonics could be an issue. In order to ensure that the 7025 specification is consistently met, Electro-Harmonix has redesigned the structure of the 12AX7 and has implemented construction techniques to ensure the absolute lowest noise and microphonics possible. In all samples tested, noise and microphonics could not be detected.

The Electro-Harmonix 7025EH has a mid-range that gives clarity and definition to the sound and a smooth top end for warmth and balance. With these characteristics, along with the exceptionally low noise and low microphonics, the Electro-Harmonix 7025EH will work equally well in vintage and modern high-gain guitar amplifiers, as well as sensitive phono preamps.
