JJ 12AX7 MG / ECC83 MG

Compared with the JJ 12AX7/ECC83, the JJ ECC83/12AX7 MG has a slightly smoother sound and appears to operate more linearly. It is ideal for low- to medium-gain amplifiers, audio applications, and for taming amplifiers with a very hot voicing. It is also a good alternative to the 5751 and 12AY7.

WGS ET10 10" / 65 W / 8 Ohm

The ET10 is the 10” version of one of our most popular speakers: the ET65. The ET10 boasts a tone reminiscent of its 12” counterpart, but with a bit more of a pronounced midrange. The low end from this 10 is surprisingly heady, but remains tight in all situations. Top it off with a smooth but articulate top end, and you have one of the most highly anticipated ten inch speakers to date.
