I put these in the V2 and V3 positions of a VOXAC15C1. They sound good. For the V1 use either a 'V1' rated JJECC83S or a Tung Sol Reissue. Both sound good with the Tung Sol offering a bit more clarity and gain. good with the Tung Sol offering a bit more clarity and gain.

I have put it in v2,v3,v4 position of my Peavey Ultra Plus following the suggestion of TT. I don't have a lot of experience about tubes but the clean is still sparkly and I don't notify any noise.I've replaced a Sovtek 12ax7 whit this. The crunch and ultra channel aren't noisy also. I'm satisfied and my wallet also! is still sparkly and I don't notify any noise.I've replaced a Sovtek 12ax7 whit this. The crunch and ultra channel aren't noisy also.

WGS G12Q 12" / 20 W / 8 Ohm

Building on the popularity of our G12C, we developed the G12Q for those times when you want the speaker to add some natural, vintage breakup but maintain clarity. With a 20 oz magnet and a 1" voicecoil, the G12Q definitely has a vintage American flavor. We highly recommend it with 5E3 style circuits.
